I have a new MS wireless display adapter plugged into my TV (HDMI and USB plug). Also a new Surface pro 3. After a short period of time, it just disconnects. Especially when watching a movie. The audio/video gets choppy for a bit and then it disconnects. I'm about 10-12 feet away.
Installed wireless adapter app from windows store, but that didn't help.

The wireless internet router sits on the same table next to the TV. I moved it a couple feet away and was then able to watch the entire movie without it disconnecting. Maybe that was it.
