AppleTV in corporate, WPA2-enterprise wifi networks

Hello,

I would like to use AppleTV in my institution's corporate WPA2 secure wifi network, in order to mirror my iPad. I am looking for a stable solution.

iOS devices require the installation of a profile. I have tried to install a profie in an AppleTV (2nd generation). I don't think the profile "stuck". Should a profile stay in the AppleTV, would iOS devices "see" the Apple TV across the secure network? Also, I've read that the problem is that first time the AppleTV tries to connect to the internet, it tries to set date and time, and it remains in there in a loop unless it sets it from a wired connection (then, it can connect to the wifi network)

Another solution would be using an Airport Express to distribute dynamic IP's to the AppleTV and the iOS devices. But, can a WPA2-enterprise profile be installed permanently in Airport Express?

Linking the AppleTV or the Airport Express to ethernet (RJ45 cable) is not viable: those are fixed IP's which must remained assigned only to desktop computers. The solution must be wifi to wifi.

I would greatly appreciate any suggestions.

Thank you very much,
