I have been having this problem for a few weeks now. I am connected to Xbox live, have a gold membership, and I have a wired connection. However, every time that i try to play a game online it says that I am unable to connect to xbox live. When i play assassin's creed 3 it says i cant connect to Ubisoft. When i play Halo 4 i says i am not connected to xbox live,but as it says this xbox llive tells me one of my friends just started play halo 4. Also call of duty black ops 2 does the same thing as halo. I have checked every support forum that has problems like mine for all three games but nothing has happened. Please Help Me.
