All packages are up-to-date.

ifconfig is not showing my wifi-adapter but it shows ethernet.

Thanks for helping!

Re: Lenovo Yoga X1 4th Gen iwlwifi not working anymore

What is the output of pacman -Q linux-firmware linux   ?
Do you dual boot windows?

Re: Lenovo Yoga X1 4th Gen iwlwifi not working anymore

Yeah, but...  That is 7 months old, has been marked fixed, and is not the version that is installed.  All of which means naught.

kukasr, take a look at your pacman log.  Did linux-firmware get updated around the time this started?  You might try backing down to the previous version to see if that helps.

Re: Lenovo Yoga X1 4th Gen iwlwifi not working anymore

I upgraded on 25.12 therefore I don't think that the new version is the problem. I tried to downgrade to linux-firmware-20191215.eefb5f7-1-any just to check that but it didn't fix the problem.

I am not that sure but for me it seemed that this problem occured the first time when the machine was already running and I was working. Still after (many) reboots not working.

Re: Lenovo Yoga X1 4th Gen iwlwifi not working anymore

Booted a linux USB stick - wifi not shown (to old firmware) - reboot - wifi was working. Idk what the bug caused but my wifi is working again! :-)
