It's there and the kernel driver is loaded.
Does "iw list" give anything?

I've included both dumps from the sick installation and from the same
machine, booted with the Live USB.
This is not accessible.
Looking through /var/log/messages for 02:00.0, I do see:
I assume that's a typo.
kernel: mt7921e 0000:01:00.0: driver own failed
There are a lot of hits for this, but it's not clear if this is actually
a problem or just something that gets logged.
I also see:
ModemManager[1976]: <msg> [base-manager] couldn't check support for
device '/sys/devices/pci0000:00/0000:00:02.2/0000:01:00.0': not
supported by any plugin
I don't think modem manager should have anything to do with the wifi
adapter. I don't know why it's even checking.
Try adding "pcie_aspm.policy=powersave" to the command line in grub and
see if that makes any difference. If not, then also try "performance"
instead of "powersave".
