Hello, I have MikroTik RB952Ui-5ac2nD (hAP AC Lite) and 100 mbit/s internet connection.
Here is speed test results:
2.4 Ghz, ~1 m from router:
5 Ghz, ~1 m from router:
Ethernet:
As you can see, download speed on wireless connections is 2 times slower than upload. Does anybody know the reason of this issue and how it can be fixed?
Please post your config. What is CPU status when you testing speed. I get 300Mbps on my hAP AC.

Sorry very late answer but try this. I fix my speed issue force only 54Mbps rate or force only AC.
I have exactly the same issue and configuring rates doesn’t help. Does anyone know what could be the problem?
will it because 2.4G using 1.5dbi Antenna and 5G using 2dbi antenna ?
My hap ac lite 2.4G wireless perform bad as well.
Tried different channels?
What is your connection speed, CCQ, etc?
Wireless speed/distance depends on client devices as well. For example : You can’t expect 450Mbit rate on 2.4GHz client device with only one chain 20MHz radio. Please provide more information about client devices as well or try running simultaneous speed tests on more then 1 device at same time.
A valid question, AntonsB, but regardless of his client, he’s getting almost exactly half the download speed vs the upload speed. That suggests something strange is going on.
My money is on it being an Intel single chain AC card.
Anyone want to take bets? lol
i change channel and width from 20/40mhz to 20mhz only due to quite far from AP as well..
now get better CCQ
Hello Anton,
we have exactly same issues with hAP AC lite. Download is half of upload speed.
We tested with 2 cell phones (Apple IPhone 6S & Huawei P9) and 2 laptops HP Probook 6560b.
Distance 1m from AP.
100 Mbps internet.
Only 1 client connected - 200 Mbps-40 Mhz/1S/SGI - 200 Mbps-40 Mhz/1S/SGI
42 Mbps download / 90 Mbps upload
With 2 clients speed gets halved (shared) on both clients. So 21 / 45 Mbps.
No matter what we do same results.
CPU on download: 55 %
CPU on upload: 82 %
Configuration:
/interface wireless
set [ find default-name=wlan1 ] name=wlan1/2.4Ghz

What firmware version for your hAP AC? Please try the latest Bugfix version, reset the unit, then apply your settings. Reporte back.
I have upgraded the firmware from 3.33 to 3.36.
Upgraded firmware to latest bugfix 6.37.4 (Bugfix only)
Reseted the configuration and configured wifi AC only 20/40Mhz indoors.
Unfortunatelly same results.
This is known problem by us too, and there is atleast 2 problems with WLAN in this product:
This is not solved till today.
I’m having hap ac lite and 70mbps with 5ghz in single chain with iPhone 5s and laptop with Broadcom wlan adapter. I think this is normal behavior.

Yes that is okay, same upload as download.
Thanks for input guys.
I have other hap ac lite that is working as expected, 96/96 Mbit.
We are trying to isolate this low download speeds with mikrotik support. They are showing great effort in debuging. So far it looks like it is not configuration issue, but lets wait for their verdict.
Helo, guys.
Any updates on this?
I am facing with the same issue. Tested on 2 MikroTik hap lite routers with diffrenet firmware. Issue is reproducible for both of them.
My ISP bandwith is 100 MB but MikroTik router gives me only 15-35 mb, sometimes 40-60 mb download and 70-80 for upload.
If ti check ISP connection direclt using LAN then i can see 98.5-99 Mb for download and upload respectively. Please advise how to fix it?
I am updating this post too.
Is this still a problem. I want to use these devices for local 2.4Ghz AP and then use the 5Ghz single channel as a uplink or point-to-point
link to another Hap AC lite device which would then transport the data out onto a LAN network and through another mikrotik device
that is connected to the internet.
For me the speed issue is not to bad as the networking devices will not have that good signal strength, mostly smartphones and
such so they might not even notice the slower speed on the local 2.4Ghz AP but still nice to know that the speed is there if you
need it.
Or is this issue gone, due to firmware updates and so on ? sounds like it was a firmware issue from the start ?
Anyone ?
The “Lite” series seems to be more focused on budget vs performance. I will say the hAP AC and the wAP AC works great. The lite versions I have tested have all sucked in the throughput area.
Perhaps if we were in a Faraday cage with only our Lite and the wireless device it might perform well. That being said the hAP AC, wAP AC & the RB951Ui-2HnD all perform wonderfully from a wireless performance perspective. Now if they would just add hardware acceleration to them we would be set.
Oh. So it would be better to go for the wAP ac device instead. That could work too, even though I would have to
get some MMCX-RPSMA pigtail cables and modify the device with external antennas.
Hmm, perhaps the cable option is better. It all comes down to cost and effort I have to put in, to get the network
up and running.
Thanks for the advice, I will stay away from that lite device.
