I keep getting disconnected from Xbox live during game play, the intervals are random I can play for 20 minutes one time and 5 the next, game makes no difference Call of Duty or battlefield3, as well if I'm watching a DVD through my 360 I'll see a message appear saying I've just been disconnected from live.
My NAT is set to open
Hard wired to a Belkin f5d8233-4v3 router
I looked up port forwarding I currently have nothing in my virtual servers and when I try to add ports 53,80,88,1863 and 3074 (as per Port Forwarding's website) I keep getting a message that says "line 1 is incorrect".
Any help appreciated.
