Reporting the same thing. At my end it looks like an issue with the AP itself,
not iwm but maybe more expert eyes see something I don't? I've seen this once
downstairs where the family has an imac on wifi, and it also disconnected at
the same time, and reconnected. I collected all this for the Ubiquiti forums
but maybe it helps here.

I'm using intel 8265, WPA-PSK, and unifi UAC Pro AP. I've been seeing this
for ~ 5 days, around the time my UAC firmware got bumped to 3.9.27.8537, and
also the last CURRENT update I did.

Sometimes it's brutal (every 1-2 minutes) and other times it takes a while (hours) to occur:

this time I got both the wlandebug output and also /var/log/messages & pcap from
the AP. I'm not sure how much privileged info is in the AP pcap so its available
privately on request if needed.

laptop - looks like a normal exit of the AP to me:

I'll roll back my boot environment and let you know if it behaves differently.
