ok, I think by forum standards here this board may be a bit old but I'm having an issue running Windows 7 x64 and the drivers for the Atheros L1 Gigabit Ethernet card. I've found a few post talking about an updated driver but can't seem to find one that ultimately fixes the issue.
What happens is the system runs fine for long periods of time and then all of a sudden the network decideds to become "unknown" and you lose your internet connection. The simple work around is to disable then reenable the NIC but that only works until it decides to do it again (2 hours or 30 hours). I'm not sure what triggers it and I've pulled down the latest driver from Windows update (18.104.22.168 dated 6/22/2009 from Atheros). Any help here would be great.
