I am on it cache looks like this:

$ apt-cache policy firmware-iwlwifi

Downloaded both firmware debs. I guess that helps already switching kernels.

I don't see 'bpo' in the kernel version. It looks like it's the excalibur kernel. Please post your /etc/apt/sources.list and any other sources apt is using.

I just booted excalibur with that kernel and firmware-iwlwifi is working correctly. (version 20250410-2)

I upgraded the kernel to 6.12.38+deb12-amd64, bootet into it and the wi-fi was offline. Then, I bootet the old kernel 6.1 again and wi-fi was online.

Since you are using a package that is one generation release on from the default you are using, I would check to make sure you have the iwlwifi packages from the same source as it installed too. The daedalus-backports should have the firmware-iwlwifi need to match that kernel looking at the Debian packages that should be there in it.

At least that is what it would give me if needed running the same kernel on excalibur.

zeus@9600k:~$ uname -r
6.12.38+deb13-amd64

Edit: and I would make certain you have backup network connection that works before installing the wifi package and risking having none if only method of connecting fails with that package too.

Hi all,

I upgraded the kernel to 6.12.38+deb12-amd64, bootet into it and the wi-fi was offline. Then, I bootet the old kernel 6.1 again and wi-fi was online. dmesg log shows that the firmware is not found. Any ideas how to solve this issue?
