or 3. linux65 doesn’t exist anymore in the repo and therefore no wl module for this kernel. linux65 needs to be removed on your system.
That is strange… i can only find these:
$ LANG=C pamac search -f brcmfmac43602-pcie
/usr/lib/firmware/brcm/brcmfmac43602-pcie.ap.bin is owned by linux-firmware
/usr/lib/firmware/brcm/brcmfmac43602-pcie.bin is owned by linux-firmware
Could try this command on the live session?
find /usr/lib/firmware/brcm/ -name "*brcmfmac43602-pcie*" -exec sha1sum {} \;
Then compare the checksums with the same command on the local installation.
