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

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

Don't know if you could make lwfinger driver work, but I found this one that works fine with 6.0.9 mainline kernel: https://github.com/HRex39/rtl8852be
