I've got an apple tv 3, iPhone 6, and airport extreme n, I think dual band. For the longest time I've been disappointed with Airplay. I was hoping the hardware update (from iPhone 5 to 6) and software updates would fix the problem, but it has not. Video seems ok (but not great), but I am having the worst experience with audio when I really shouldn't. Signal Strength is 4/5. ITunes Radio works fine, but if I attempt to stream an Rdio/spotify playlist forget it. Constant stuttering, after a few tracks it just gives up. Would upgrading the router help? Or is there a setting I should look at? I know it won't take full advantage of an ac router, but might it help? I think I'm also done with the Apple routers. I'm ready to give up on the hardware altogether. I've owned every gen of apple TV, but the lack of audio apps, speed, airplay issues is pushing me towards the other available options.
