I’ve just received hAP ac². Turned it on and use the ‘default’ settings (what came out of the box).
When I connect my two computers using wires I get 800 Mb/s (I’m OK with this).
When I connect one computer wirelessly (802.11ac on 5Ghz) the other is connected through cable, I get 50 Mb/s. The wireless distance is 1m. There is no other wireless router or phone or any device near.
Why is the wireless speed so slow? What to do to improve it?
Thanks for help.
It’s normal with hap ac2.

Does you computer connect on 2,4 GHz Interface or on 5 GHz?

How?
Make a screen shot
Just make some test with large file transfer. Laptop is Lenovo X220 with Intel Centrino Advanced N-6205 300Mbps adapter and another PC is connected with Ethernet cable. Channel width is 40MHz and adapter is rated 300Mpbs/300Mbps, no other station on 5GHz near me. The speed vary between 185Mbps and 200Mbps as seen from attached screenshot. RouterOS version and firmware is 6.42.10. I don’t have ac adapter to test with, but with n adapter I think results are O.K. Posting your config will be helpful to find out what is wrong.
This is near maximum for n Standart, please make picture from registration tab too
I have updated hAP ac² to 6.43.8.
Now I get about 400 Mb/s from my computer to the server and about 250 Mb/s from server to my computer (wirelessly). Of course speed fluctuates quite significally.
When I move my laptop to the next room (one wall) speed drops to about 100 Mb/s. 
The test parameters are below.
I don’t have screen shot from registration tab, but in time of the test laptop was rated as I said 300Mbps/300Mbps Tx/Rx and distance to the router was 1 meter.
