Hello Everyone:
I have an Acer Nitro with AX203 & Asus Vivobook also with the AX203. Both are
running FreeBSD14.3p2 along with Win11 (the Nitro also OpenBSD) with Intel
CPUs. The issue is that iwlwifi sometimes comes up and connects and other
times does not. It appears sensitive to the AP it's connecting to but I am
not certain. The only way I can clear this issue is by a power cycle. I
observe different behavior at home, office, or when on travel connecting to
random APs. There is no problem with wifi when running Win11 on this
hardware.
Here at home tonight I had a stable connection, rebooted (no changes), and
was met with error messages on the console and a continuous stream in
/var/log/messages. The laptop is next to the AP. If anyone has suggestions I
would really appreciate it. Thank you.
I saved a dmesg verbose, ifconfig -v wlan0 if that would be helpful.
Here is a snip of the dmesg error messages after reboot:

So this is one issue. You'll find reports about this for the last years
and all kinds of Linux as well.
Some people said rebooting from wondows to another OS makes all kinds of
weird things happen (if there is no power off).
Funny enough some people said rebooting the AP helped.
If this happened after a reboot I wonder if we left state on the AP and
the AP is dumb but more likely it's other filtering stuff in the FW
which should be cleared but wasn't.
I have some work in progress here I'll try to get into main to see if
that'll help a bit at least.
Does it make a difference from reboot to doing a power off for a few
seconds and turning the laptop back on.

That's station removal from firmware. I wonder if something else had
happened which we cannot see in the log snippet you posted.

At this point I'd do a:
ifconfig wlan0 down
service netif restart wlan0
and hope that'll work.
