HAP AC

You can't increase it, you can lower it.

Thu Feb 25, 2016 7:58 am

Maybe i am too dumb or too blind or i just dont get it, but how do i increase the tx power on the hAP AC to increase range?

Default value is Maximum. It already transmits at 1W. Range should be more than your phone can handle. Only lowering is possible.

Have someone make a test about 5Ghz signal strength ? Some tests to File Transfer via 5Ghz if possible.

byry · Thu Feb 25, 2016 4:00 pm

Hello.

Network name for 5ghz and 2.4ghz can have the same name ?

Thu Feb 25, 2016 4:05 pm

Why not ? They do not "see" each other. Client @ 5GHz will see one and these @ 2.4 GHz will see the second interface.
You can have same name on any interface to use "roaming" function .. when the client losts access to one AP then the device looks for other AP with same name.

littlebill · Thu Feb 25, 2016 4:18 pm

can anyone else confirm the same distance limitation the other user posted compared to the 951?

Of course you can use the same SSID. There a feature named "band steering" would be helpful. It make sense to move Wireless clients to the 5GHz band as long as the signal is strong enough.

I received my hAP AC's today and am currently running them through several tests.

For now I've been doing access-point tests on it without CAPsMAN or anything like that. Just setting one to "station pseudobridge" and the other to "ap-bridge" like I had previously for bridging my main PC to my network.

Quick results (more detailed will follow later) is that I'm hitting 500Mbits without too much issue but that at that point the CPU is at 99% or around there and that does seem to be the current bottleneck. I tested it using 6.33.5 with wireless-cm2 and with 6.35rc12 using wireless-rep on both ends, that doesn't seem to make much of a difference.

All tests done using iperf2 on 1Gbit interfaces and beefy Quad-Core machines on both sides.

I have more detailed results which I will publish later on. I will also do some simple NAT tests for those interested.

I got my hAP AC.

The results are not that great. I get around 450Mbps on AC (with MacBook Pro 2015) to LAN. I get around 300-350Mbps with NAT (85% of CPU).

What is interesting is the CPU usage when the hAP AC is sending: it's then around 20-30% (50% when doing AC+NAT with 300Mbps TCP), on the other hand when receiving at full speed it is 95-100%.

MetaRouter is not working for RouterOS. It's is constantly in booting state. When I put the OpenWrt image, it did boot, but the AC performance is cut to around 200Mbps with NAT. The CPU is constantly at 100%.

So in the end, as I assumed: this is unpowered device with unpowered CPU with a unreasonably small amount flash (16MB) for that class of the device and for this price.

And as with my previous tests, the MetaRouter performance s.cks (even when doing nothing). It basically kills the performance of RB :(

One funny note and disappointing. I have Archer C7 v2 (the Archer C7 v2 has the same CPU, same AC chipset and same amount of SPI storage [16MB]). To Archer C7 with OpenWrt on board my MacBook Pro connects with 1300Mbps (as you would expect when the distance between router and Mac is 80cm and there's no other networks around), but the hAP AC fails to get more than ~850Mbps.

Final word, with recent improvements in RouterOS (fast path and fast track) this gives a big boost to the performance, but as for Wireless I'm a disappointed. It's significantly faster compared to OpenWrt with the same specs. However, if you add to that picture broken OpenVPN in RouterOS I would discourage to use that device for home if you have less than 200Mbps Internet connection. It may be quite reasonable choice if you have at least 250Mbps Internet, but then I would invest a little more bucks to get more powerful one where you can also connect printer, and setup some DLNA server.

Let's hope that v7 gets the improved OpenVPN.

Interesting. What actual transfer rates do you see with the Archer C7 when doing a transfer over AC?

I've been testing some more and also with different clients (an AC phone and N laptops) and for me range and throughput seems to be good. I guess it's not great/excellent as some others, but I believe it's well within line as to what is to be expected for what the device is. If you need that, buy a ~500$ consumer router I guess, the hAP AC is more suitable when using multiple access-points. It's giving me more throughput then I had on my N devices before and it's consistent. I tested several spots in the house and it seems to be doing just fine.

Also, pings over my bridge are rock solid and the pair never drops a ping.

Realistic AC throughput is more around 400Mbit (~50MB/sec) in a good situation. At that point it's not yet CPU limited but rather radio connection limited. That also brings me to an interesting point. Getting more then 400Mbit would be a real-world challenge on the radio and reception strength part. So having the CPU limit at 500Mbit (60MB/sec) might not be such a horrible issue when using it as a dedicated access-point. Since you won't reach that high in a normal situation anyway.

On Archer C7: 1053-1170Mbps 3 streams. On MikroTik it has problem to use 3 streams, usually it uses 2.

500$? not really I would say around 200-250$.

One more note for all concerned that switch chip has only 1Gbit CPU link. You should not be if you have asymmetric internet connection. It easily achieves over 800Mbps throughput when routing between two ethernet ports. I did test that.

I wonder if this is due to internal vs external antennas. Internal does look prettier, but I'm sure most of us are power users who want the best performance.

Does anyone know if the replaceable antenna is ufl or mmcx? It's hard to see from the photos.

keisim · Fri Feb 26, 2016 1:21 pm

Normis,

Pictures shared by G2Dolphin show antenna connectors for each of 6 streams. 4 connectors look like switchable ones (internal antenna is disconneted when plug is inserted).

Could you please let us know the type of these 6 connectors?

I planned to buy 2 hAP acs for home (1 for each floor) but I'm afraid of range. I would like to have a posiibility to attach 6 external antennas in a custom box to increase RX range (TX should not be a problem beacuse of high RF output power).

Fri Feb 26, 2016 1:34 pm

Those are uFL connectors, but they have epoxy on them. They can't be easily taken off.
The others are test points, not connectors.

Quindor · Fri Feb 26, 2016 6:04 pm

@ayufan So you are seeing a higher connection rate. I would imagine so with external antenna's, but what actual transfer rates are you seeing when doing a comparative test?

I've been doing some more tests, this time with the hAP AC configured as my "production" access-point using a CAPsMAN setup.

Piping all the traffic through CAPsMAN (No local breakout) seems to lower the max throughput to around ~280Mbit (35MB/sec). At that time the hAP AC is again hitting CPU limits. So running without local breakout seems to halve the maximum throughput that can be achieved. My CAPsMAN controller is a CCR1009 which doesn't even see much of a raise in CPU usage for that amount of traffic, so it's not the bottleneck.

All in all the device has been performing fair I would say. The range seems decent, but trying to get the best transfers rates needs me moving everything around to find the most optimal signal strength, nice in a test setup, but that won't fly during normal usage. It's also always faster then my N setup was before this and the radio's seem very good at handling multiple clients and consistent ping times/latency. In that regard I like the hAP AC very much.

(I can't compare it with a RB951G-2HnD because I don't own one, the range does seem to be about the same as the RB2011 which I've used a lot).

I do also notice the difference in CPU usage when sending or receiving, it's odd to see. In CAPsMAN mode this also seems to have a direct influence on transfer speeds (when the radio link is very strong). I can do 35MB/sec with max CPU one way and 45MB/sec the other way without hitting a max CPU. Both hAP AC connecting to each other in this setup.

All-in-all I like the hAP AC as an access-point. Yes it has it's shortcomings, but I feel that the combination of the antenna sensitivity and CPU power kind of matches each other for the price. Yes I can get it to CPU limit with 2 hAP AC's connected together and having them positioned in the most ideal way possible, but that's not a real life scenario. In most real worlds scenario's, with the antenna's that it has, the CPU will be enough (only barely in CAPsMAN mode though). So is it the greatest AC access-point out there? No, certainly not. But I think it does well for the price that it costs, both in sensitivity/radio's and CPU power.

As a router/firewall/access-point you will have to manage your expectations. If you want AC and a decent router/firewall for up to a 100 or maybe 200Mbit link. Get it, it's an awesome little device! You will be able to use the your full Internet speed over wireless and all will be great!

Anything more then that and you will need to start splitting tasks up. Get a HEX as gateway for instance and the hAP AC as your access-point. Need more power, get a RB3011 or a CCR1009 like I have and get several hAP AC for your home or office situation and you will again have a great setup.

Do you want bleeding edge speeds combined with maximum coverage and Gigabit routing speeds all combined in one device? The hAP AC isn't going to do that. A consumer router of around 300$ or more will. That doesn't give you the power of RouterOS though, but that's a choice.

p.s. I will try to write a blog post soon with more detailed findings and test results and will post the link here when it's done.

Awesome write-up. Did you happen to try it using CAPSMan, but with local forwarding? That's a scenario I've considered, and think this would give you the most speed through the AP because it removes the encapsulation/decapsulation burden from the hAP's CPU.

aleh · Sat Feb 27, 2016 12:36 pm

Anybody had time to check the idle power consumption? E.g. one eth connected.
Thx!

Quindor · Sat Feb 27, 2016 9:46 pm

@aleh Doing some tests I judge idle wattage to be around 3 to 4 watt. The max power usage I don't know yet, but the data given is confusing. Routerboard.com states max 17 watt, the little paper included with the hAP AC in the box says 5 watt. I'm inclined to believe the max 17 watt because the adapter that comes with it is a 24v 1.2A one, that equates to 28.8 watt. Mikrotik also uses 24v 0.8A (19.2 watt) and 24v 0.38A (9.12 watt) adapters. If the stated 5 watt would be correct, they would have included a lower amperage adapter so I'm thinking 17 watt is the correct max value.

Interesting results!

It seems loading the hAP AC with firewall (connection tracking on) and NAT, it doesn't slow it down? I just setup a situation where I have a hAP AC connected using a cable to my network, setup NAT and FastTrack, DHCP, DNS, etc. I turned on wireless and bridged it to the LAN ports on the hAP AC and tested with a 1Gbit cable.

Then I got a second hAP AC and pseudobridged it to the first hAP AC. It got a LAN IP as expected and I continued doing the same tests. To my surprise I'm still hitting the maximum of ~500Mbit! Even slightly above it because they are situated closer together. That would mean, performing the NAT for those 500Mbits of traffic doesn't cost any performance? Reversing the traffic flow did load it higher (100%) but still produced up to 480Mbit! All going through wireless and going through NAT.

I will have more detailed statistics on my blog but the hAP AC seems suited to route/firewall a Gigabit connection (when using fasttrack) and even over wireless it seems to be able to serve the full 500Mbit to clients without slowing down!

Remember though, this is without any other rules. Just NAT and Fasttrack.

It's very great review !!!

the hAP AC will never be able to achieve it's 3x3 AC radio maximum a 1300Mbit link would allow for. Realistically and the highest I've ever seen in a review that would result in a transfer of about ~700Mbit / 87,50MB/sec. So the hAP AC is not that far off but still, strictly speaking it is CPU limited.

@normis for next generation version, can use dual core CPU ?

RouterboardMan · Mon Feb 29, 2016 6:38 am

Does anyone know how the antenna's work in this router?
I can see from the picture and from opening one up there is only 1 antenna on the 3rd chain.

How do the first and second chains get signal with no antenna?

I have 2 of these and one I have really poor range and the second works well.
Literally I go 6 metres away and nothing, compared to the other I can go more like 20m. This is on the 5Ghz.

I thought that maybe the antenna was loose but I opened it and it was fine.

I also have issues where the radio doesn't accept new connections/get DHCP and I can see that the radio is on but I can't connect to it and in Winbox interfaces I see 0/0/0 packets rx/tx etc.

It seems to randomly start working again without me needing to do anything.
I did notice that the wireless light goes between sometimes solid green, green/red flashing, solid red. I don't know what they mean.

I'm pretty familiar with RouterOS as this is not the first RouterBoard that I have had.

Performance wise WAN/NAT I have a 100Mb connection and it shows no slowdowns and uses about 12% CPU so I'm pretty happy. Coming from a RB2011 which could get 100Mb but at 50% utilisation with basic rules or 100% with VPN/QoS rules on it.

RouterboardMan · Mon Feb 29, 2016 7:02 am

Also does anyone know/think it would be worth replacing the antenna's with these?

kiler129 · Mon Feb 29, 2016 7:10 am

Not a chance - proper beamforming in 802.11ac require specific antennas & it's placement.

I can see that there are 3 cutouts in the case where the antenna's could mount to, but they have placed the sticker over it to cover the holes.

They have universal form for plastic molding. They are pretty expensive so it's smart to use one for multiple models - most of companies are doing that.

Are you suggesting that the 3rd chain antennas are not meant to be user replaceable?

Mon Feb 29, 2016 1:42 pm

Yes, we never mentioned that antennas can be replaced. You could technicaly remove the glue and replace two antennas from six, but I don't recommend doing that. If you like to build, I can recommend our PCB products where you can make dual-band devices (RB922 and similar)

brwainer · Tue Mar 01, 2016 7:00 am

How do the first and second chains get signal with no antenna?

See the weird shaped bent metal bits in the corners of the PCB? Those are the antennas for the first and second chain. That is very common for devices that have no external antennas, almost all manufacturers are doing that now. I wouldn't expect them all to be doing that if there aren't good reasons for it.

i think power supply sizing takes in count the USB port connected device power consumption that's 7 watt and POE output feature which is 0.5amp capable that takes 12 watt in theory leaving 10 watt for AP that's 17 watt for AP with USB device connected

I've been searching these question in Google, in these and in Lattelecom forum but didn't found a reply... maybe local guys from these forum know reply?

Quindor · Tue Mar 01, 2016 5:22 pm

Yeah, those UAP-AC's where running very warm!

The hAP AC seems to run luke warm to the touch. Internal heatlh mostly hovers around 46C. Using a laser thermal meter the outside of the case is around 32C to 34C on the top and the vents (the chassis is well vented) are a bit hotter. The most heat comes from the bottom side where I can measure up to 40C with the laser thermal meter. It's just luke warm to the touch though. So I don't see any issues there.

It's certainly not as scorchingly hot as the UAP-AC would get. That design also had the issue that the only vents the chassis had was screwed against the ceiling thus couldn't vent any hot air anymore anyway. The hAP AC has rubber feet lifting it off the table or wall you put it and all in all has a better vent design all around.

Unfortunately I cannot perform reliable measurements because my server currently has a 10/100 card, so it's useless to do a test with the BTest only.

QCA9558 articles that talk about performance improvements:

Well, it´s FreeBSD:
10/2015:http://adrianchadd.blogspot.de/2015/10/ ... ce-on.html

The bug is fixed and things perform now at a much faster rate - 720mbit. Yup, it bridges at 720mbit and it routes at around 320mbit

But this one is Linux:
2/2016: http://people.netfilter.org/hawk/presen ... ce_BoF.pdf

Example: Routing/NAT speed, base: 268 Mbit/s
● After insmod nf_conntrack_rtcache: 360 Mbit/s
● After rmmod iptable_mangle: 390 Mbit/s
● After rmmod iptable_raw: 400 Mbit/s

There might be improvements for the RouterOS, aswell?

i meen how MB/s you see when transfer files via Samba for ex. between two laptops via 5Ghz.

michaelahess · Wed Mar 16, 2016 6:55 pm

I'm considering this device but wanted input from those of you more knowledgeable than me!

I currently have a 60x4 cable connection with a Netgear R6200 being used as just a router with DD-WRT. I then have a Netgear R6300 being used as an AP. Around 30 wireless devices, 1/4th are AC, the rest a split between G and N.

The Netgear's go into my CRS125-24G-1S-2HnD-IN that's only used as a switch. That switch's router function and my old RB750G couldn't handle my wan connection, speedtests would regularly show 30-38 at the most, with no rules even. So the R6200 was used to replace that.

Will this new device be able to outperform the R6200 and have comparable wireless range/speeds to the R6300? I believe the R6300 is a bit slower than the Archer C7 someone mentioned here, so I'm hoping it would be indistinguishable from those routers wireless wise?

I currently do get the full 60x4, usually a bit more, around 64-68 at times, with wireless over the R6300/R6200 combo. Internal file transfers are not really an issue but I can push a few hundred Mb usually to my NAS. The switch will easily do 800+Mb between wired clients so I'm pretty sure it's not bottlenecking me any.

Any thoughts or suggestions would be greatly appreciated, thank you!

Quindor · Wed Mar 16, 2016 9:52 pm

@michaelahess

Depending on desired rules and such, it should easily suffice.

If you read back a bit, or look at my review here, you can see it should be able to handle up to 500Mbit downloads, from internet using NAT over wireless when you have a good AC wireless connection with it.

Realistically with some more rules in the firewall, a bit of VPN and on the wireless side some other signals in the house, walls and distance you should still see around 200 - 300Mbit AC connections (effective TCP throughput, much higher connection speeds) and a bit more over LAN I suspect.. It can easily handle all the routing and stuff like that at the same time.

So yes, I think it could be a good fit and you could consolidate your equipment a bit too!

p.s. With some setting changes I believe your CRS125 should be able to handle it easily too.

michaelahess · Wed Mar 16, 2016 10:45 pm

Thanks for that Quindor! I am aiming to consolidate. I tried all sorts of things with the CRS but just couldn't get it, even with a very basic NAT config, to hit over 30ish. I don't mind leaving it as a switch, it replaced my excessive cisco 2960s.

I'll order one of these and see what I can get out of it. Thanks again for the quick response!

Happy to help

It's a common problem, have you tried the following?
http://forum.mikrotik.com/viewtopic.php?t=92711#p463429

The CRS125 should easily be able to handle 60Mbit. Up to 150Mbit or 200Mbit. With fastport/fastpath much more!

michaelahess · Thu Mar 17, 2016 4:40 pm

I stopped fiddling with the CRS about a year ago. Haven't tried the queue or fastpath stuff I don't think. I bought it as a switch anyway, just figured I'd try the router function when I got it. Used the wireless for a bit, but it's even disabled now. When I get the HAP I might start playing a bit more, thanks for the link and suggestions!

I would like to give you guys a heads up and ask for advice, because it seems there is a faulty series of HAP AC with somehow corrupted switch causing terrible performance on ethernet ports - I still hope its some kind of software issue (or maybe wrong config) but support is not responding to our emails, so we are kept in the dark here...

My suspects were PPPoE or configuration issues, but it's quite possible it's something with the switch. Unfortunately I didn't have the time to investigate further and issue a formal support request. But your experience makes me think it's time for that

Thanks.

based on my experience

i think no matter the brand and no matter what marketing says:

maximum devices associated recommended are 50 per radio

of that 50 associated devices maximum 25-30 devices with concurrent traffic per radio

that's for maintain an acceptable to just good performance and stability, keep in mind a wireless radio is a shared half duplex medium that is the available bandwidth is shared between devices

another important thing is: the radio will work at the speed of connected device using it at that specific instant, for example when you have a 802.11n 2x2:2 2.4ghz radio on 20mhz channel you have a theoretical 144mbps maximum data-rate, that's equal to a maximum real traffic throughput of around 80-120mbps using a client supporting 2x2:2 with a perfect signal quality and very close to the access-point, but most clients are 1x1:1 that leaves a maximum data-rate of 72mbps that's equal to a maximum real traffic throughput of around 40-60mbps with a perfect signal quality and very close to the access-point, but most devices in a good scenario get data-rates between 24mbps-65mbps that's equal to a maximum real traffic throughput of around 12mbps-35mbps.

That 12mbps-35mbps is the real capacity shared between the connected devices if you divide the best case 35mbps between 30 concurrent devices you have 1.1mbps per device.

If we move to 5ghz 802.11ac 3x3:3 radio on 40mhz (in most scenarios 80mz will be not viable without co-channel interference) in the best case you increase to a 70mbps-100mbps of total real capacity, that increase to 3.3mbps per device using 30 concurrent devices.

Of course i have seen radios with 100 devices associated but only the management traffic needed generated degrade the performance and saturate the spectrum.

is not the same testing with 1-5 devices than testing with 40 or 50 devices, things change a lot

QoS have an influence on this check this image taken from another vendor public presentation they even not test beyond 32 concurrent devices

we can see:
for voip the max recommended concurrent device count is around 14 devices beyond that performance degrades
for video the max recommended concurrent device count is around 25 devices beyond that performance degrades
for another kind of traffic the max recommended concurrent device count is still around 25 devices beyond that performance degraded but at a rate less pronounced than voice of video traffic

I follow the logic - however I recently asked my distributor about about doing an outdoor event and they recommended Ruckus saying:

Ruckus would be a better option as each AP can cover up to 500 users and is designed for Density amongst users in these types of environments

I know they have BeamFlex+, but the detail says it's about synthetic polarisation and I find it hard to believe that offers the claimed

8X expanded coverage

, but perhaps it really is worth paying top dollar for tog dog equipment.

Duplicate post about a hAP AC related problem that I encountered two days ago:

I noticed that when all three chains were enabled on the 2.4GHz interface of the hAP AC, not all devices could associate. For example two phones, one with Android and the other with Windows Phone could not connect, even at 2m away. When I turned off chain 2 (the third chain) the devices which were not associating before, could connect successfully. Same with chain 1, although speeds seemed to be lower in this case.

The 5GHz interface does not seem to have such a problem. I think (I am not sure though) that this is something that occured lately. Unfortuantely, it was not reported earlier so I cannot give any further info. But my observation above was made two days ago, with RC45. It existed for at least two weeks back though.

Yes, you can order the international model and use it, however it's your responsibility to set proper country in settings. I believe the US-one is the same as the international one except the country setting is enforced by the wireless chip firmware rather than by ROS.

So I have a RB951G and fairly happy with the coverage however the wifi is dropping out until a reboot of the device brings it back. It's up to date at 6.34.4. I know that it shows a 1000mW power output for the wifi where the HAP AC doesn't mention the power. Can anyone offer any info on this? How do they compare?

kiler129 · Fri Apr 08, 2016 3:48 am

US company cannot legally sell you product not complaining with FCC rules. However if you buy from company aboard (e.g. EuroDK via Amazon or via their website: http://www.eurodk.com/en/products/wifi- ... ard-hap-ac) they will send you the router, but you're the importer and you're responsible for everything.
Basically it's not a problem if you mount this AP in home and use whatever frequency you like unless you're not leaking it outside your walls. The problem in USA are the walls itself - they are mostly... well, made of paper. In my home I can see (using just my builtin laptop wireless) dozen of 2.4 networks from apartments located easily 60m from me. FCC is just protecting the space in 5Ghz to prevent the same situation. Also some frequencies are colliding with weather radars.

From the hAP AC brochure, it shows as 29dBM for 2.4Ghz and 28dBM for 5Ghz. That's 794mW and 631mW respectively. Hope that helps.

Yes, it has the same dimensions as the RB951G, even down to the spacing of the plastic feet. To be honest this is probably the best way of doing things, I didn't get as large of an improvement as I'd hoped from using custom omni antennas.

We have made some tests already with multiple Android phones and didn't notice any issues with third chain however we do understand that there are various ways to configure AP and maybe some configuration you made cause this.

Please make sure :

1. You are using latest RouterOS version (current or release-candidate);
2. You are using latest Firmware version;
3. You have enabled wireless-cm2/wireless-rep package;
4. Antennas in case is properly attached to connectors and does not touch the board;
5. You have added wireless logging topic

/system logging add topics=wireless

After previous steps please repeat test with multiple devices and share following information with us :

1. Log output;
2. Wireless export output;
3. Wireless registration table output (right after test);

Atlantis · Sat Apr 16, 2016 2:12 pm

I had the same behaviour and it was wireless interference from other devices. But you wouldn't guess which - wireless mouse RECIEVER. Yes, reciever. I have PC near my hAP ac and when the PC is running and reciever is plugged in, the wifi stops working. Like 95%times it won't even connect, the other 5% it works 10seconds and then dies. IT shows high frewuency usage like yours do. I did another measurement with my mAP and it shows zero wireless usage.
Maybe the wireless in hAP ac is more sensitive. But is is strange..
I currently don't have time to do some real side by side comparison with identical AP config but you are not alone

mrz · Mon Apr 18, 2016 3:18 pm

It is possible that you are holding router too close to receiver. They can interfere with each other. Typically wireless mouses stops working, but it can be also other way around.

Just put router further away from your PC.

Turning off CapsMan and just setting the unit up as an AP.... numbers get much better.

Mine are measuring just fine too. I believe you have a faulty voltage measurement chip. Shouldn't effect the performance of the device but if you require it for remote readout, you should get the hAP AC exchanged.

Also, this kind of potential hardware issues is best sent to mikrotik support. Also asking on the forum is just fine of course.

p.s. Just to be sure, if you are injecting your hAP AC with passive POE, how long and what type of cable is connected? Using a very long cable could also cause this drop in voltage. If this might be the case, also test with the adapter directly connected to the unit.

Hi guys,

Just got a hAP AC and connected it out of the box. It sits just behind me for try-out.

I connected to it and set a wifi password, nothing else is changed for starters.

I fired up Xirrus WiFi Analyzer an ViStumbler and see a difference in 2.4 and 5 GHz signal strength: -25 dbm on 2.4 and -50 dbm on 5 GHz. Is this normal? I would expect them to be close together, because it is only 1 meter distance?

Or is some additional changes in settings required?

It is just my first steps in the Mikrotik world so I might be wrong off course.

I fired up Xirrus WiFi Analyzer an ViStumbler and see a difference in 2.4 and 5 GHz signal strength: -25 dbm on 2.4 and -50 dbm on 5 GHz. Is this normal? I would expect them to be close together, because it is only 1 meter distance?

Or is some additional changes in settings required?

It is just my first steps in the Mikrotik world so I might be wrong off course.

You should configure wireless. At least country is needed to make TX-Power accurate. Then you might have different 5GHz Bands with different TX-Power.

kiler129 · Sat Apr 30, 2016 8:27 am

Little differences between 2.4 and 5 are normal since according to the documentation, but in your case probably difference comes from country regulations.
Remember that 802.11ac is way more complicated (with BF, DFS) than 802.11n, so simple software analyzer may not be accurate.

Well, I set the country correctly, Netherlands in fact and I don't see much difference. Is there also difference between countries in the EU?

You can see the allowed channels and TX power with "country-info":

/interface wireless info country-info netherlands

It should show something like:

country: netherlands
  ranges: 2402-2482/b,g,gn20,gn40(20dBm)
          2417-2457/g-turbo(20dBm)
          5170-5250/a,an20,an40,ac20,ac40,ac80,ac160(20dBm)/passive
          5250-5330/a,an20,an40,ac20,ac40,ac80,ac160(23dBm)/passive
          5490-5710/a,an20,an40,ac20,ac40,ac80,ac160(27dBm)/passive
          5190-5310/a-turbo(20dBm)
          5180-5300/a-turbo(20dBm)
          5520-5680/a-turbo(27dBm)/passive
          5510-5670/a-turbo(27dBm)/passive
          902-927/b,g,g-turbo,gn20,gn40(30dBm)

As you can see, there are 3 parts to the 5GHz frequency band (for 802.11ac), each with different allowed TX power. These values are similar/the same in most European countries, as this is coordinated by ETSI.

Don't forget that if you're using the frequencies that allow higher TX power, you need to turn on radar detection:

/interface wireless set wlan2 dfs-mode=radar-detect frequency=auto

You can make sure your preferred frequencies are used by putting them in thescan-list for the interface (add several channels, so the AP has a frequency to move to if a radar is detected).

Turning DFS/radar detection on will lead to a downtime of a minute every time you change configuration of that interface, to do a new initial radar scan.

Hi guys,
I've just bought HAP AC instead of 750GL and I have some difficulties with configuring WiFi.
I have my home network like that:

Before HAP AC I used TpLINK Archer C7 (5Ghz AC Wifi) to connect my laptop with AzureWave AW-CE123H (5 Ghz AC 2*2) wifi card. It was connected to LAN5 and worked just as AP.
I test connection speed by copying file from my NAS via SMB.
When using Archec C7 I get about 330 mbps (laptop shows connection speed 667 mbps):

But when I using HAP AC as WiFi Access Point, I only have about 150 mbps (laptop shows connection speed 400 mbps):

WiFi config:

Quindor · Mon May 09, 2016 2:39 pm

I don't think it's so much an issue of a wrong configuration, but a difference in antenna configuration.

For starters the TP-LINK Archer C7 has external 5Dbi antenna's and the hAP AC has internal 1.5Dbi - 2.5Dbi antenna's. This means the TP-LINK will probably always have a bit better reception in similar conditions. But I suspect conditions are not similar.

The design of the antennas in the hAP AC means the antenna's are spread out in the chassis. If you just place it flat on a surface (like on a desk) that means there will be a big difference in reception to each antenna. This is fine with multiple clients around it but will not result in the greatest speeds with a single client.

Try temporarily mounting the hAP AC higher up on a wall or even better, on the ceiling. You will see big changes in throughput because the signals can now bounce a lot better through the room and reach your devices more easily. Admittedly the antenna design of the Archer C7 is easier when using it as a desk model.

For me that made the difference between ~250Mbit throughput and ~500Mbit with two wAP AC's in bridge mode.

Also, keep in mind that although the hAP AC can be used as a single access-point/firewall/router/etc. it's design is just more suited to being part of a whole (having multiple low power access-points throughout the building). I wrote a bit about this in my blog post: http://blog.quindorian.org/2016/02/revi ... great.html . If you are looking for a super high-power great antenna one AP device, the hAP AC isn't that. If you are looking for a good wireless contender with advanced features, even just as an AP it's pretty good (and very stable) but it really shines as port of a whole.

I'd like to have maximum speed in room with HAP AC. My laptop is about 3-4 meters from access point. And yes, my HAP AC mounted vertically - about 1 meter above the floor.

Hi guys,

I somehow can't get my hAP AC setup as a simple AP.

It is connected from eth1 to an ASUS router and I have set a static IP on the hAP AC.

I then disabled DHCP and NAT under Local Network and instantly loose connection to internet and the hAP AC.
Must both DHCP servers on router and hAP AC stay enabled? I thought only DHCP server should be active.
Or should eth1 be changed from WAN to LAN?

What am I doing wrong? It is always me I guess

I just want my wireless devices connected to the hAP AC be able to connect to internet and my NAS on on my home network.

Hello,

Just bought the hap ac and set it up as a router with wireless. I am measuring throughput speed on the internet connection and comparing it to a Sophos SG135 UTM with accesspoints (AP-55c) connected to it for wlan.

What should the throughput be on the HAP ac? I am measuring a maximum of 105-130 Mb/s outgoing, when my connection is a 500 Mb/s line. That is for wireless connections and also wired lan connections.

When I connect and run through the Sophos UTM I'm getting 400+ Mb/s wireless and around 480 Mb/s for the wired connection.

Network topology is exactly the same, except for the router/wlan devices obviously.

It seems that the HAP ac throughput is not up-to-par for this generation internet speeds.

It should easily achieve much higher speeds. What kind of configuration did you put in? In my tests (you can find here) it could do 1Gbit of NAT using fastpath/fasttrack without a problem? For a real internet speedtest it did 200Mbit (Max of my internet connection) with about 16% CPU usage.

Could you try with the queues and mangle rules disabled? Not saying you cannot use those, but depending on their configuration they can have a very big impact on performance. Try it with firewall and NAT only and see what speeds you get and then slowly re-enable to queues and mangle rules to see when it drops.

Ok, I did a complete reset and setup the MT with quicksettings as a Dual Home AP. So almost no (only basic) firewall etc. rules. My WAN connection has a downloadspeed of 500 Mb/s.

After that connected my macbook and ran speedtest with LAN and WLAN. LAN-speed around 450 Mb/s and WLAN around 150Mb/s on the HAP. On my Sophos UTM,etc. with full webfiltering, IPS, all bells and whistles, etc. LAN-speed around 485 Mb/s and WLAN around 395 Mb/s.

When I entered more firewall rules in the MT (no mangle, queues, etc.) the LAN-speed dropped to around 320 Mb/s and the WLAN-speed to around 115 Mb/s. When adding mangle rules, layer-7 and queues the speeds drop even further to below 150 Mb/s on LAN.

So this HAP is nice for lower speed/spec environments, but not up to the task for a serious home or SOHO AP in the Netherlands, where most WAN speed connections are higher then in most other places. I wouldn't recommend it for most SOHO and private users that need high speed connections for NAS, small server environments, gaming and/or more than 5-8 wlan devices in their homes.

Quindor · Sun May 29, 2016 11:48 pm

Odd that you are seeing such bad results. I will admit I'm not using a hAP AC as my router currently, but when I tried it worked fine. In testing it also did a Gigabit NAT (Maxed out CPU) between two LAN ports.

The features you are describing maybe aren't that common in a normal house though, but still. Especially the firewall rules really should have no effect on it whatsoever. My RB2011 was able to do 400Mbit with fasttrack and some firewall rules, only using queues and such did it slow down and the hAP AC has a more powerful processor then it does.

Did you also try some LAN - LAN tests? So between two ports, both in routed and switched mode? That might still be interesting to try. There has been a topic about the hAP AC becoming slow when hot, while I don't experience this myself it might be an explanation for what is going on? Running some iperf's with multiple sessions should suffice to find out.

I'm not quite sure why you are asking these questions, wireless in a mikrotik device works the same as with other vendors? If you are unfamiliar with wireless in general, this is most often the best way setting up wireless.

There is no "Best" setting really. It depends on your environment, placement of the AP and your client, type of client, etc.

Do an airscan and a frequency usage scan to see which channel can best be used and how much of the spectrum is still free. Be sure to pay attention to 20Mhz, 40Mhz or 80Mhz width. You can find charts about this online.

When performance testing, select a free 80Mhz band and test with your devices. 80Mhz will give you the best throughput, but choosing 40Mhz or even 20Mhz is sometimes preferably when the spectrum is "dirty" or when range is more important then throughput.

And that should be it. With that said you should achieve the best wireless performance.

What I did notice is that trying to place the access-point most optimally can defintly help with the signal. Make sure there are no big objects blocking the line of sight to your device. Or, if there are walls and such in between the path to minimize that as much as possible. Things like reinforced concrete or an aquarium or even a big flat screen TV can really kill you signal. Also try mounting the access-point to the ceiling or high up on the wall so the signal can spread around and bounce freely. Lots of variables to consider!

Hello, today i disccovered strange fault with both my hAP ac units:
2.4 GHz radio doesn't work on higher channels and both units show different "stage" of this behaviour.

The first unit works fine only if I select 20Mhz and channel 1. If I select for example channel 6 or even 11 I am not able to connect to it (or it connect very unstable) with my laptop and phone. If I set 40Mhz it works badly (because it uses higher extension channel)

Second unit works fine on channels 1 and also 6 but doesn't work on higher (11).
40Mhz works fine if set to channel 1.

I am not 100% sure but I think both units worked fine the day I bought them - but lately I had issues with wifi so I investigated this issue.

What is wrong with this? It is not interference- i checked with spectral scan and even took it to different location and it behaves identically. Also I don't think it is problem with other devices - I replaced it with 951G and it works fine over whole frequency range with both devices.

dkalam · Sat Jun 18, 2016 10:28 pm

Same behaviour as mine... Only works in channel 1 with 20 Mhz. ROS 6.35.4 with cm2 although i still get strange lock ups in random times.

5ghz works perfectly..

Atlantis · Sat Jun 18, 2016 11:21 pm

Are you going to RMA? I will at least one unit - it is not cheap device to be this shitty!
I did some modifications to second unit because of low tolerance to USB capacitive load (http://forum.mikrotik.com/viewtopic.php?f=3&t=106174 ). But fortunatelly the second one works at 40Mhz (but only on 1st channel)
Mikrotik really disappointed me - this fault, USB problem, LAN switch problem (as I read here in topic...)

gramels · Sun Jun 19, 2016 8:09 am

did you try channel 12 and 13?
may be change country settings to test?
I sit the channel restrictes US version or the international one?

Atlantis · Sun Jun 19, 2016 12:16 pm

I have international unit. I did change country but with no effect - it looks like HW problem.
I have connected the less affected unit and tried this again with all channels. It works on 1 - 6 but on 7-13 I am not able to connect. Sometimes it shows "connected" in mikrotik log but few seconds later it disconnects. It acts like you have very poor signal or extreme interference.

I even tried different chains setup at problematic channels:
with chains 0+1+2 I am not able to connect
with only chain 0 it works but only few Mb/s
with only chain 1 it works but only few Mb/s
with only chain 2 I am able to connect but works as badly, I am not able to complete speedtest.

with chain 0+1 or 0+2 I am not able to connect.
And with configuration 1+2 I don't even see the network in other devices!

And yes, both chains are Tx+Rx and Yes, with single chain I saw the network on all chains and yes, I check on both devices and even after 1minute I don't see the network! Quite mystery...

Hi, guys
I received my 2 HAP AC few days ago, did some test. I have 200Mbps/20Mbps at home, which was supported by netgear R7000(uTorrent download get around 25MB) But after everything i tried, my new HAP AC still can't exceed 125 Mbps, which is not acceptable for me. Everytime I test on speedtest, CPU always reachs 100%.Someone in this thread mentioned it can handle 300Mbps NAT. I'm starting to think it should be hardware issue, health indicates 23.8V voltage and 58 C. Here is my configurations.

Anybody prove me he can exceed 250Mbps NAT should also prove that I need RMA this HAP AC
Thank you very much, excuse me for my poor English.

kenyloveg · Mon Jul 11, 2016 1:53 pm

Well, i did some verifying and report back here.
1. Replaced another HAP AC(when temp indicates 36C) with same configuration, still the same results
2. Replaced HAP AC with RB951G, NAT speed down to 106Mbps, but after manually enable fast track, it goes up to 130Mbps

/ip firewall filter
add chain=forward action=fasttrack-connection connection-state=established,related
add chain=forward action=accept connection-state=established,related
add chain=forward action=drop connection-state=invalid

3. Fast track does not work on HAP AC(whatever fast track checked or not in /ip firewall connections), speedtest still keeps up to 126Mbps
4. Changed WAN port from ether1 to ether2, still the same
5. Changed packages from 6.35.4 to 6.36rc37, do reset and no default config, import same configuration, still the same poor 126Mbps results.

Most likely, the root cause should be fast track/path was broken on HAP AC.
Any comment?
Thanks

Mine is working just fine.

1) what interfaces are involved in testing? Ip pppoe make sure that you have version that have pppoe fastpath support added, if wireless make sure that you are running proper wireless package.

2) do you see fastpath counters counting?

1. pppoe client use ether2 to dial out, Bridged ether3, wlan1,wlan2, fast track is checked, test was always through ether3 (even i directly plug ether2 to desktop pc still the same)
2. yes
Even fast track is chekced, the NAT speed are exactly the same when it is not enabled. If a performance feature has no improve on performance, what's the meaning of enabled or not?
Did your HAP AC can exceed 200Mbps NAT?
Thanks.

1) with pppoe you need RouterOS version at least 6.35, and make sure that there are no encryption.

2) in /ip settings and /bridge settings, and in /ip firewall connection there are fastpath and fasttrack counters.

I can run all 500Mbps that i have at home getting only ~60% load, but i can reach those speeds only while torrenting. and i chronically dislike speedtest .

Hi, macgaiver
What encryption you mean? Those mschap/pap/... under pppoe client settings?

Mon Jul 11, 2016 3:36 pm

Hi, macgaiver

Hi, macgaiver

Would you post your exported configuration? I go check these settings soon.
Thanks

kenyloveg · Mon Jul 11, 2016 6:29 pm

Hi, guys
The NAT performance reaches 220Mbps (which is my FTTH) finally, after i attached HAP AC to my old netgear R7000's lan port, use quickset to automatic get DHCP IP address from R7000.
That proves the NAT performance isn't limited to 120Mbps. CPU hit around 75% when fast track disabled, and around 35% when fast track enabled, this is really good form me.
Then question comes to my pppoe client configurations, i've no idea where is wrong. Would anyone post your pppoe client configuration?
Thanks.

I'm having trouble getting anything above 320/330 Mbps over WiFi from hAP ac , this is with a 80MHz 2x2 client.

Has anyone had better luck?

Mon Jul 11, 2016 10:38 pm

I'm having trouble getting anything above 320/330 Mbps over WiFi from hAP ac , this is with a 80MHz 2x2 client.

How do you test? Have you tested what speed can be achieved over cable?

risk · Tue Jul 12, 2016 12:35 am

How do you test? Have you tested what speed can be achieved over cable?

Serving data over a single http/tcp connection from a really simple http server I wrote in go, that's running on my tiny old hp n40l and serving a random block of bytes in a loop to my 2015 chromebook pixel ls.
hAP ac has a bridge between ether1 and wlan2 and as of a few seconds ago gets me 345 Mbps over WiFi (lucky I guess).
When I take the cable out of ether1 and connect the that chromebook using usb-c <-> ethernet and repeat the test I get 111MB/s / 935Mbps.

Edit: despite my DIY testing setup (I have to test in a browser), my question still stands, ie. Did anyone ever get more than 320/350 mbps tcp over 2x2 802.11ac WiFi on a hAP ac in any conditions. The reason I'm asking is that apparently in tp-link devices and in dd-wrt firmware the QCA9880 is somehow capable of it (and I've seen 700/800 mbps wifi with 3x3 with other chips), which leads me to believe something must be wrong with my hAP ac units or maybe I just can't find a good ros version to run on a hAP ac.
Also, when I configure the wlan2 for 40MHz 802.11n I get a bit more than 200mbps in with my testing setup. 802.11ac has 33% more efficient encoding, and the channel width is 80MHz and so I'd expect to get ~500 mbps instead of ~320 - ~350 mbps

sstyle · Fri Jul 15, 2016 9:51 am

Performance with my Macbook pro 2015 = 1300 Mbit/sec:

But I hope it can be better, because I get this connection speed with stock settings (Changed channel width only, and country set to Taiwan)

sstyle · Fri Jul 15, 2016 9:52 am

Little differences between 2.4 and 5 are normal since according to the documentation, but in your case probably difference comes from country regulations.
Remember that 802.11ac is way more complicated (with BF, DFS) than 802.11n, so simple software analyzer may not be accurate.

What is it BF? Which country settings is better? I need maximum perfomance and signal strength

2. You are using latest Firmware version;

3. You have enabled wireless-cm2/wireless-rep package;

How to check current Firmware? I see 6.35.4 but is not fw ver as I understand, it is RouterOS
What is better cm2 or fp for apple devices? What is it wireless-rep?

Zorro · Fri Jul 15, 2016 10:52 am

What is better cm2 or fp for apple devices? What is it wireless-rep?

FP package was deprecated and not supported anymore.
in theory "Ultimate" was rep, especially if you need its major new features, otherwise you can save bits of resources(some speculated that it somewhat more loading RAM and CPU, but difference is quite marginal/tiny to bother about).

Fri Jul 15, 2016 11:13 am

wireless -> FP -> cm2 -> rep -> wireless

Hello,

Please help me.
I have rb952ui-5ac2nD.
A would like test routeros downgrade. But router is brick.
Download mipsbe5.26, and click downgrade.
Router reboot, and not respond.
Situation:
When not responded 30 minutes I reboot. Until reboot power and usr blink no other (1-2-3-4-5 if lan cable pluged, not blink).
I try netinstall 6.35.4, but not work.
I disable Windows7 firewall and setting notebook IP 10.1.1.10 Nm:255.255.255.0.
Netinstall setting: boot server enabled, client ip 10.1.1.5.
And press the router reset button 30second, but not work, netinstall is can not see the router.

Winbox can not see a router.

What is wrong?
Help me!
Thanks

sasbibic · Sun Jul 17, 2016 3:19 pm

Try to disable all but ethernet network interface,before using netinstall.

Very strange issue. I have a iPhone SE, Macbook Pro 2015 and iPad mini 2. Macbook and iPhone initiate connection to WIFI very fast. But when I turn on iPad it does not connect to wifi first 30 seconds and then connect to wifi (2.4kHz). How to fix that? WMM enabled, channel set to 20Hz, preamble set to long.

sstyle · Tue Jul 19, 2016 2:13 pm

You can prvovide iperf command with intresting for you params, I will do these tests
@alber you are awesome! Thank you very much for all your answers! :D

I always use iperf2 from https://iperf.fr/iperf-download.php, if you want you can use iperf3 too but the command line switches are a bit different.

If you are using iperf (2) then use the following settings please:
server: "iperf -s -w 1MB"

1 Channel
client: "iperf -c xxx.xxx.xxx.xxx -w 1MB -R -P 1 -t 30"

4 Channels
client: "iperf -c xxx.xxx.xxx.xxx -w 1MB -R -P 4 -t 30"

16 Channels
client: "iperf -c xxx.xxx.xxx.xxx -w 1MB -R -P 16 -t 30"

A second set (if you are willing):
server: "iperf -s -w 64KB"

1 Channel
client: "iperf -c xxx.xxx.xxx.xxx -w 64KB -R -P 1 -t 30"

4 Channels
client: "iperf -c xxx.xxx.xxx.xxx -w 64KB -R -P 4 -t 30"

16 Channels
client: "iperf -c xxx.xxx.xxx.xxx -w 64KB -R -P 16 -t 30"

That should give us a good overview of total bandwidth attainable using one stream and multiple streams both using large block sizes and small.

Hello,

Please help me.
I have rb952ui-5ac2nD.
A would like test routeros downgrade. But router is brick.
Download mipsbe5.26, and click downgrade.
Router reboot, and not respond.
Situation:
When not responded 30 minutes I reboot. Until reboot power and usr blink no other (1-2-3-4-5 if lan cable pluged, not blink).
I try netinstall 6.35.4, but not work.
I disable Windows7 firewall and setting notebook IP 10.1.1.10 Nm:255.255.255.0.
Netinstall setting: boot server enabled, client ip 10.1.1.5.
And press the router reset button 30second, but not work, netinstall is can not see the router.

Winbox can not see a router.

What is wrong?
Help me!
Thanks

Did you try to netinstall on eth1 ?
Also, are you sure you are doin it right ?

Is it possible to disable all leds? I see a disko-light on the wall (

ka4opi4a · Thu Jul 21, 2016 6:18 pm

I think you can disable all but power led.
Go to: System/LEDs

Try to add interface and then disable it.

i have also one only working on channel 1 with 20 mhz ...

Same problem here.
Connection on 2,4Ghz radio only possible on channel 1, 20Mhz.

Is problem with wifi solved or at least added to bug tracker? Going to buy hAP AC, now have 2 RB951, RB912UAG, hAP lite.
Wifi is very important in both ranges because of of many legacy devices.

We bought 5 new HAP ACs for testing last week and are having huge wifi issues with them.
LAN/Ethernet performance is flawless but WiFi speeds are incredibly bad in for 11n and 11ac.
Even with a 1m distance to the routers, we get 2/10mbits (down/up) on 11n and 8/30mbits on 11ac.
We are using the same CAPsMAN setup we have been using with a lot of other mikrotik devices, including wap ac and hap ac lite. CAPsMAN shows negotiated speeds of 800Mps+ (3 chains) in the registration table for some devices. All 3 we have tested so far are showing the same behaviour. All are upgraded to the newest RouterOS 3.36 and have wireless-rep installed.
Any idea what the issue could be?

Not sure if I'm reading this right, your solution was to replace all HAP ACs with old RB951 and not use the HAP ACs at all?

Mon Aug 15, 2016 8:39 pm

Yes...but It is not final situation... however the point are problems not the soloution

Update: Without CAPsMAN, wifi speeds are much, much better! I configured the wireless Interfaces on one of the HAP ACs directly without using CAPsMAN and now wifi speeds are up to 70/70Mbps+ for 11n and 280/280Mbps+ for 11ac.
It seems that CAPsMAN with local forwarding is causing a lot of issues. Maybe CAPsMAN is not configuring HAP ACs correctly?

I have 19 HAP AC's and on none of them it is possible to get the 2.4 ghz working correctly ...

- i did also lower the tx power, still not working

if you use central forwarding with capsman, the router must re-encapsulate all data to be able to send to the controller.
now the thing is, that it hurts 2-3x more as it should:

say you have a pretty normal 1500 byte IP packet.
depending on how capwap is implemented the packet will have a 802.11 or 802.3 frame around it. i suspect the latter one, which then with all the ethernet headers will be 1514 or 1518 (depending whether you use VLANs or stuff like that).

then all those headers add together as capwap data is being encapsulated into udp and then ip:

- IP Header (assuming 20 bytes) - in case of ipv6 it's 40 bytes.
- UDP Header (8 Bytes)
- CAPWAP Header (8 - 16 Bytes)

The CAPWAP payload contains the original wireless frame / or 1 ethernet frame
- 802.11 Header (24 Bytes) / 802.3 header (14-18 bytes)
- Original IP packet (1500 Bytes)

so after the math have been done, you'll end up somewhere at 1550-1588 bytes, which definitely will not fit into the regular 1500byte IP MTU.
that is, after encapsulation you have to fragment the packet and of course reassemble on the other end [pain on the controller side]. fragmentation itself is a cpu intensive stuff,
and as the packet will be cut in 2 halves, your PPS will be also halved, which will cause a notable degradation in forwarding speed.

there are things to work this around, but not everything is under your control:
- use jumbo/baby giant frames on the uplink [you may not have support for it in your backbone]
- lower the MTU on the wireless side and use tcp mss adjustment to make tcp payload smaller so the whole encapsulated traffic including capwap magic
fits into 1500 bytes. udp will still suffer and may be dropped if MTUs does not match on client & ap.

life's hard.

Are you passing by any firewall filters? Try enabling fasttrack for that connection.

I noticed a new firmware upgrade is out now for the hap ac, 3.34. I've just upgraded, anyone see the changelog?

Usually those RouterBOOT updates are just "additional device support" (to make it work on new hardware revisions etc.).

Once Mikrotik updates it, the change log should be available here: http://wiki.mikrotik.com/wiki/RouterBOOT_changelog

Guys, please add a new feature - completely disable all leds (power led can be enabled). It is very difficult to sleep with disco-light on the roof.

Just apply black tape on them.
