Cannot connect to wireless network/interface after kernel update

Hello!

Earlier today I ran pacman -Syu, rebooted and my wifi no longer worked.  I noticed that wpa_supplicant and the linux kernel (among others but those 2 struck me) were updated.

Downgrading wpa_supplicant did nothing, however downgrading the kernel (from 6.13.1 to 6.12.10) did resolve the issue.

While running 6.12.10 networkctl outputs 3 interfaces, the 3rd being my wlan connection. The wlan is lost when I run 6.13.1. if I do lspci -v I get that my Broadcom  PCIe wifi card has 2 kernel modules, bcma and wl (in use), however when running 6.13.1 it only gives 1 module (bcma), and none in use.

I'm gonna be honest I can't remember how I setup my wifi when I did it, as that was probably 7 or 8 years ago, and this is the first issue ive had after an update (touch wood). How do I get the new kernel to use the wl driver/module?

thanks

Re: Cannot connect to wireless network/interface after kernel update

See https://bbs.archlinux.org/viewtopic.php … 4#p2224434 likely fixed in the next broadcom-wl-dkms update (FWIW since broadcom-wl was removed, if you were using that, switch to broadcom-wl-dkms and install linux-headers)
