RTL8822x Firmware for GNU/Linux
The files in this repository are taken from Linux Mint 19.3 and will allow a Realtek RTL8822 b or c card to work on other distributions.
The files have been tested with Debian Live Testing ISO with non-free firmware included (https://cdimage.debian.org/images/u...firmware/weekly-live-builds/amd64/iso-hybrid/).
If you have trust issues, you can always boot with Mint 19.3 and take the files from there to use.
Log in with your favorite distribution, preferably with a new Kernel, as this has only been tested with 5.4+ Unload non-working modules from the Kernel, with:
modprobe -r rtwpci
modprobe -r rtw88
You can run lsmod to see if they are named somehow differently in your OS, in case you do not run Debian.
Copy the files from this repo to your system, change the kernel path as needed! Load the modules with modprobe rtw88 and the WiFi should work.
It is unclear to me whether the /usr files are needed or if everything will work with just the files under /lib. Feel free to open an issue about this.
