Hi all. I recently RMA'd a motherboard from asus (asus sabertooth z87) and have received a new one. I have installed it and I am up and running. Windows 8 has booted fine and everything except it seems there is no detection of my Ethernet connection. I was wondering if this could have something to do with drivers since I technically got a new motherboard even though its still a sabertooth z87. Do I need to reinstall OS? Can I just try to update LAN drivers? Any help is appreciated! thanks!
