Apple Tv Router Compatibility?

On my old router I could use AirPlay instantly between my Apple TV and Apple devices. I recently purchased the Belkin N750 DB N+ router and now I am having issues using AirPlay. When I go to send a video from my iPad to my AppleTv my iPad can't find all of my Apple Tv's, with all of them turned on it may reconize half if i'm lucky. On my Apple Tv it doen't always find my iMac.

I think this is an issue with the router. I have turned off the firewall and still get the same result. Does anyone know if their are any routers under $100 that is combatiable with Apple AirPlay?
