My console will connect to Xbox live when I start it and log in, but when I start a game from the dashboard it disconnects from live and i cant reconnect. when i try to test my connection all it says is that I need to restart my router which is not my problem because i have tried that multiple times with no avail. This started when i tried to download the latest Call of Duty: Black Ops update and it wouldn't download. so i tried again later and it wouldn't even bring the update up I would just get disconnected form Xbox Live. Is there any way that I can fix this?
