I just bought a new TV, speakers, and a Yamaha RX-v473 receiver. I got this receiver in part because it supports Airplay and I can play my iTunes music through the system. The receiver has Airplay, but no Wifi. I have an iMac, iPad, iPhone, and a wireless Canon printer. My internet is Via cable and the modem is plugged into an older model Airport Express. I think the receiver must be plugged into the network, but it is via Ethernet and the Airport Express has no ethernet-in other than the one which the modem is plugged into. There is what seems like a USB and a firewire in ports. Do I need to get a new router with more than one ethernet in? Or, do I get a new Airport Express, which I believe has both a WAN in and a LAN in. I want to keep the wi-fi network and enable the Airplay feature in the receiver with the least equipment as possible. Can anyone suggest the simplest most cost efficient method to accomplish this? I also want the ability to pull in radio stations from the Internet, like Pandora. I assume that accomplishing my first task will enable the second as well. BTW: I live in a small studio apartment, so the range of the network is not an issue; keeping the network secure and private is.
