Well, I have Comcast cable internet and I have 2 computers connected to a Linksys router, WRT54G, one my work computer and the one that I need for my job and the other my gaming rig.

With everything plugged in, router and modem, I can access the internet fine on the gaming computer, but on the other computer it's very odd. When I try to use Firefox, my homepage doesn't even try to load. It just says "Done" at the bottom left of the page. If I do ipconfig/release and renew I can use Firefox and IE for about 10 seconds, then I have to do it again so I can use it again If I don't, I get that damn "Done" message. However, things like ventrilo work sort of even after the browsers don't work. Xfire takes long to start but eventually does, and I can't connect to Steam or play games online on this comp (even though I probably won't on this computer, just extra info).

This has never happened before, and I have also tried directly connecting my computer to the modem without a router, still no luck. The gaming computer can get online fine, both directly to the modem and through the router.

I can also ping websites, i get a 0% loss and I can even ping IP, but still no internet

I've called Comcast technical support and their phone technicians really don't tell me anything I know already. All they tell me to do is unplug my modem for 20 seconds and then plug it back in (like I haven't tried this already).

Please, if anyone can help with this it will be greatly appreciated. Ever since my Internet hasn't worked for me, I have been unable to get any work done.

If anyone needs more information, please ask and I'll provide.
