Ah, the driver is available at drivers/net/wireless/realtek/rtw88/rtw8822c.c

I would suggest you try a more recent kernel, such as 5.15.y then.

If you still observe issues, then please report them to the maintainer
and lists given by:
./scripts/get_maintainer.pl -f drivers/net/wireless/realtek/rtw88/rtw8822c.c

Hope this helps.
