Re: mediatek mt7921u wifi issue with recent firmware-misc-nonfree upgrade

Thanks Jan, for pointing me in the right direction.

After installing firmware-mediatek, my issue is solved now.

I have missed the earlier log entry, where the firmware file could not
be loaded.

I just didn't notice that there is a separate package for mediatek
firmware files now. Because they used to be part of
firmware-misc-nonfree until version 20230625-2.

But they're no longer present in firmware-misc-nonfree 20240709-2~bpo12+1.

Maybe I just got hit by this, because I've disabled recommends in my apt
config. And firmware-mediatek is in the recommends of
firmware-misc-nonfree :-)

Thanks again everyone for your replies.

Have a nice Sunday.

Regards,

Jochen
