Home Wireless Connection Problem

[Sean D]

I currently have a wireless network connection set up on my 2 pcs. I have Comcast cable running to my main computer in the living room, with a Linksys wireless router connecting to my second PC in my room.

Problem is, on my secondary PC, after a couple hours of being idle, I am unable to browse the internet and am forced to restart. Other applications such as downloading files, and usually even playing poker, still work. But Internet Explorer can't connect and I am not sure why. When I restart the computer, all is fine again, and I am able to browse the internet again. So its really a pain to have to restart every time I come home. Any help is appreciated.

Thanks
