Hello!

Could you please help me debug this issue that is preventing me from having wifi connection.
iwlwifi throws the following error during boot (dmesg) that could be the reason the wlan interface remains undetected.

This device was not initialized properly in the independent probes of the same device from other Linux users in the database as well. It's highly likely that Alder Lake WiFi is too new for Linux 5.16.x.

Try Linux 5.17 first.

I've added 5.17 to the database, but lkddb parser failed to find support for this device in it. So, probably upgrade to 5.17 will not help and you'll need to wait for 5.18 at least.

Thank you for your quick reply!
I will give a go to your suggestion and come back with an update.

Cheers,
FM

Great news, it works with 5.17 (currently `linux-mainline` arch package)! And it looks like the `linux` arch package will be updated soon - link.

Thanks,
