Hi guys, I'm hoping somebody can give me a clue as to what's going on ? Just lately when I connect to a Wi-Fi network after about 20-30 mins I'm kicked off. I then have to either choose the repair option of " get a new IP address automatically, Though if its automatic why do I have to tell it to do this???????, or refresh the network adapter. Sometimes I have to re start to clear the problem. I'm running windows Vista ultimate. I have tried to update the network adapter driver but it tells me the best driver is already installed. Windows is fully up to date. Any ideas ??????????????????? Its now staring to do my head in and I'm close to some serious computer rage!!!!! HELP !!!!!!!!!!

Does it happen only on one router at home or others as well? If only one, what's the router? Who's the provider?
