Atheros L1 Gigabit Ethernet on windows 8 disconnects

I have a P5KC Asus motherboard which comes with a Gigabit adapter onboard. The problem is that Asus has stopped support of the MoBo since Vista and my machine is perfectly fit to run win 8 (actually I just got 8.1 and I remembered to do this post). Windows 8 detects vendor id 1969 and device id 1048 as Atheros L1 Gigabit Ethernet 10/100/1000Base-T Controller, but I had the problem of the network being disconnected after a few file transfers or video streams.

Modifying devices and drivers on windows
