iPad 2 & Apple TV 3rd Gen - Airplay not working
I have an iPad 2 and 3rd gen AppleTV. When connecting to the network at my house with the Apple TV and iPad 2, it works flawlessly. I am able to use Airplay and mirror the image onto my TV. Here is the tricky part of the equation... When I bring the Apple TV into my classroom at school, I am not able to have the airplay button display on my iPad 2 when they are both connected to the same network. I have tried following the restarting steps and everything, to no avail. I have read about the problems Apple TV can have on certain networks, especially those found in school classrooms, but here is the kicker... I brought in a coworker's iPad Mini and the Airplay icon popped up right away. I also am able to have the airplay button display on my iPhone 5. What am I missing? What is the big difference from the iPad 2 to the mini and iPhone 5 that allows airplay to work on the network?
