When I try testing my xbox live connection, it starts the last step but fails alittle halfway into it. It says that my xbox is connected to the internet but isn't connected to xbox live and that my firewall might be blocking it. I've tried changing my ports in my interent configuration to the prefered setup and turning my router and modem off and back on but it doesn't help. I'm using a wired connection and have a Wireless-G Broadband Router, Model WRT54GS. Please Help.
