i can not figure out why i can not connect to xbox live. it started last night, i thought maybe a tower was down or something. then today it still isnt working. ive tried all the troubleshooting steps that xbox.com told me to try ad none of them worked. i have a netgear wireless router and it is turned on and the wireless is working clearly because i am on my computer typing this up. it randomly said i was not connected. when i go to connect though, it says that i have a 4 bar connection to netgear. what is wrong. somebody help me.
