Hello everybody, maybe 2 weeks ago i installed windows 7 ultimate on an Acer 7735ZG laptop (activated with a patched bios), i installed all windows updates available and all was ok during many days, internet connexion was stable and running pretty fast now i'm facing a problem since some days, the connexion through wifi became very unstable, it randomly disconnect or lose speed im quite sure it is from one of the windows updates because i didnt install anything else since i got that problem.. i read on microsoft forum that some other got the same issue after installing latest updates from 10/02/11 but even after uninstalling them, it's still the same i also updated the wifi with lastest drivers (wifi card is PCI\VEN_168C&DEV_002A, Atheros AR5008) but the same if someone can help or give advices it would be nice Thanks!
