I'm not good at linux and I have number of issues with WiFi and Bluetooth with my new Legion 5 15ACH6H.
Previously I used https://github.com/lwfinger/rtw89 repo for WiFi driver installation with bellow commands:
Code: Select all
#/bin/bash
git clone https://github.com/lwfinger/rtw89.git -b v5
cd rtw89
make
sudo make install
sudo modprobe rtw89pci
My bluetooth didnt work at all. It cant discover devices around.
While I read this topic I run number of commands install some packages e.t.c. after that my bluetooth start to discover devices and even connect to them.
Unfortunately connected device become disconnected randomly. Like in loop. Connecting - Disconnecting. All I can debug with dmesg is bellow:
