Airplay and mirroring don't work

AirPlay

AirPlay Mirroring requires a second-generation Apple TV or later, and is supported on the following Mac models: iMac (Mid 2011 or newer), Mac mini (Mid 2011 or newer), MacBook Air (Mid 2011 or newer), and MacBook Pro (Early 2011 or newer).

Troubleshooting AirPlay and AirPlay Mirroring

Using AirPlay

I have a Late 2011 17inch MBP. Airplay mirroring has worked before, now it doesn't. When I mirror, I have mac audio. but the AppleTV video goes black.

I can Stream via "airplay" from my ipad and phone just fine. iTunes audio works as well.

I have restarted all devices. tried the firewall stuff etc.

NO, this is the most useless response, ever.

i have the same exact problem, with apple tv 2 second generation, latest firmware

ipad 1, iphone 5, iphone 4s, iphone 4, windows laptop itunes, all will not see airplay icon

apple tv is on, airplay is on, and functions such as netflix work on apple tv

help!!

I have replied to a previous post as I had the exact same problem.

AirPlay there this morning and not this afternoon.

Glad to say its back now AFTER reconnecting Apple TV back to Wifi(well re entered the pass code) and AirPlay icon is back as I type!

Hope this works for you

I got mine to work again by resetting my wifi, which is built-in to my modem so its way more annoying than resetting a router :(

Regretfully I am suffering a similar problem See https://discussions.apple.com/thread/4344794

Someone must have an answer!

kappy has useless answers!

You say your software is up to date, but is is OS X 10.8? If you have 10.7 it will say it is up to date, because that OS is but it is still not supporting mirror.. You will need 10.8 as a new OS to mirror which you would need to purchase from the app store.

The up to date software is probably the problem. Do this:

To downgrade, you'll need to download the previous software version here: ATV3 http://appldnld.apple.com/AppleTV/041-4361.20120605.grjot/AppleTV3,1_5.0.2_9B830 _Restore.ipsw

ATV2: http://appldnld.apple.com/AppleTV/041-4362.20120605.t8i4U/AppleTV2,1_5.0.2_9B830 _Restore.ipsw

Next, plug the Apple TV into your computer with a micro-usb cable (most phones today use these) and start up Itunes. It should detect the Apple TV in recovery.

After that, hold down Option on Apple or Alt on Windows and click Restore. This should open a window that allows you to select the software update you want to apply. Select the one you downloaded earlier.

It will then go through the restore process, which takes only a few minutes, and then you will be able to plug the Apple TV back in to your display and set it up again.

You will only have to do these steps once to recover the Apple TV, and it will give a message after it's done that it's ready to be set up again. After setup, make sure you don't update the software again.

I recently ran into a similar issue with a bunch of these things and after restoring them all to the previous software version they are working again.

I rebooted my router (Linksys E2000) and AirPlay is now working. First tried rebooting all AirPlay devices with no luck. Sadly, I have no explanation why rebooting the router solved the problem.

i have this problem, audio but not video from Airply Mirroring from an OSX device. My IOS devices work fine. My Mini i'm trying to mirro from is hard wired into a Linksys E2000 also, via a Netgear switch.

reboots on my Router did nothing. I'm really at a loss with this.. help, anyone?
