[Solved] Problems Realtek 8852

#1 Post by Matteo294 »

Hello,
I recently installed Debian 11 (kernel Linux 5.10.0-19-amd64) and I am experiencing some problems with the WiFi module.
After the installation, the WiFi option was not showing up, so I manually downloaded the drivers from https://github.com/lwfinger/rtw89 and installed them. The WiFi was then working but terribly slow compared to e.g. the phone.
I read somewhere that the problem might be due to conflicting drivers. I tried to blacklist the one that I do not need but not only I couldn't figure out which are the ones that I need, but it also seems that the blacklist command does not work: I tried to blacklist all the available drivers and the WiFi was still working after reboot.

I attach some screenshots to give more details:

Can someone please help me? I am not very expert with Linux systems

Try -
Install firmware-realtek from non-free repo.
Install the most recent kernel from bullseye-backports

Updating the kernel from backports seems having solved the issue. Thank you very much!
