I just bought Mikrotik hAP AC^2 and I configured it's WiFi to be controlled by CAPsMAN. The problem I have is that when I connect to it with my laptop (MacBook Pro 2016 Touchbar) I cannot achieve more than 110Mbps. On cable I can achieve 560Mbps.
Provision:

In registration table I see 866Mbps and it's using both antennas, but when I test I get only 120Mbps. The device is 1M away from router, ALMOST clear. (there is a wired PC between them)
This is signal strength from device:
PHY Mode: 802.11ac
Channel: 36
Country Code: BG
Network Type: Infrastructure
Security: WPA2 Personal
Signal / Noise: -50 dBm / -93 dBm
Transmit Rate: 527
MCS Index: 6
After detaching 5GHz interface from CAPsMAN the speed raised to 400Mbps. After attaching again I saw I hit the CPU limit.
cpu-used: 26%
cpu-used-per-cpu: 0%,1%,4%,100%
This one is when I'm detached from CAPsMAN.
So I'm hitting CPU limit - but why?
