For the last few weeks I've been having a recurrent problem... and it's more of an annoyance rather than a critical issue.
Every 10-15 minutes when in a "offline" state, as in playing a single player game that does not require use of the Xbox Live service, I'm disconnected for reasons I cannot explain. I've tried resetting my router, tried resetting my DMZ/UPnP settings. Tried to delete system cache, and various other tools including calling my ISP which for the chicagoland area is typically either comcast or at&t, I have the former and they have nothing to aid me in my quest to solve this annoying riddle.
If anyone may have an idea as to why this is happening, and why now of all times, the information would be appreciated, if it's just a new bit of the Live experience than I will use other means to be able to know when my friends are online/offline so i can have sessions with them inbetween countless hours of single-player antics.
As I have said, there are NO problems whatsoever with the service itself, just disconnects me when not using the service. party chat works, reconnecting works and multiplayer games (such as MW3, Street Fighter) all work fine online. But when I play Skyrim, Deus Ex, KoA:Reckoning , etc is disconnects me till I reconnect on my own or head to the dashboard.
