According to the command output above, my device has Realtek 10ec:b852 wifi + bluetooth combo card. WirelessCat says that this card should work with rtw89 driver
Neofetch
Why is the kernel 6.0
On this particular lenovo keyboard didnt work unless i used the latest available daily kernel from ubuntu, mainline unfortunately didnt provide it either.
What drivers I've tried
Both were installed exactly as per the github instructions. I did not try them both at the same time. When i switched between them i uninstalled one and then rebooted before installing the other one.
I installed drivers without secure boot which is currently completely disabled along with all other bios security features(i triple checked) Installations on both drivers were successful to the best of my knowledge and running
sudo modprobe -vr 8852be
sudo modprobe -v 8852be
returned no errors either.
modinfo 8852be
shows the available options for the driver
