Yesterday I left the house for a few hours and came back and my Xbox One would no longer connect to Live. I've forced a hard reboot a dozen times and even reset the modem/router back to its default settings and still no dice. Tried deleting profile and downloading it again. The built in network/multiplayer tests both say everything is good and I can see the friends list and the Newsfeed but when I return to the home screen it still says I need to connect to Live. I have a laptop two feet away streaming HD video so it shouldn't be the wireless connection alone. Intermittently I can't even sign in to the system at all. Any ideas?
