I have a Dell XPS 13 2016 (9350) that is running Manjaro since I first handed it back in earlier 2016. After the last system update, the Wifi is not working anymore.
Gnome lists the wireless option in the top right menu. But it doesn’t list any network available although there are plenty here.
I read all the troubleshooting guides again but I was unable to fix it. The clue that I have is
$ sudo dmesg | grep brcmfmac

The most relevant information is brcmf_c_process_clm_blob: no clm_blob available (err=-2)
. What am I missing here? How can I solve my wireless network?
