Windows 7 Home Premium
One computer on network loses internet

Computer Model: Dell Inspiron E1505
OS: Windows 7 Home Premium 32-Bit
Wireless Card: Dell Wireless 1390 WLAN Mini-Card
Router: Linksys WRT54G v8.2

This is an extremely frustrating problem I've been dealing with. It was happening for over a week, and then it stopped... now it's back again.

There is one computer on my network which randomly stops connecting to the internet. It runs Windows 7, while the other computers on the network run either Windows 7 or Windows Vista. It's still connected to the network, with full bars, but it will not actually connect to the internet. Browsers do not show that there is no connection, but instead try to load the pages forever. Sometimes I can restart the computer or disconnect and reconnect to make the internet work again, but it still only works briefly before stopping again.

I do have a network bridge set up between my wireless card and LAN connections, in order to provide online for my Xbox 360, but even when I try to remove the wireless from the bridge, it still refuses to work. I've also tried changing the router's channel, but that hasn't helped either. There's also no malware causing this, as I've scanned with several programs, and cleaned the registry as well. And of course, I've searched all over the internet for an answer, and found nothing... does anybody have any insight to this, at all?
