Description:

When booting my friend's AX201 card disappeared. This happened after upgrading linux and linux-firmware, seemed to be fixed by downgrading linux-firmware but after closer inspection it wasn't either of these packages. Possibly a race condition.

Steps to reproduce:

Boot the computer and try to connect to Wi-Fi. Rebooting may fix this.
