One of 2 wifi disable

Hi.
I have hAP Mikrotik router. I have simple config - 4 ports connected to masterport, one wan, both wifi int connected using bridge to masterport. It is working, but sometimes one wifi interface disable (status showing R instead of RS). I don’t know what is the pattern.

Any ideas?

R is running. S is slave. When it is running it is not disabled. Are you sure you described the problem correctly?

See the log anyway.

Yes, you are right. Sorry for that - there are S instead of RS. If i disable wlan1 wlan2 start working. sometimes both working fine.

It will not show R, if there is nobody connected. It is not an indication of problems. It is normal.

Ok, i understand but why i can’t see this network at list of network? I can’t connect it.

Again. See the log. If no details there, enable wireless debug logging.
