Just switched some hardware parts in my main PC:
- MB: TUF GAMING B550M-PLUS
- CPU: AMD Ryzen 5 3600
- Ram: G.Skill RipJaws V schwarz DIMM Kit 32GB, DDR4-3600
I moved from Intel to an AMD build. I kept my boot disk with Linux Mint 20 and everything was running out of the box, except there was no ethernet connection available. The RTL8125B Realtek network card is not yet supported on a Kernel < 5.9. Since I’m running Kernel 5.6.14, I had to manual install it.
Download the “2.5G Ethernet LINUX driver r8125 for kernel up to 5.6”, untar and follow the installation instructions from the README. In fact you only have to run
sudo ./autorun.sh #check with lsmod | grep r8125 ifconfig -a
