I have read over the past week the problems people have been having configuring their Apple TV and Home Sharing. I was experiencing the same issues as others....until tonight. I finally got it to work with an Ethernet connection. Previously, I was only able to get it to work via wifi and home sharing would drop after awhile.


1) Xfinity router settings. Like others I was suspicious if the Xfinity router was causing the issues because of the separation between wifi network and Ethernet network. It's not the router problem. I disabled the firewall. Enabled port forwarding. Gave a static IP address to the Apple TV. Added forwarding of ports

   123 TCP

    3689 UDP (all other support says this should be TCP but searched through and found a thread that suggested changing to UDP...this was the key)

    5353 UDP

    80 TCP

    443 TCP

    53 TCP


DMZ is off

Device discovery is disabled

Port triggering is disabled.


The wifi is setup and functional using DHCP. Lease time is 1 week.




2) Mac computer. As of this posting the latest version of iTunes installed. Latest Safari version. All programs updated. Turned on Home Sharing. Turned off firewall. Gave Mac a static IP address. Set Mac for hard drive to never sleep. Set monitor to sleep after 15 minutes. Set date and time to automatically find based upon time zone. ( Apple TV needs to be set to the same time zone as computer and set to manual). Enabled file sharing amongst users on Mac.


3) Apple TV. Ethernet connection. Configured TCP/IP to static IP address  I configured on router for the Apple TV. Turned on AirPlay. Set date and time to manual and set as the same time zone as the computer with iTunes. Turned on Home Sharing. Using latest version of Apple TV.


Once the router was reset ( not restored and not just resetting the wifi. A complete router reset), the Apple TV found my iTunes library. It's been running now for over an hour and no drop in the home sharing. Working beautifully. I will be testing in the next couple days allowing the Apple TV to sleep, turning the firewall on the router to a minimal setting to see if it changes anything.


Just tested the AirPlay from my iPad 2 to the Apple TV while the Apple TV is connected via ethernet connection and it works. At this point it appears that the setup is correct and complete with no errors.


As a side note, the Ethernet connection between my router and Mac is via commercial devices using the power outlets as the wiring.


Hope this helps many of you that were/ are struggling to get this to work like I was.

    Hey, thanks for posting to my issue, they do look similar.  Tell me, do you think ALL the steps above are required, or Just the hard reset of the router?  And how did you do that exactly?

    Thank you! My Apple TV is usable again! It is responsive and plays music (what a concept)!

    I experienced a similar problem of Apple TV not connecting to the library from one of the Mac computers on my network . I have wifi connections (not ethernet). After two days of struggling , i just recycled power to the apple TV and Lo and Behold , back connected to the Library.

    So what you're really saying here is that the update from Apple is complete garbage. Apple TV was supposed to be the next great thing. The only way to access and/or rent movies, music, TV shows,etc. The greatest thing since Vimeo and Youtube. It was supposed to be EASY. And it was UNTIL THIS NEW UPDATE. PLEASE APPLE read what these guys are doing to work around your stupidity and implement it into a new fix. Otherwise employ SPMA3 at Apple. He seems to know way more than you do.

    Hi spma3,


    Seems like this is one of the first real resolutions that I have seen (lots of different threads on this home sharing issue). 


    I have been having the same issues with home sharing and Apple TV2s (I have 3 of them).  However, I am Win 7 (64 bit).  Seems like what you did to rectify this issue is only for Mac.  Have you seen a similar work around for Win 7 (64 bit)?

    Not sure that I understand why port forwarding is necessary. According to my Cisco RVS4000 Router's Help page on this topic, Single Port Forwarding is used when one wants to open a specific port so external users can see servers behind the Gateway. So given that Home Sharing should allow my PC, my wife's iPad2 and my ATV2 (which are all wired on my domestic LAN) to share, I cannot see how spma3's action actually fixes anything! Home Sharing is intermittent for me, with the symptoms as per lots of other peeps in this thread.


    In my case, I can sometimes play music via the ATV2 from the PC's iTunes Library, but it will just stop. Sometimes AirPlay Mirroring of the iPad2 works, and I can view photos off my NAS. But just not all the time. So basically I have seen what the ATV2 is capable of doing, but just cannot get it to be consistent.


    Given that Apple products "just work", I think Apple itself needs to fix this. And it is very similar to the AWOL problems I had with two AEX boxes. Eventually I gave up with these, and bought a Sonos system for my streaming audio. It "just works" 100% of the time!

    Appreciate your further message. As you say "it's not fixed", but at least your solution appears to be a viable workaround!


    My Cisco RVS4000 Router will permit me to forward ports for up to 15 applications. Of these, thirteen already have default entries added, although none of these are presently Enabled. For example, here's just 2 lines...

    Application           HTTP        NTP

    External Port          80           123

    Internal Port           80            123

    Protocol                TCP          UDP

    IP Address            No entries at both

    and the Enabled box for both is unchecked. In fact none of these 13 possibilities is Enabled.


    To do what you are advising, I would need to...

    1) Enable the above Port 123 entry, changing it from UDP-->TCP.

    2) Add new entries for 3689 UDP & 5353 UDP... using the two free slots at the end of the table.

    3) Select three of the default entries, and reconfigure them for 80 TCP; 443 TCP; 53 TCP, all as per your guidance. And Enable them.


    Now, my present setup here has...

    1) My PC is wired straight to Port 2 of the Router, and has a Static IP Address set.

    My new ATV2 is hard-wired into the same subnet, albeit thru a series of switches, and again a Static IP is set. My understanding is that hard wiring an ATV automatically disables its WiFi.

    3) My wife's iPad2 is set for DHCP, so it can pick up an IP Address when on the move. It connects into the LAN using one of two WAP4410N Wireless Access Points. Ch-1 & Ch-6, with same SSID and security stuff set up on both. The WAPs in turn are wired in, again with Static IPs set. So depending where she is in the property she can connect with excellent signal strength, reaching the ATV2  by WiFi+LAN.


    On the Router DMZ is OFF, Port Range Triggering has no entries, nothing is Enabled, so is OFF. No idea about Device Discovery!


    Home Sharing is ON for the PC, ATV2 and iPad2, with the same Apple ID/Password set for each. It does work, just not consistently as it should.


    So to fully implement your idea, all I need to do is to enter these details. But I am unclear which IP Address I should put in at each new Single Port Forwarding entry field. Certainly not the iPad2, as its DHCP allocated value will change. Is it the ATV2 or the PC? Not sure, please clarify.


    BTW, I have no plan to deactivate my AVG Firewall on this PC. It is happy to pass all traffic related to iTunes, so cannot see this as a factor. Time zone same on all equipment.


    I tried with just 3689 UDP and 5353 UDP yesterday, and things were definitely better. I used, the IP Address for the ATV2.


    Look forward to your answer.

    Many thanks again spma3. Did as you said, but the iPad2 would no longer connect to the internet. Rebooted router - same. Rebooted WAPs in turn, connection came back after first was ready.


    I have restored my router as it was for now, as I have no more time to spend on this today! Will repeat the process ASAP, taking more care, and doing just one small step at a time to identify which port change may be causing this here. Will advise findings ASAP.
