Can not connect with people on Xbox 360

Question

Ok here is the initial problem. If I try to join with someone on my xbox I'm unable to. I have checked the xbox.com site and opened the ports that they suggested. This opened up my NAT. I'm using a WRT54G Wireless-G Broadband Router, and have upgraded my firmware just yesterday (11/14/08), then unplugged my router, modem, and shutdown my xbox 360. I waited 30 seconds and starting with the router started plugging them back in, waiting, and continuing on to my modem, then xbox. I've done just about everything I could think of, and have been told. After all this no sucess. If anyone has an idea I would be greatful.

Let the power blink for 1 minute.
After this reboot the router and try logging using admin as password The resetting of router is indicated by flashing of power light   To get WEP key, connect your computer to one of the four ports on router using ethernet cable.Open setup page of router by typing http://192.168.1.1 in browser;s address bar, and typing password as "admin" and no user name.
