Airplay won't work through one of my Wi-Fi Networks
I'm trying to use Airplay and have an AppleTV and an iPhone 4S. The way my home network is set up is I have the main Wi-Fi network which is connected to my cable modem and is using an Airport Base Station Extreme. I have an additional home network which is in another part of the house where the AEBS does not work as well. That network is running on a Cisco/Linksys E3000.
The problem is if I connect both the Apple TV and my iPhone to the main network using the AEBS Airplay works fine. If I connect both devices to the other Wi-Fi network it doesn't work. I had the idea that as long as both devices are on the same Wi-Fi network it should work fine so this puzzles me. Since the Linksys E3000 network is stronger in that part of the house I would prefer to use that Wi-Fi network on the AppleTV and the iPhone.
Does Airplay require a AEBS? I had the idea it should work on any router.
Is there something I have to change in the settings for the E3000 to have it work with Airplay?
Thanks for your help.
