Distorsion

I tried to install Realtek 2.2.2 version on multibeast but im only getting a Cable Disconnected from the network settings pls I need help. I also tried with the other 2 Realtek versions and nothing.

What driver do I have to download and just put it in the EFI folder?

I installed High Sierra and everything went smoothly during the installation process but after i booted up macos didn't detect any ethernet ports. Motherboard: Asus H110-D CPU: I3 7100 it says built in serial port If you have any ideas i would be grateful.
