Hello !
I have CAPsMAN running on rb2011 and have hAP ac, hAP ac lite, cAP connected to it and it works.
Now, Im connecting wAP ac to it and when I try connecting clients to it, wAP ac disconnects wrom CAPsMAN with log entry "CAP disconnected from rb2011"

No other CAP gets disconnected in the same fashion as wAP ac does.

Can you help me please?

I did more testing, it still disconnects.
Can somebody guide me into troubleshooting please?
Mikrotik support is not responding ...

If you want help, you need at least post some more information like a network diagram, configurations and the like.

This is my setup:

adsl - rb2011-lan cable -switch - 4 lan cables, to hap_ac, hap_ac_lite, cap, wap_ac

CAPsMAN on rb2011 register all CAP.
Originally there were hap_ac, hap_ac_lite and cap and it ran good, clients roaming between mtiks.
I added wap_ac, reset it to defaults, setup as CAP, connect to CAPsMAN, all look good, just like rest of CAPs sitting in CAPsMAN.
When there would be more than 2-3 clients connected to either wap 2.4 or wap 5, the problem would arise, wap_ac would disconnect and reconnect to CAPsMAN right away.
Wap_ac temperature would be 60-70 C.
When i would test wap_ac as standalone access point, no problems, 10 clients and all good, no hiccups.

Heres configuration:
