Troubleshooting AirPlay and AirPlay Mirroring

Using AirPlay

Do you have multiple Wireless networks setup for your house (ie one for guests and one for family)?

I do, and I had problems getting it working. Then I realized that to get airplay working, both devices have to be on the same wifi network (apple tv and whatever else).

Hope that helps! 

Same problem. Just bought a brand new Apple TV. Mirroring only works for one second then Airplay disconnects the clients. I've got iPad 3 running the latest iOS 6 and updated Apple TV to run the latest iOS 5.1. Other video streaming from youtube etc on the iPad does work over airplay. I've got a 802n wifi network with strong signal covering both iPad and Apple TV. I'd love to find a solution if anyone knows how.

This article may be worth a read for you.  It could be interference on your signal.

I'm having the same problem ATV 2, iPad 2 and iPhone 3gS.  Remote app/ Aiplay not working.  No probs with the shared wi-fi and all OS isnthe latest and greatest.  Not feeling the love for OS 6 at the moment, after being misdirected across Europe by the new Map App...Oh well, guess I'll get used to it and wonder how I ever did without.

OK took a closer look at the posts with Green Ticks (Check Marks to those down in the Northern Hemisphere).  Simple fix: Restart Wifi router. Voila Airplay On!

I just ad the same problem. I plugged in the ethernet cable to my Apple TV and that worked for me.

My Apple TV was driving me nuts. I have a brand new 3rd generation Apple TV and a 15" Macbook Pro Retina and an iPad 3. My iPad was mirroring just fine. It'd show up on my telvision no problem, but my Macbook would not. Whenever I tried to get it to connect to my Apple TV, my Macbook would respond by switching screen types, but my TV would either do nothing, go black, or after about 10 seconds throw up a static picture of some image of my desktop. The sound would come through just fine, but that was it.

I tried all the "helpful" hints offered on the Apple site, but nothing worked. I even tried moving some files from my Launch folders in the systems library, but nothing helped. Then after what felt like weeks of work I tried the obvious. My Apple TV was on a wireless network, so I bought an ethernet cord and plugged it into the Apple TV and my router. Now it streams perfectly.

Score on for the Ethernet cord, huh?

AirPlay mirroring is not working properly between my iPad 3 and apple TV2. I get sound on the TV but no picture. The picture is on the iPad.

I have another IPad3 and when I use airplay on that device with the same Apple TV. It works perfectly. So the fault is on the IPad side.

I have updated the software, turned off Bluetooth but the problem remain. How can I solve it?

Kill the AirPlayUI process in task manager, so retry

You need to disable WMM on your router. This feature is usually accessible from the menu "Applications and Gaming" > "QoS" (Quality of Service).

Restart your stuff and you should be alright!
