Persistent banjo errors yesterday (Sunday 3/29) and again this morning (3/30). Have done all the available troubleshooting and NAT is open, matchmaking, internet, and xbox live all available and trouble free. I can play other games online. I called Comcast this morning. Luckily, I had a tech that hosts minecraft servers and was willing to work with me to try and fix things since he understood how frustrating it can be not to be able to game. Had the guy on the phone for an hour and long story short, it isn't anything with my set up (already suspected that), nothing showing on Comcast's end (at least that he'd admit). So what does that leave? I don't know and don't have any answers. I've noted a bit more buffering while watching netflix in the past few days so that makes me suspect a bit more on the comcast side, but all his diagnostics indicated everything seemed ok on their end. Bungie, ball is in your court. Looks like I'll need to buy the Handsome Jack Collection on the way home.
