I bought a new Vizio sound bar and also ditched direct-tv. I set the sound bar in the center open slot of my tv console and set the Mi Box on top on the center of the sound bar. I started using my Logitech 650 with everything since I realized that day I could program to use the sound bar and Mi Box. So for the next few weeks I've been so damn frustrated with it buffering. I thought I was being throttled. Didn't seem so with other devices though. Updated router firmware and everything. It's 4 years old and so is my cable modem. I was pretty close to replacing both just because I'm so frustrated. I moved my Mi Box off the sound bar to the top of my tv stand today because I figured it might be getting to hot. Doesn't feel warm really but it damn sure worked. I'm not buffering at all anymore. Now I know heat isn't a friend to any electronic and I have my router and modem open so they get plenty of air. But my sound bar isn't putting off much heat.

Has anyone else had buffering/lag issues then realize it was getting hot? I hope this was definitely the issue and I'm not on some placebo high.

TL:DR heat may cause buffering issues. Try moving your Mi Box
