I am hoping someone here might be able to help me out. My wife and I signed up for Xbox Live over the summer so we could use HBOGO. Over the last few weeks we began experiencing difficulty staying connected to the Xbox live service. I updated our router firmware and tried moving the router right next to the xbox to no avail. We haven't noticed any issues connecting with other devices (two laptops and a desktop), in fact since we updated the firmware on the router the connections have been better than ever. Things have come to a head with our recent purchase of Halo 4, as the Spartan Ops and Matchmaking can't be played with our connection disconnecting every 10-15 minutes. We are feeling really frustrated by this and are crossing our fingers someone here might be able to share some insight.
