After installing win 8 on a new computer with a z97 extreme 4 motherboard, I had no problems accessing the Internet, upon upgrading to win 8.1 I'm no longer able to. Going into
Device Manager, Network Adapters there are no shown LAN adapter options.

The bios and drivers have all been updated to the newest version. Regressing to win 8 solves the problem but is obviously not ideal. Help please!
