Late last month I removed my 2.4G SSID from wpa_supplicant.conf which
finally got my Intel Alder Lake card to associate with my 5G SSID and set
the mode to 11ac. This worked fine until I re-booted. Now the network
failed to start, spitting out repeated 'No beacon heard' messages with the
interface rapidly moving DOWN and then UP, finally giving up and leaving
the Interface DOWN.
After logging in, I did 'service netif start wlan0' and the network came up
fine and continued to be stable until I next rebooted the system when the
same thing happened again.
The log of the event is attached. Much is repetitive, but kept changing a
bit until the network was restarted.
I am seeing this at times in my development bhyve but I wasn't able to
pinpoint it to anything specific yet.
service wpa_supplicant restart wlan0
should be enough to get you out of this; usually no need to throw away
the entire wireless interface and re-create it. I would say in 19 of 20
times this happens that's doing the job for me; there are times when I
have to do it twice.
Out of curiosity, was it warm restarts or cold boots from power off?
