After setting up port forwarding, DHCP lease on IP won't renew

[Starfire]

I set up port forwarding a few days ago. Tonight, after BitComet was downloading for a while, I could not connect to most sites on the internet. Then I could not connect to anything, but BitComet was still downloading. Once I shutdown BitComet, my internet browsing would return most of the way and once I rebooted, it would come back completely. Then I went in my router admin program to see if there were any problems and it lists my DHCP lease for this computer as expired. What is causing all this and why is it happening now? It's worked perfectly up until now.

It's not that BitComet is using ALL the bandwidth because I have bandwidth caps activated in BitComet. I haven't changed anything on my computer between then and now. Here are the specs:

Windows XP SP2 Home Edition

BitComet 0.70

Router: Motorola WR850G

Wireless Connection to router via a Motorola WU830G Wireless USB Adapter

If you have set up port-forwarding properly, then your router's DHCP lease from your ISP would not be affected. This suggests that you haven't done it properly, and have changed something that you should not have changed.

Most likely, you assigned your router a static IP address. You can't do that. The router's connection to the ISP is dictated by the ISP and you can't change it without losing your connection. It's their way or the highway. So put that back the way it was.

It is your computer, not your router, that needs the static IP.

I never even touched that part of my router admin program. I know I can't set that IP address as static since it is the ISP that assigns it. The one I setup was the one that the router assigns my computer on the network. Besides, if I did screw that up, none of the computers should be able to get on the net at all and all of them can. I'm on one of them right now. The only thing I did to the router admin program was to add the port for port forwarding to the "routing" tab. I couldn't figure out how to assign a static IP to this computer, so I never touched any of the other settings.
