No ethernet on GA-Z77-DS3H High Sierra

I've got wifi working using a TP-LINK TL-WDN4800, but no ethernet option shows up in System Preferences. So far I have tried installing AtherosE2200Ethernet v2.2.2 using MultiBeast as well as ALXEthernet.kext to L/E using kextbeast. I've looked for days through the forums to no avail, so any advice would be much appreciated!

I've attached problem reporting files.
