Apple TV won't airplay or mirror w/ any Apple device

Hi guys,

I have an Apple TV 2 and I'd like to use the airplay and mirroring features... Since that's why Apple TV is cool. I've connected all devices (including the Apple TV) to our home network. I've made sure that my Ipad 2, ipad mini, iphone 4 and my girlfriends iphone 5 have the latest software (6.x). Ive also updated the router's firmware and turned on airplay in the Apple TV settings. I just restarted my apple tv by going to settings>general>restart. I am not able to stream any video from these devices to my Apple TV mirroring , airplay or otherwise.

I've looked at the troubleshooting page here: http://www.apple.com/support/appletv/airplay/ with no results.

Does anyone have suggestions?

Thanks in advance.
