I have a 2013 Macbook Pro Retina, Nighthawk router, live in the country (no other wireless networks around me), have a 3rd generation Apple Tv. I went up to the sound icon in the Menu Bar and chose the Apple TV so that I could play some SoundCloud through it to my sound bar and all the thing does is lag every once and a while. I cannot figure out how to fix it. If it doesn't lag, it will just disconnect. Even when I mirror the screen to watch a movie, it lags like all hell. Any suggestions?
Here is a video of the lagging: http://youtu.be/CnkWXfOKc-E
