Q: Apple TV update 5.1 broken?

I updated as well and now despite home sharing being on on both computers they do not show up on my apple tv.  This renders it useless since I have someone who is unable to walk and needs to be able to access many things via the tv. 

Any help?

Hi Janet.

I had this problem for ages too, and got no help from Apple.

I managed to fix it though. Not saying this will work for you, but it's worth a try.

For clarity, I have an Apple TV 2 updated to the latest system - 5.1 And I am using my late 2009 27" iMac (running Mountain Lion) to generate wifi from it's built-in card. I was fine with Home Sharing until 5.1, when it stopped working.

Anyway, I fixed it.

I went into System Preferences on my iMac. There, I clicked on 'Sharing', and then again on 'Internet Sharing', so I could go into 'Wifi options' down in the corner. When there, I clicked on the 'Security' dropdown. 5.1 means it only lists WPA2 Personal. But if you hold the option key and click the dropdown, you have a choice. I changed mine back to what it was before - 128-bit WEP. Then I entered the password, clicked 'OK', and re-checked the 'Internet sharing' box.

Now my Apple TV can see my iMac. It still seems a little slower when initially loading a film or TV programme, but it's reliable.

Let me know if this works, or if you have any questions. Good luck.

You solved my issue, I gotta give you big thanks!!

I have an Apple TV 3. 5.1 didn't really affect me much, as I use a Wi-Fi connection, but after updating to 5.1.1, I could no longer connect to Netflix, and couldn't get Hulu Plus to work either (although it did let me set up an account; one I quickly deleted). I tried these with ethernet, and they worked, but ethernet is impractical for me. I had to downgrade to 5.0.2 to get things working again. Instructions on how to do this are at https://discussions.apple.com/message/20008613#20008613

It seems 5.0.2 is still a signed update, and the downgrade went off without a hitch.

I reported this issue to Apple.

Everytime I try to turn airplay on to show my desktop screen on my apple tv I get the following error message:

Er heeft zich een fout (-6722) voorgedaan tijdens de verbinding met het AirPlay-apparaat 'Apple TV'

"An error has occurred (-6722) during the connection with the AirPlay-device 'Apple TV'

Anyone else having this problem?

This problem has occured since I updated to version 5.1 of the Apple TV
