I own GA-Z77X-UD3H and I've recently noticed that my system has stopped detecting on board ethernet. It's not showing up in Device Manager and when i try to install drivers i get error message "Installer can't find Qualcomm Atheros AR81Family ethernet controller on your system".
When i plug ethernet cable LEDs on router and next to LAN port are not lighting up
I've tried updating BIOS, reinstalling system and using untouched second bios from DualBios feature. I thought that it just died and considered RMA but AIDA64 ( former Everest) is detecting it.
Windows 8.1 Pro x64
QuadCore Intel Core i5-3550

Ethernet controller is enabled in bios
