iTunes on PC unable to play on AVR and AppleTV connected to secondary router
Hi all, I hope I came to the right place to ask this question. I have a PC with iTunes installed in my study on the first floor. The PC is connected to Linksys router. My Marantz SR7012 receiver is located in the basement in my dedicated HT. I have a second router in my dedicated HT with the Marantz AVR connected to it for internet. My Apple TV 4K is also connected to this second router. An ethernet cable is connected between the two routers. Here is my problem:
-Airplay does not work on my receiver or the Apple TV. It sees the Marantz receiver and the Apple TV device but times out and cannot connect.
-If I plug my ethernet cable coming from the main router in the study into either the receiver or the AppleTV device airplay works for both.
So my question is: is there a way to configure the receiver and apple tv device to point directly to the main router in the study so airplay can work? Not sure how to do this but maybe somehow with changing the ip addresses on the receiver and apple tv? Or configuring the main router to somehow see the two devices? Any help would be appreciated.
