Same here Justin. You can look at my thread I made. I have Charter as well and was streaming a year straight no problems and now all of a sudden problems where it disconnects or lags my game.
Things I've tried:
Charter came over switch router, modem and all my lines.
Tried disabling my firewall.
Tried all different servers that were best for my connection
Tried minimizing network impact
Tried lowering bitrate to a crazy low.
Tried different streaming program = success
60 down 5 upload and I could stream at 3000 bitrate just fine and now I can't. I even drop it down to 1500 for shits and giggles and still lags my game and disconnects me. I stream on XSPLIT, no problem at all.
