I have a RB2011UiAS-2HnD mikrotik with RouterOS 6.23. My internet connection is 100MBit and when using LAN I'm getting the correct speed, but when connected via wireless, the speed is not higher than 35MBit.
Connected a Dlink wireless router and with this router got 60Mbit, but with Mikrotik wireless got max 35mbit.
Tried to connect with many devices which are supporting the wireless N standard, but the speed was the same, not higher than 35Mbit.
Checked the forum about the similar issues with wireless, and tried everything what was there, but still no better speed over wifi.
In Registration table there are TX/RX rates like; 115Mbps/117Mbps, 58.5Mbps/58.5Mbps,and lower values
Can you check if you have enabled both chains for send and receive on the wireless properties?
Can you check if you client actually connects with 40Mhz and not just 20Mhz? You can see this at registration and then the channel and type it select
In the same window you should be able to see Signal to Noise ratio, this value is interesting too
Did you do a channel survey to see which channel could best be used?
With an RB2011 I have been able to achieve around 110Mbit/s to 120Mbit/s of actual throughput. This is the absolute max though. But something like 80Mbit/sec or more should be easily achievable, even with some walls, etc.

1 - Both chain is enabled
2 - I think the client connects with 20Mhz, not with 40 Mhz - I’m not sure with this
3 - Signal to Noise: values from 15 to 40dB
4 - using the channel not used by other networks
Checked the wireless connection inside the same room where is the RB2011 and in different location(1 wall), got the same result.
Hmm, that signal to noise ratio is pretty low. In the same room you should at least be able to achieve something like 60dB. It could be the cause that your client is not connecting any stronger.
Do all your devices share the same low speed and Signal to noise? Things like your smartphone, etc.?
About the 20Mhz and 40Mhz. When you check in the routerboard under wireless → registration → click on client. In that window you can see bars and “last used” and it says either 20Mhz or 40Mhz, etc.. But there seems to be another reason why your client isn’t connecting very fast. Better speeds require a better signal to noise ratio.
In room or with 1 wall in between should not make too big of a difference with 2.4Ghz.
Please check with different clients and see if you still get such low Signal to noise values.
Hmm, odd, if all your devices seem to get a bad signal to noise ratio it would suggest maybe you RB2011 is faulty in some way. Maybe you could try opening it up and unplugging and then re-plugging in the antenna’s to see if that might make a difference.
Setting to only-N should make no difference in this situation. You could try a reset as suggested, but that won’t do much for your Signal to noise either I’m afraid.
