I have a Roku
My Model Number is "Roku 2 XD" 3050X it's wireless and I have no problems with it when I did nextflix. However I also on an Apple TV and just to let you know if your thinking about the roku I would maybe give Apple TV a try over Roku because I think quality of video is much better on an Apple TV but this just my opinion. I hope I helped! But the roku is okay!
