I have:

  • Windows 7 PC with latest version of iTunes connected to my network (wired). Windows Firewall is turned off.
  • Apple TV (2nd generation) connected to my network (wireless)
  • iPhone connected to my network (wireless)

I am able to AirPlay from my iPhone to the Apple TV, but it does not work from my PC.

In the Apple TV menu under Computers, I can see my computer's library but when I try to connect, it takes a while and then it fails. I don't see the Apple TV from iTunes on the PC. (I don't see the iPhone either under sharing but I don't know if it should show up there or not).

I don't think it's a router issue otherwise it wouldn't work with the iPhone either.

I have reinstalled iTunes on the PC and rebooted all devices (router, PC, Apple TV).

What do you think could be the problem?

  • I don't have an Apple TV, but I suspect the problem is that you need to initiate a wireless connection from the PC to the AppleTV. If the PC is not on the wireless network, then this is not possible.

  • I tried it wireless too from the PC. It does not work either.

  • Are all these devices on the same iTunes account?

  • If iTunes does not see the Apple TV they may not be on the same network. Do you have an AirPort (i.e. Apple-branded) router? There are certain features on AirPort routers that may create a separate network if not careful. Also, was an iTunes Library with the same name previously associated with that Apple TV? You may need to re-create the link between the Apple TV and the PC (on which case, you will need iTunes to find the Apple TV first).

This sounds like a home sharing issue to me. I would check that the Apple ID you have set in iTunes on your PC matches the ID you have configured for home sharing on the Apple TV and that the password is correct for both.

  • It could be - but it might be better to check that mDNS isn't being blocked before looking at a narrow cause. Your suggestion is faster to check than mine, though :-)

  • I'm sure it is the same ID and password.

  • Still worth checking

  • I did not mean I'm sure as I think so. I meant I'm sure as I know so. I only have one apple ID. And I turned Home Sharing off and reconfigured it again just to make really really sure.

Okay, AirTunes uses a protocol that is different from AirPlay mirroring, used by the iPhone.

The AirTunes part of the AirPlay protocol stack uses UDP for streaming audio and is based on the RTSP network control protocol.

What I would do first: 1) Turn off QoS or any protocol-dependent traffic shaping on your router. 2) All apple technologies are bonjour-dependent, I would check if there if there is an avahi service running on your router, using one of the following apps: http://hobbyistsoftware.com/bonjourbrowser http://www.stg.com/zeroconf_explorer.html

  • I turned off QoS on the router. Then I used Bonjour Browser and the Apple TV is not listed.

  • I have found another thread here discussions.apple.com/thread/2747237?start=0&tstart=0 that points toward an issue with my D655 router.

  • Enabling Multicast Streams (as mentioned in that thread in my previous comment) did not help.

  • After enabling multicast, you need to reboot both the router and AppleTV. Did you do it? Also, please tell me your firmware version. Also, please state the hardware revision in the upper right corner.

  • Yes I did reboot both. The Apple TV is still not showing in Bonjour Browser. The H/W Ver is A4 and I have the latest firmware installed (1.35).

The best way to troubleshoot this will be to get WinDump or some other tcpdump equivalent program and verify that the mDNS packets being broadcast by your Apple TV are being seen by client programs running on your PC. You can power cycle the Apple TV or just exit and re-join the network while capturing to ensure it's not a network or firewall issue.

Once that's decided, you can look into iTunes drivers or software conflicts or address the networking issue as your specific circumstances dictate.

  • I ran WinDump and it printed listening on device followed by a device name. I restarted the AppleTV (cold boot). Nothing came out in the WinDump window.

It seems everybody is having problems with this, including myself. You could try to:

  • Change wireless security from WPA to WEP (couldn't test)
  • Turn off wireless sync between your iDevices and iTunes (did no good)
  • Reinstall Bonjour (unistalling everything Apple/iTunes related and then installing iTunes again didn't help me)
  • Restart "Apple Mobile Device" service on your Windows computer (again no good)
  • Buy a Mac ;) - it seems it all comes down to this

  • Before downvoting, did any of you try the mentioned steps? There are claims they helped others. I resorted to the last solution.
