Equipment: Netgear Nighthawk R7000, Yamaha RX-V675,Norton Security 1/2016, iTunes 12.3.2 on Windows 7 Professional 64 Bit.
Setup: My receiver is hardwired to the network, not wireless so I am pretty sure it's not a connection issue since I can still use Yamaha App to control the receiver.
Airplay used to work just fine so long as I initiated contact to the receive from my computer, the receiver popped up as an additional set of speakers. Once the connection was established. BTW It stopped working long before I upgraded Norton a couple of days ago.
I am just guessing that it has something to do with Norton because I haven't changed any settings in the router. I imagine that there's something that I need within the traffic settings. Any thoughts or ideas would be appreciated, thanks in advance
