AirPlay from another AccessPoint
I have a question about AirPort Express and AirPlay from another AccessPoint on the same network.
The house is three floors, in it I have 1 router and 3 AccessPoint (all on the same network 192.168.1.x). Well, I'd buy an AirPort Express to use it on the first floor in AirPlay mode (audio connectors are on the first floor) ...
The question is how I can use AirPlay from the second or third floor connected to Wi-Fi from other AccessPoint?
