Hi, i have windows 7 x86 build 7022, with an onboard ethernet adapter "atheros L1" with vista drivers, RUN OK. I installed Win7 x64 uild 7057 with the same drivers, but the problem is that after a few minutes the network adapter looks "unplugged" if i restart win7 the problem disappear... but did not have that problem before with win7 X86 build 7022.
And is very tiring, restart the computer each time this happens.

Sorry for my bad english.
