No Ethernet for new build

Hey there, followed the dortania guide to build a usb installer for macOS. Build seemed to go well, expect I can't get ethernet working to get past the installer. I've tried the Realtek RTL811 kext with no success. I installed the kext by putting it in the kext folder and then using the snapshot feature on propertree. Any advice?

Hardware:

i7 8700k

Aorus z370 mobo

msi rx 480 4gb

nvidia gtx 1080ti for windows

32gb ram

Killer E2500 ethernet
