I have a plenty successfully installation of BigSur, all it is working except Ethernet, I installed several versions of RealtekRTL8111.kext on EFI->OC->Kexts but still doesn't work. I am using internet with Wi-Fi, but I want to use wired.


The mother board it is a Gigabyte Z490 UD

Can anyone help me?


How do you know there is Realtek LAN chip? I think there must be Intel LAN.
