Hi all, I just upgraded to the latest airport extreme. Before i had a Linksys Ea4500. I am currently facing and issue with airplay. I have apple Tv and Denon 1913 receiver which also has airplay. With the Linksys router, i was able to see the airplay option whenever the denon and apple was in sleep mode. Now, with the airport extreme, i can't see the airplay icon on my iphone, mac, and ipad when those devices are in sleep mode. Is there anything i have to do? When i turn on the denon or apple tv, the airplay icon shows up.
