Can you disable the auto-rfkill behavior in the BIOS/UEFI?
Does it help to add "iwlwifi.remove_when_gone=true" to the https://wiki.archlinux.org/title/Kernel_parameters ?
Do you get better results when using iwd as NM backend?

Neither of these did anything.

Disabling this seems to have resolved the issue on kernel 6.6.5. Ideally I would like to be able to re-enable the auto-rfkill behaviour but I can live with this. Any idea why this happened all of a sudden in the first place?

The previous kernel had iwlwifi crash harder/differently

It seems that NM is less capable to deal w/ the new iwlwifi/iwlmvm response to the hard rfkill
Since the previous journal didn't show the iwlwifi chip in use at all, did this somehow work as supposed to (ie. you were using the ethernet and when unplugging that, just switched over to the WiFi)?

Grafcube · 2023-12-10 15:37:20

WiFi stays connected even when ethernet is plugged in but the top bar shows the ethernet icon. When I unplug it, it immediately switches to WiFi. The only annoyance is that both are active at the same time but it's not really a big deal.

Is this the status quo (after disabling the auto-rfkill) or the status quo ante?
I was wondering whether the wifi has actually worked before.

As for the status-quo, you could use https://wiki.archlinux.org/title/Networ … plugged_in and also soft rfkill the NIC.

I don't understand what you mean by that. The WiFi did work before in specific situations for NM. With netctl it definitely worked.

This works for me. The issue is now resolved. Thanks for the help!

What specific situations? Eg. booting w/o the ethernet attached?
I'm asking because we've not seen a journal with functional wifi on either kernel, the previous kernel just crashed iwlwifi "worse" so I wonder whether the wifi situation has been a regression or the auto-rfkill has actually never worked properly.

This works for me. The issue is now resolved.

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

It worked with NM when I booted without ethernet and it worked regardless with netctl.
