I've read and tried the steps suggested in stickied threads but I can't connect still, so here is the information for my system and such:
What Country/State/Province do you live in?: US, New York
Modem brand & model number: Unknown
Router brand & model number: Unknown
If Wireless, are you using a white or black external adapter, or an internal (Xbox 360S) adapter?: Internal Adapter
After you run "Test Xbox LIVE connection" press “Y” for "More Info”. In the pop-up that appears, what are the following values, if shown? (If a value below does not appear for you, just leave it blank.)
W: 0000 - 0021
X: 0000 - F001
Y: 00A8 - 4820
Z: 0000 - 0000
ID: FFFF - FFFF
L: 8015 - 1000
Q: 8015 - 1004
D: 18.104.22.168, 22.214.171.124
Also more info: I can connect to the internet just not Xbox Live.
When I am trying to connect it is while playing Assassin's Creed: Revelations to try and get the exclusive content I got when I got the game. A window pops up occasionally in game for a split second, it looks like it is trying to update but it never does.
