I just got my SC-57 but cannot get airplay to work. I know the receiver is connected to the network properly (using a LAN cable) because I can use internet radio and I can even control the receiver with the iControlAV2 app on my iphone. So I think the problem is with my isp provided modem/router combo. I cannot seem to figure out what port or ports i have to open for my router to allow airplay to work. My isp is Rogers and the modem I'm using is a Cisco DPC3825. Any help would be appreciated.
