Airplay won't work through one of my Wi-Fi Networks

by markw10 / February 24, 2012 5:29 PM PST

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.

Clarification Request
Are these two separate networks or
by mrmacfixit Forum moderator / February 24, 2012 10:47 PM PST

does the Linksys just extend the existing AEBS wireless network?

Where does the Linksys get its data from?

Airplay does not require an AEBS to work.

The AEBS has a neat function on it that allows it to chain together other Wireless access points. It only works with Airport Express and functions but allowing the AE to connect to the AEBS wifi signal and rebroadcast it.
This does away with the need to run ethernet cable to the location of the second wireless point, which I assume you have done, as the AE just plugs into an electrical wall outlet.

Answers to the first two questions will probably determine where you go from here.

Both networks are distinct. My 2nd router, the Cisco/Linksys E3000 is plugged into a Gigabit hub and that Gigabit hub is connected by wire to the AEBS that's in the basement of the house. The way it is set up is they are treated as two distinct networks. For example I have a printer that's hooked to the AEBS and any computer connected to the AEBS can see and print to it but computers connected to the Linksys E3000 can't see it. I would say this is what's causing the problem but yet if both the AppleTV and iPhone are connected to the E3000 it seems that even though it is distinct from the AEBS that it would not cause a problem.
Now someone has suggested I try a firmware on the E3000 and not sure if it will fix it but it shouldn't hurt anything. I like what you described about the Airport Express. The problem is the home office is in the basement where the AEBS is and my wife also works in that office so that's where most of the computers and printers are. The reason I have the 2nd wifi network is that the AEBS signal does reach to the main level of the house but is not strong in all sections of the house so for good coverage and speed I put a 2nd wifi network there for devices such as iPhones and iPads and of course the AppleTV.

Wireless network.

This is how we set up our Internet Cafe at the hospital where I work.

Incoming Cable > Cable Modem > PIX501 (Firewall, Router and DHCP Server) > ethernet to various locations in the hospital.
At each of the locations there is a Linksys Wireless Router.
Ethernet Cable, from the PIX, goes into one of the ethernet ports on the back of the Linksys. (NOT the Internet In port)
The Linksys is configured to have a Static IP address, its DHCP router capability is turned OFF, the SSID is whatever you want.

Repeat the process for all the other locations in the Hospital, changing the SSID to reflect the portion of the network that they are connected to, and you have yourself a network where everything can access everything but, the network is really just one big one.
Alternatively, make all the SSID's the same and you have exactly the same network but only one name.

The Linksys Wireless Router is now, effectively, just a Wireless Access Point. (We went that route because funds for the project were limited and Wireless Access Points are more expensive than Wireless Routers)
Users joining the wireless network get their IP address from the PIX.

With only one extra router, this method would make your two networks into one and allow everything to communicate nicely.

Our hospital does not charge patients for any of their stay, surgery, rehab and follow up visits, hence the shortage of funds for this type of project.

That help?

I have a telus actiontec modem/router/optik tv gateway and could not get airplay to work. My wireless setup was using WPA/WPA2 encryption. The home sharing only worked with my PC and Apple TV when they were connected to ethernet so I knew there was something going on with the wireless side and Apple TV.

I disabled WPS in the advanced wireless setup and Aiplay instanly started working. I have seen WPS as an option on some Linksis/Cisco home routers. I am not sure what WPS accomplishes in terms of security if you already have WPA/WPA2 encryption, but I am guessing not a lot on a home network.

Hope this helps.

With your permission, I'll add this to the sticky notes as something to try on other makes.
