I'm so fed up. This has been going on for about a year now, and no one seems to be able to help me. Xbox support suggests that it could be my cable provider (Comcast), as we our testing shows that I can indeed connect to XBL just fine. [I have the TC8305C modem box by the way. I think it was this switch that made it worse? Not sure.]
Anywhere from just a few minutes to maybe an hour of online play, I'm disconnected from XBL. I can do anything else on XB just fine (Hulu, Youtube, play offline, etc) rarely ever being signed out of XBL. It's extremely frustrating, especially when I'm grinding to level up and treasure hunt on Destiny.
I've contacted Comcast, and they don't seem to know squat about what to do, other than what may already be on their computer. A lot of my friends say it can be an IP or NAT problem, or something about firewall restrictions, but I have no idea how that stuff works. I've looked it up, and have followed sorts of odd instructions, but nothing helps?
I'm pulling my hair out at this point, I just want to play! Does anyone have any advice?
