Airplay Apple TV not working/mirroring after IOS 8

Further testing...So I had to reset the network settings on all devices except ios 4.1.4 (which works perfectly) in order to get the Airplay icon to reappear. That didn't work, so I then manually told the router to forget all devices except ios 4.1.4 (which works perfectly). That didn't work. Reset the network settings again on each device and now the Airplay icon shows up.

Interestingly, if I set up an Airport Express/Extreme to distribute the wifi signal - the Airplay icon shows up on devices.

I now have a semi-stable setup where the device will refind the Airplay icon after disconnecting and reconnecting to network. I haven't reintroduced the ATV3 as I don't want to screw things up and don't fancy delving into the trash can to retrieve it. It's found a new home.

This issue still exists in iOS9 beta.

I also have El Capitan installed and airplay works fairly well. It's only when I switch to my iPhone 6 plus or my 1st gen iPad mini (both iOS9 beta) that the struggle begins.

I can often get it working by turning airplay on first, sliding the switch to turn on mirroring, and then turning on app I want to airplay. Sometimes I have to play with a bit by turning mirroring on and off a few times.

The problem is I would prefer not to use mirroring, it changes how video is displayed on my TV. Without mirroring I use the entire screen on my TV, not so with it on. Now sometimes I can switch mirroring off and it will work, but it's touch and go, and often what happens is that it will start "stuttering" like it's constantly stopping and starting. Thats when I switch back to mirroring.

I mainly use it for my sling player, however it's even worse with apps like CBC TV, which has ads placed periodically in its video stream. Every time you hit a commercial, airplay gets screwed up.

Interestingly, when I use the Youtube app and "airplay" to the TV with the built-in wifi-direct it works great. How google can get their apps to "airplay" better than apple is beyond me.

This total worked... I have been so ****** off about this because I use airplay for school so I can watch my lecture videos..

Thank you times 1000 Jhbogie...

Update: Further playing...

my issue related to compatability between 3rd party wireless extender and Apple Airplay. When wifi extender is connected to network (regardless of any devices being connected to it or not), Airplay gets screwed up, sometimes works and sometimes doesn't, even with devices that are hardwired to the router and not using wifi. (How's that?!) Disconnect the extender and all Airplay issues go away.

What's strange is that device running iOS 4.1.4 never had any issues and always worked.

Guess I need to put my Extreme and Express's back into service.

After trying everything suggested here I reset my wifi router and "hey-presto" airplay back on iPhone 4 and iPad 2.

IF the plcture is frozen try using your Apple TV remote ie the play button.

Reset network settings on the offending i-devices has since fixed ALL of my ios networking issues relating to airplay, dropouts, adding new networks etc. I had a customer with the same wifi extending issues as you and this fixed that.

for me it's weird all of my devices work expect my IPhone 6 on my ATV 2. The phone it's on IOS 9.2.1 and it works on my ATV 3 but not ATV 2. On the ATV 2 it has a weird icon, it's different from the ATV 3. The ATV 2 and Living room ATV is the same thing. When i try to use AirPlay the audio just mutes on the phone and nothing comes from the ATV no sound and no video.
