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.
