This is really frustrating. Every so often (say about half hour) the internet would suddenly just not work. the wireless card is still connected to the router but internet wouldnt work. If i repaired connection (like reconnect) then it would work fine for another half hour the wireless router is a bit far away but i always have Very Good Signal and its nothing to do with that. Iv tried 108m mode and 54m mode with dynamic and static Ips. using WEP encription BTW Happens on all Operating systems and its not a Driver Problem i dont think Router : TP-Link TLWR642G Wireless PCI Card : Atheros AR5001X+ they are both same chipset.they should work <_< never used to do this any ideas?
