Just leaving a note to myself for future reference.
Needed to rebuild the kmod-wl package because of a borked update process (something made the computer crash mid-update).
A bit of Google searching brought me to the script in
sudo /usr/sbin/akmods --from-kernel-posttrans --kernels `uname -r` rebuilt the missing kmods and a
modprobe wl got the wifi back up and running.
