Hello.
I’m new to MikroTik. I just bought MikroTik hAP ac2. I really love all the features it offers, it's amazing but I can’t find out what’s the problem with my WiFi. I replaced my 8 year old tplink N standard router (DDWRT) but download speed is even worse with both N and AC. Upload is great though.
I updated my router to 6.41.3 (including fw). That didn’t help. I tried to change a lot of different WiFi adapter settings, nothing helps.
Here is my speedtest results with AC:

Sometimes I get up to 40Mbps download but that’s max. Upload every time is at least 100Mbps. I tried to test my speed with a few different devices. Same thing.
Wired I’m getting 500/500Mbps or more.

Currently my Wireless config is: I tried a few different configs that I found here… Changing channel-width, rates disabling firewall didn't help. Any suggestions?
Other than WiFi I really love this device…Honestly, I'm surprised with SMB performance. I didn't expect it to be any good but so far it rocks!

That is very weird.

Thinking about it, that sounds likely to be caused by some setting issue, likely in the wireless protocol settings.

Its unlikely to be the antenna. That said, here are my thoughts on the antenna for one unit I saw. It could be improved if there was more space in the vertical direction available.

I don't know if its the same unit that I saw in another thread but there was one where the internal antennas were constrained to fit into the box. They were small metal curly-cues in the corner of the device. I would experiment with opening it up and seeing if they could be extended a bit, so the loop enclosed more space upward. So as to be more like a pigs tail and less like a box. (But not so much that it could not be restored to its previous position if the change was not helpful.)

"Just sayin" They might be dealing with insanely restrictive national regulatory regimes which require they make all sorts of illogical changes. They likely couldn't explain that here, this being their official organ. But if you met them in real life they could likely be more candid.

Note, that is just my personal guess.

Whatever it is, I doubt if its their fault. I'm sure they know what they are doing.

Did you test without wireless security?

Same problem is in hap ac lite. It justifies each other differently. Just do not use the mikrotik as a home appliance.

Turn off auto frequency. Try set it to e.g. 36 channel.

my hap ac lite and LG 55UJ635V (5 meters distance):
connected to 5hgz (ac) can't reach more ~ 10mbps
connected to 5hgz (n) can't reach more ~ 40mbps
connected to 2hgz (n) can't reach more ~ 30mbps
and very very unstable, even can't flawless play FHD videos.
Connected wired and got my 100mbps. Other wireless clients works fine.

True if you don't know completely what you are doing. Otherwise, the device is great!

@TS: I have very good results by setting security to AES (and not TKIP, not sure what you used...). And (ofcourse) fixed channels!

Same problem here. hAP ac^2 wireless down speed ~10-20mbit/s on both interfaces(802.11n 2.4Ghz && 802.11ac 5GHz), and upload ~100mbit/s constantly.
Fixed channel, playing with tx power, country regulation, encryption, hw retries, etc didn't help.

I tried almost everything, nothing helped. Then I tried newest RC firmware. I saw incrase in WiFi download speed immediately. I guess that there are no stable FW with fixed WiFi on Ac^2 out there yet. But I'm glad that this problem is fixed on RC fw.

1. Could you please tell me what is the final download speed value?
2. Which RC firmware that you have used?

Thanks in advance.

Do you now get full DL/UL speed?

I am seeing the same issue with my hAP ac^2.
Wireless interface seems to grind to a halt with minimal amount of traffic. It suffered from significant packet loss and latency spikes.
With the current stable firmware the download speed was spikey at best, and often flat lining at 0.

6.42rc49 seemed to have improved the situation, there seemed to be some throughput fluctuations, however the latency spikes seems to be much better.
Can't wait for the stable release to arrive!

I have the same problems with hAP AC^2. I have 100Mb/s internet channel and upload rate was initially around 94Mb/s (it seems like using the full channel), but download rate on 6.41.3 was very poor: 10-15Mb/s. After upgrading to 6.42rc49 download rate significantly increased, but it's not stable and bounces around 65-75Mb/s, even in 1m from the router .At the same time I see Tx Rate: 400Mbps (sometimes 800) in Wi-Fi info:
I am very disappointed, because the purpose of buying new device was to get full benefits of 802.11ac standard.

P.S. And I've tried different channels and modes, without any significant impact.

Hello , just got my new hp ac2 and i was using before hap ac, so first impression.. wifi very unstable i upgraded to 6.42rc52 and i got a slow connection on 5Ghz AC.
Settings are : Frequency - auto , BAND 5ghz-only-ac , 20/40/80 Ceee. My current bandwidth from ISP is 300 mbits Download and 150 Upload . On my Samsung S8 i have somewhere around 230 mbits download but on my desktop with intel dual band ac 7265 , distance to router is about 4 meters open air. On hap AC with latest stable firmware everything runs ok . Any suggetions ?

same here! Pretty disapointed with wireless part of router. I have 100/20 connection and router gets from 55-75(very fluctuating) in download and 20 in upload. Router is 4m from PC. With Speedport router(ISP) on ame place I can get around 135/26. I am just disapointed with wireless part of HAP AC2...

I had the same problem. Upgraded to 6.42rc52, and get acceptable WiFi throughput. But now I am experiencing complete WiFi blackouts at 5Ghz in some irregular basis. It can be for 10 seconds after some 30 minutes, sometimes for 1 minute and more. The feeling is like somebody would run jammer at 5Ghz. Wait for few minutes, and like nothing happened and throughput is good in both directions.
I tried everything, Channel width, channels, WiFi standatrs, even tryed to leave only old A standart. Exactly the same behavior.

The same issue from my end. I was able to install the latest RC 6.42rc52, but download speed is unstable and poor.
Upload is fine and stable enough.
I just got the AC2 and I am disappointed from the speed provided. I am wondering what is the policy of the vendor. Can be replace it with another one?
This is the worst Router device I have ever owned, considering the download speed.

I had the same problem with most of post. My download and upload speed are both very low. Trying use RC version.

Has anybody new experience with the device?

The 5GHz on hAP ac^2 has already been resolved since v6.53rc5.

For details, take a look at the following link:

For test environment yes,
For production environment not yet.
We can't use an RC software in production.

Hi, all
Recently bought hAP ac2, it turned out a nightmare to get stable fast link on 2.4 radio.
Options tried:
manual channel select
security (aes/tkip/none)
channel widths with different options (Ce/cE/XX)
updating to RC firmware/OS
leaving only N/a/b/g mode
setting transmit power
power source change
There are few APs from neighbours, however there are 2-3 usable channels, where speed seems to be better, but its still slower than cheap tp-link.
I've got only 15-35 mbps on torrent download comparing to 45-55 mbps on tp-link.
Local share is even worse, transfering file from PC to android and vice versa is only 12-18 mbps vs 22-28 mbps on tp-link.
MikroTik's btest shows 100mbps on 'clean' channels in both directions (separate tests, duplex going 100 for download, 3.5-4 for upload), but internet speed and actual transfer speed is much lower.
Wired im able to get 100 mbps, so its not ISP issue.
My network is laptop (some realtek card), desktop (tp-link wl-721N usb adapter), both are capable of 300 mbps (at least it is indicated in connection properties and in other router status) and 40 MHz wifth, and Redmi3S (20 MHz width)
Am i missing something important?

Hi,
I also suffer from very low download speed on Wifi (both 2,4 and 5 GHz).
I havn't any special configuration - man can assume, that i'm using fabric preconfigured Hap Ac2.
I bought Mikrotik mainly to have strong home AP.
My ISP max speed: 60 mbps
Laptop WiFI card: Intel AC 3165 (dell laptop).
my measurment:
wifi (both 2,4 and 5 GHz): download max 17mbps
wired - download 60 mbps (max isp speed)
I connected my NAS to mikrotik (cable) and copying file from NAS to laptop (by WiFi) in TotalCommander shows near 11,5 MB/s - so its near 90mbps!
curret software ver: 6.43rc56
I'm not network specialist but for me its Wan<-> WIFI Lan problem. But haven't enough knowledge to confgure this Mikrotik properly... I was hoping, that "preconfigured" Hap Ac2 would work well for my simple needs
I would be gratefull for any suggestion.

PS: the worst was when i did some tests with cheapest router tplink wr841n and got full 60mbps on wifi....

I have checked my Wi-Fi speed.

90 Mbit/s on 5 GHz wi-fi. The same on notebook (Dell 3576) and Xiaomi Redmi 5 Plus.
This is the limit of my ISP by wire.

Firmw. 6.42.7

My wlan settings:

Band: 5GHz-A/N/AC
Channel width: 20/40/80MHz Ceee
Frequency: auto
Scan list: default
Wirless Protocol: 802.11
Freq. Mode: superchannel
Country: no_country_set
Antenna Gain: 0
WMM supp.: disabled
Bridge Mode: enabled


HT tab: Tx/Rx chains all four checked.

Nstreme tab: all checkboxes unchecked.

WDS disabled.

Any solutions? I have the same problem, with the latest firmware.

This looks like standard radar detection. Activate logging and verify.

I had the exact behavior today, download around ~15Mbps and upload ~200Mbps, other devices could reach higher speeds.
Router hap ac 2 and device was macbook air with windows 10, broadcom ac wifi card.
I fixed it by replacing my current wifi driver on windows (was 2019/10/10) with the one from Apple BootCamp (driver dated 2015), now it works ~350/350Mbps.

I had a hap ac2 for over a year, had literally 0 issues. My friend wanted a replacement for his generic Asus router (just a home AP) becuase it became so hot that it died. Of course he got a hap ac2.
I had literally the same issue: proper upload speeds, terrible download speed.
I brought that home to check if it's a faulty one or what, and suprise: 160Mb up-down on 5G wifi.
Do you have an IPTV at home? I think that's the issue here. His set top boksz makes some traffic even when it's on standby!
I found that IGMP snooping may be the key, he will get back his router maybe tomorrow. I enabled IGMP snooping on the bridge interface, maybe it helps!

I set my 5ghz interface to BAND: 5GHZ-N/AN and CHANEL WIDTH 20/40/80mhz xxxx and got full speed on my 100 mbps d/l and 20 mbps u/l.
I hope that this will help someone.

Thank you.

IGMP snooping can fix it being a solution that solves the true problem.

The problem is your equipment has a lot of data and don't know what to do. So it does what it thinks the best for that configuration.
Example: IPTV traffic folding WLAN radio card to emit all the traffic to all the wifi user.

What happening is in real life happening:
First, when updating the firmware some new configuration changes giving a solution to the problem.
Second is configure the bridge to handle the traffic on the way we want. IGMP snooping can do it

Using a different network topology can do the same. Using firewall rules, use L2 layer rules, etc...

My case, 6.7 Mbits from IPTV sent to the wifi radios, solution IGMP active that controls the bridge. I disable to be sure Fast Forwarding too.

I hope I helped
