WIFI broke after update, how to rollback on Kinoite?

Ask Fedora
1

Hello!
Unfortunately a Kinoite update left me unable to connect to any WIFI. I already tried rolling back via rpm-ostree rollback but that didn’t solve anything. Unfortunately that the is the only point I can rollback.
What else can I do? Investigating the journalctl outputs suggested that a kernel update could be the problem.
What would you suggest doing?

WiFi issues with linux update are not unusual, so I keep a USB WiFi dongle to use while troubleshooting. When reporting problems, you should provide enough detail to allow others with access to similar hardware to reproduce (or avoid!) the issue. You should try to do this before rolling back the update. If you don’t have internet you can save text files where they will be accessible after a rollback.

Please provide the output from running inxi -Fzxx in a terminal (post as pre-formatted text using the </> button froom the top line of the text entry panel).

You may be able to find more details of the failure using journalctl “filters”. It can take some effort to find “filters” that select relevant details. You may need to study man journalctl, but for starters, try journalctl --no-hostname -b -g wifi | cat(we don’t need to see your hostname, and the |cat wraps long lines so they don’t get cut off when posting (as pre-formatted text). The -b and -g options are explained in man journalctl.

Thanks for the help. I ran rpm-ostree rollback again and rebooted which resulted in resolving my issue.
Additionally I executed inxi -Fzxx which isn’t installed on my system - so that would be a dead end too on a machine without a working connection. Right now I am facing a WIFI issue with eduroam which I am unable to connect to - the journalctl output while a connection attempt is made:

The inxi output shows us the hardware devices so should not change too much with a rollback, so please provide it.

Were you able to connect to eduroam before the update? Did you use the eduroam Configuration Assistant Tool from your institution? Sometimes updates can result in changes to configuration settings stored in individual user’s directories. Such changes will not be reversed with a rollback. I think most institutions have manual configuration pages like Connecting to eduroam WiFi Linux.

See: Wikipedia article on IEEE 802.1X for an overview of the authentication process which may help you recognize how or why the failure occurs.

Yes, I was able to connect to eduroam beforehand and successfully used it since the start of this year so it did survive several updates.
Thank you in helping me out.

Now that your hardware details can be found by web searches, we can hope for help from someone with similar hardware. Several things you can do:

  1. check dnf info mt7xxx-firmware.noarch package. I have:

Description  : Firmware for Mediatek 7600/7900 series WiFi/Bluetooth adapters

The problem update may have installed this version. Firmware in laptops can be tricky – there can be extra system-dependent steps needed to ensure that the WiFi chip reloads the firmware (WiFi may active even when no OS is running to support Wireless Wake on LAN).

  1. Check for issues with configuration data stored under your home directory by creating a new user. I assume you will have to configure eduroam for the new user.

I was able to fix it myself. It should have been very obvious while reading the output of the wifi connection process (via journalctl) and tried my luck by excluding the CA certificate from the saved connection - that made it work again. The months before it was needed and all of a sudden this added to my initial confusion. What a stupid coincidence…
