I updated the distro and wifi stopped working.
Thought maybe it was due to the non free firmware not being installed, so after some googling i installed the “firmware-linux-nonfree” package and rebooted and it did nothing, after some more googling I used “dmesg” , reviewed the fairly long log, used the debian wiki page linked in the log and installed package “firmware-iwlwifi” and it worked.
Suggestion for improvement:
-
upgrading non free firmware should work (and yes i added “non-free-firmware” to the souces.list file before upgrading).
-
missing non free firmware should be reported in the GUI.
-
the package “firmware-iwlwifi” should be included in the package “firmware-linux-nonfree”
-
debbugs (debian bug tracking system), either needs a lot of work to be just deprecated, i should be able to submit a bug using a web interface like gitea/gitlab/forejo.
