Wifi on mikrotik controller not working, why?

Question

Mikrotik

There are 3 microtics hAP ac lite, on one capsman is configured and the other two are added as access points, so the other two are visible as points and broadcast normally, and the controller itself does not shine wifi, why I don’t understand. The latest firmware is on all three.

Answer 1

found a solution
/interface wireless cap set caps-man-addresses=127.0.0.1

Answer 2

1) wlan is off by default.
2) It is necessary to transfer control of the wireless interface to the controller. So that wi-fi on the main microtic is also controlled by CAPsMAN

Answer 3

The capsman client process connects to the capsman server over the network, including within the same router. If there is a firewall on the capsman server, then the connection goes through it. At the same time, the firewall configured by default has a final blocking rule for all input packets except for the local network bridge. But if other routers are connected by wire to the ports included in this bridge and the firewall lets them through, then for its own process it looks different, the connection does not come from the bridge and is dropped by the firewall. The solution is to drop on the firewall only from external WAN ports.
It doesn't work like this:
add action=drop chain=input in-interface=!bridge
Does it work like this, add all external interfaces of providers and VPN to the WAN list? if needed:
add action=drop chain=input in-interface-list=WAN
