So I have a dual band Airport Extreme (simultaneous). My Mac is on the 5Ghz band and my ATV is on the 2.4Ghz band. When I put my ATV on the 5Ghz band the Airplay button in iTunes disappears. Go back to 2.4Ghz on my ATV and the button returns. I thought putting them both on the same band would mean a stronger signal as Airplay cuts out a lot and stutters. Sometimes it works fine but often times it doesn't and it's very frustrating. Any ideas? I really think the days of Apple products that "Just work" are over. I'm really not sure that a fully wireless world is the way to go. Wired connections will always trump wireless. It's tried, tested, and true.
