You don't need any CVE for that. Please re-read the original post. In theory you could even take the router apart and re-solder some chips on it. What is the point calling such situations "vulnerabilities"? If your device has full admin access to malicious parties, ALL IS LOST already Cou...

Lupin

What a pity

Furthermore, as already mentioned in other topics, not supporting these standards means not to be WiFi4EU compliant.
Mikrotik some planning date?

Lupin

I see MPTCP implemented using OpenWRT on end Router, and a debian/ubuntu on datacenter vps
Creating some tunnel make real aggregation of multiple ISP with different bandwidth, latency instantly

See this example:

Lupin

Mikrotik, with the new kernel do you think to make MPTCP available?

Lupin

What is the Mikrotik's opinion?

Normis, Uldis ? tell us something

Lupin

Dear Mikrotik team,
Please review a possibility to provide a full featured Web access support to the Dude.

Yes! We need them back
This is the main reason why we are still using 4.0b3

Lupin

I doubt MT would spend the time and money developing it.

Do you think it's not an interesting market for Mikrotik?

Lupin

How do you mean? Like a PBX?

Yes, a PBX.
Initially similar like a FritzBox, in future powerfull like an Asterisk PBX

Probably they will already have asked for it in the past, but I want to reformulate the question: are you going to develop a VoIP package? have you evere thought?

Lupin

Have you find a solution? Are you sure that the 1016's themselves are the cause of the loss, and not the intervening connectivity? In general, loss is associated either with a single core being maxed out or close to maxed out (90% or higher), or congestion. See the video https://youtu.be/Mrr6Ubh8hW4

Lupin

What speedtest, exactly?

Not more than 20Mbps (speedtest.net)

Lupin

What do you do with removed switches?

Nothing.. it remain on shelf gathering dust

Lupin

The point is not to change the hardware,
(I have about 60 CRS to remove and I'm already doing it) but understand if the slowness is due to some system bug, and if it is, correct it.
I would have a little more time also to buy and change all the hardware (unless then, the problem is not fixed)

Hi,

when there is too much clients on NV2 sector you have to use larger TDMA Period to achieve good throughput. It of course means that ping time goes higher.

On all my APs increase the tdma period doesn't benefit nothing.

A single chain cpe eats up to double the airtime compared to a dual chain cpe. If it is a bad performer due to bad conditions it slows down the sector.

I think that my problem are NV2 related ?

draguzet this is a typical problem that I've in NV2 PTMP.
It should not happen, or impact so strongly because of the nature of TDMA, but in Mikrotik anything could happen

I think Mikrotik is opening to the market of home network.

In the last newsletter (67) we see a photo of new product (sector) but is not mentioned into it

I agree, Mikrotik not longer consider WISPs market.

Lupin

With AC-Radios work only with "all rates fixed" but your main problem is alignment

If your link is with perfect line of sight (and free fresnel zone) then they are just bad aligned

Make correct alignment and see (using the default tx power) what you get

Lupin

Yes,
remove all wds configuration and use the mode=station-bridge on all clients

Lupin

try to setup a 20/40Mhz channel, set the rts/cts, distance to indoor, enable the Wireless-fp package.
Update to 6.28 with last firmware

and check again

Lupin

you can user userman to setup an account and limit per 30minutes per day

Lupin

Yes this works fine but remember:

ubnt Sector has electrical downtilt
sxt work to max 3-4km distance
you need perfect LOS for all users
how bandwith-rate you want to offer to clients?
you must use nv2

Lupin

In the last two rows remove the
mac-address=00:00:00:00:00:00

and try it

Lupin

You can try creating Channels manually
Wireless > Channels

Lupin

If you have default tx power then you need to better align antenna

On 10km your signal should have at least -40 or better

Lupin

"wireless - improve ac radio coexistence with other wireless clients" - what does it mean exactly?

What exactly did you improve?
Improve performance or latency when both N and AC clients are connected?

It also improves with Nstreme and NV2 protocol?

How much?

I don't know others, but wireless market of Wisp is ever expanding and increasingly, better tools are needed in order to compete against "enemies".

Please give me good news

Lupin

ok, but with the tdma protocol we could give a determinate amount of time/utilization to prevent this behaviour.
if only there was an option to set it

Lupin

I have a sector (RBMetal +Panel 23 db) with 16 clients connected on my BTS. One of the customers connected with a -73/-69 dBm to 8km (groove52HPn + 29dB grid) has a download bandwidth of about 3-5Mbps (BWTest UDP). Another customer connected with a -53/-52 dBm get to about 30-32Mbps (BWTest UDP) Whe...

Improve throughput / latency? It solves some stalemate? Can we try it? If so, where is the download...

Lupin

2-3km with a 29dB antenna? and you have only -62/-62 ?
Is too low. there are bad pointings or obstacles

I expect at least -45dB

Lupin

Strange behaviour!!

With your configuration the station must connect only to an AP with
mac-address=54:78:1A:64:31:71 AND ssid=concoursep AND security=yourWpa

If the station connects to others APs then, other AP has at least a mac cloned

Lupin

Sure that your device (notebook/ipad...or whatelse) can connect in band of 5Ghz?

Or are only 2Ghz?

Lupin

I forgot to add the functionality of the Wireless Controller Wireless Controller feature allows to centralize wireless network management and data processing Mikrotik has already drafted the technical specifications http://wiki.mikrotik.com/wiki/Manual:Wireless_Controller I add it to the list 8)

Lupin

should be add
link load and nv2/nstreme capacity info in %

You mean, to see the real capacity of the wireless link and the percentage of its use?

For example:
Link Rx/Tx Max Capacity: 98Mbps/33Mbps
Link Rx/Tx Actual Load: 49Mbps/11Mbps
Link Rx/Tx Actual Load %: 50%/33%

Advanced Scanning : Scans all visible proprietary APs and for each (respecting SSID, security settings, connect lists, etc.) connects and keeps track of the SNR, Rx/Tx signal strength, radioName, mac-address and distance.

Lupin

things you can do already: 1) adjust scan list - enter frequencies only intended for the site, like 2 - 4 channels - super-fast reconnect even on 5GHz band 2) adjust access list rules on AP, there you can set minimal and maximal signal strength that is allowed to connect. On client RouterOS you can...

It allows cpes to send at the same frequency at the same time. So it increases capacity. it looks the same thing of GPS Sync :( I have to take a look at some explanation of this technology I have no 450.

Maybe also frequency usage scan to file

On my point one.. there are already these requests

Lupin

Normis, "QRT G" is a dual pool antenna?

It would be perfect in a "23dB" "5Ghz" version. Is that possible?

Lupin

I update the first post with some of your suggestions

If I have not understood well, correct me

Lupin

You mean an attenuator on the 5Ghz frequency (the ones where you work normally) or attenuation larger or smaller 5Ghz frequency (or the specified range)

I believe that an attenuator lowers the input power and also output when used on the range of operating frequencies... you give an example

Lupin

Have you plans for the next version some NV2 improvements?

Hi honzam if you want wireless improvements from Mikrotik please add your opinion, or your interest in this topic

I am happy that someone posts his ideas. thanks ejansson. :D We try to understand your points: 1) Have client/remote start scanning on last used frequency or simply in the the frequency setting in the client/remote as a starting point. This would speed up reconnects a lot particularly with 5ghz wher...

All good ideas.

I haven't tried it yet, but I was thinking about using WDS to sync as a work around.

It seems that the " connect-list " has lower priority than Wireless Protocol and this causes problems. All my cells have the same SSID. In the example below the sextant, after a reboot, it connects to the cell with NV2 protocol (22:22) despite the long distance and poor signal and there IS...

Lupin

I see that Sextant have already a predisposition for external N-type connectors. It's important for connect a dual-chain dish antennas in a long distance client situation. But for do this we have to manually drill the plastic case. There are any plans to release a pre-connettorizzed version of this ...

File save feature was created, but we have not created software to read these
files. Currently you can't do anything with it.

Offset reflectors are working very good. 10dbi more with 55cm. I tried a RB711 + Grid 90cm x 60cm vs SXT + Offset 60cm On the same AP cell with the Offset+SXT I got 3dB less than the other. I thought that would make something better of the grid. Probably would be better with a 5Ghz real feeder ? SX...

Lupin

I think the product is fine.
SXT Reflectors!

We have already tryed to use offset but the result was not acceptable

why can't you use RB711 in a box and any antenna you choose?

Because with the RB711 and the box there's still much more to assemble and the rb711 isn't MiMo 2x2

Lupin

The RB-SXT would be an excellent product to be used in multipoint because 1 - There's nothing to assemble (it is ready to use) 2 - It has built-in LED signal for easy alignment 3 - It have MiMO 2x2 and this maximizes spectral efficiency 4 - Very practical The problem is the LOW GAIN !! :( Now, I ask...
