Wifi randomly stop working

Hi there,

So the problem is wifi randomly stop working saying "limited connectivity" and after NetworkManager daemon restart system completely freeze.
Before updates that's happened more rarely but now it's almost every day which is very annoying.

linux 6.3.5-arch1-1
broadcom-wl 6.30.223.271-474

I've also tried dkms version but results the same.

lspci -vnn -d 14e4:

        Kernel modules: bcma, wl

journalctl --grep=wl

Would be happy to see any advice and help. Thanks

Re: Wifi randomly stop working

Looks okayish, might be a kernel bug and wl did at least have a regression in one of the 6.2.x kernels but that should be fixed afaik. Can you test/reproduce on linux-lts? Don't forget to install linux-lts-headers and broadcom-wl-dkms to test that.

So, I've tested lts kernel and results the same unfortunately.

Re: Wifi randomly stop working

Please post a complete system journal covering an affected boot:

sudo journalctl -b | curl -F 'f:1=<-' ix.io

for the current one.

Re: Wifi randomly stop working

Stop networkmananger, connect w/ wifi-menu from the netctl package.
If that works, disable https://wiki.archlinux.org/title/Networ … domization and try NM again.

Seems like netctl work without any issues, so then i've tried to disable NM mac randomization but it doesn't help.

You're getting disconnected and rejected from c8:bf:4c:4e:55:5d (the 5GHz AP), so try c8:bf:4c:4e:55:5c (the 2.4GHz AP)
