I used sunwire/dkms-8821au before kernel 6.13
sunwire/dkms-8821au Copr
and WiFi works fine, without failures.
Now my driver id rtw_8821au from
$ uname -r
6.13.6-200.fc41.x86_64
and my wifi dies periodically
time to death varies from 30 minutes to 10 hours
after the wifi died
my wlp0s20u2 state = DOWN

solution =
unplug the USB adapter and plug it back in
