Maybe. Your router has a max wifi of 54mb/s. With wifi overhead, you are probably only going to see a max of around 25-30mb/s. That SHOULD be okay, assuming nothing else is using any of your wifi bandwidth AND your signal is strong with limited interference. Generally speaking I recommend N routers for video streaming, but I would say give it a try and if it doesn't work well (lots of studdering) then you will need to upgrade your router. Can you at least hardwire (ethernet run) your AppleTV? That would definitely help having only one "end" of the airplay on wifi.
