I have the reverse situation. Everything was rock-solid until I upgraded to Snow Leopard, then my ATVs started dropping off iTunes like flies. I have an ethernet network, so everything's hard-wired, and still they disappear. It's really starting to annoy me.

They all come back on when I restart iTunes, then drop almost instantly, while still being shown under "Devices" in the sidebar.

Exactly the same for me, my Apple TV has been stable as a rock for 10 months, Ive been pretty much streaming everything from my Mac as the connection has been so solid. Then shortly after upgrading to 10.6.1 and just after installing iTunes 9 my Apple TV started dropping out of itunes almost immediately, streaming was impossible, syncing was impossible, the thing was useless.


Basically, if you get your wireless network stable, the Apple TV issue with dropping from iTunes will just disappear.

I agree, at the time I had a Linksys WRT54G running my network and I'd just added an Airport Express near the appleTV which was set to 'join the network' as a bridge for my xbox. Disconnecting the express had no effect, drop outs still occurred. I then tried disconnecting the Linksys and tested running the network (N) from the Express. This fixed the issue and I was able to get a full sync of 150g in one go. I've since purchased an Airport Extreme to replace the Linksys and the Apple TV connection and my wireless has been absolutely rock solid without a single dropout ever since (I'm running it dual with the Apple TV connected via N at 5ghz and my iMac wired directly to the Extreme). This was before the latest 9.01 iTunes update, its been stable with that since.
 
The point I was trying to make was that some people seemed to think this issue was definitely due to wireless. I was just trying to point out that I've removed wireless from the equation and still occassionally had this problem, so its worth looking at other things as well. On the flip side of the coin, you may find that in your case it is due to wireless.

I agree there is an iTunes component too or it wouldn't take resetting one or the other to make it reappear again. It shouldn't drop it period due to any kind of interference or any other reason. Why would it reappear with a restart if there wasn't a software issue there? On the other hand, I was just saying in my experience, the connection IS important also because I was having all kinds of problems with it getting dropped by iTunes like every other day and at first I thought it was all iTunes fault but then found that changing the network channel stabilized it completely (as in it can run weeks without dropping now). I've had a few iTunes versions upgrades since then (running 9.0 at the moment; haven't upgraded to 9.0.1 yet) and everything seems fine now. The only problem I had with iTunes 9.0 is that HD movies will crash my PPC machine every time (it never could run them smoothly, but choppy never equaled a crash before; in both cases they run fine on my Apple TV units streamed from the machine).

I'm curious if there's any difference for those running their Apple TV units off a Windows machine running iTunes or if the problem has been Mac specific. I've got a PC with iTunes, but I've never sync'ed off it, just as an extra shared machine like with my MBP. My PowerMac runs the whole house server with dual internal 1.5TB drives (both with and without iTunes as I run XBMC off the AppleTV as well for extra content). I just wish the ATV had more power so higher bit-rates for HD and 1080P weren't an issue into the future. An update to the hardware would be handy. I'd buy at least one newer one for the main theater room (and move the older one to an extra room). But I gather Apple never intended us to be ripping our own DVDs and BD discs to watch around the house. But given they offer jack squat in terms for HD movies to BUY, they shouldn't be kidding themselves either. Their non-HD movies are too inconsistent for me to ever buy. The DVD is almost always better and probably costs less. It's not that much bother to rip it and I can include the Dolby Digital soundtrack and even commentary tracks that iTunes purchased SD movies never provide. You'd think they could at least get with the times and offer Dolby Digital on non-HD purchases. Who wants just stereo in 2009?
 
I think I have fixed this problem, or at least solved this for me. I made a video about it on my website http://thecheapgeek.org

I have had this problem both when connecting with wireless to the apple tv and a hard wire connection. This issue was much more prevalent on wifi but still occasionally happened under a hard connection. After some research it seemed to me that the dropout happened at similar times to the dhcp lease renewing on the device. I even forced a manual renewal and the apple tv dropped out of itunes.

My solution is to simple set the apple tv and the computer streaming to it to a manual ip address on your home network. Since I did this neither of my two apple tv's have dropped out in almost 2.5 weeks. I am running itunes 9.01 and snow leopard 10.6.1. I have a wired connection to my iMac and a wireless g signal to both apple tv's from a basic linksys wrt110 router.

This sounded like a great solution, but I'm sorry to report that it didn't work for me. I set my iMac and my AppleTV both use static IP addresses and I lost the AppleTV in a matter of hours.

Is there anything else I should have done? Any settings on the Airport Extreme, for example?

Man that sucks, the only thing I didn't mention is my DNS settings, I use open DNS but that would have no effect on streaming. That is all I can tell you, I had daily, sometimes hourly dropouts, and the static ip addresses fix all my problems. I will keep looking for another solution.
 
My problem is not so much dropouts as it is that the :apple:TV simply won't show up at all in 10.5.8 Leopard but always shows up in 10.6.1 SL. Granted I am on iTunes 9.0.1 on Leopard, and 9 on SL. I am afraid to upgrade the iTunes on SL since it is working at the moment.

I even went ahead and reserved the static IP addresses in question on the Airport Extreme. But every morning, I wake up and check...and the AppleTV is gone from iTunes' Devices list.

Any other thoughts would be appreciated. This is enormously frustrating.

Oh, are you using a wireless n network? I have an old iBook, so I have to use b/g compatibility. That's the only thing I can think of that I haven't tried.
 
I 'll tell you what. I've been watching forum talk about this problem for some time. I have the same problem with my atv. it never ever shows up, and it hasn't for probably a year. not even for a few secs. I've tried every solution suggested, even followed instructions on apple support page. This reason is why this product will always be labeled a hobby. Since I own a G5 iMac, I 'll never know if SL would solve the problem


I just thought of something, that I'm also guilty of. I'm like lots of owners who don't like the fact there isn't an off switch and if you leave it on it gets very hot. Do you think there is a chance the problem with atv dropping all the time, occurs if you unplug it frequently?

Let me put your mind at ease on that score: I've upgraded to SL and it hasn't solved the problem for me.

I rarely if ever unplug my AppleTV and I still have the drop-out problem.
 
I think all you can do if you have this problem is try and eliminate each element in the chain. While its not guaranteed to be a fix, some things do seem to help with some people's setup.

Update all firmwares. If you're wireless, try different channels, eliminate interference etc. Try wired if you're wireless. Try static IPs instead of DHCP. Break the connection to the library, then re-establish. Restore ATV as a last resort. Etc.

For example, I lost mine again at the weekend after a couple of good weeks, but all I had to do was break the connection to the library and re-establish it.

Sorry, but I did every one of those things you suggest and none of them ever bought me more than, say, 12 hours of a stable connection.

I'm thinking of doing factory restores on both the Airport Extreme and the AppleTV, but the time it will take and the general annoyance have prevented me so far.

I have a wireless g only network, The only other difference I could think of would be that I only have one computer running on the network, meaning only one copy of iTunes. Maybe a second instance of iTunes open on the network cause the apple tv to freak out. How often to you open and close iTunes? Mine is running 24 hrs a day, I never close it. I want to get a airport extreme but the fact that my setup works makes question that thought.
 
found a solution

I figured out how to solve this problem. I'm selling my appletv! I love it, but I'm tired of this problem and I can watch all my content on my imac.

This is the last time I spend my hard earned money on something Apple calls a "Hobby". I should have known better. maybe this is what happens when you love their products, you become blind.

I leave iTunes running pretty much 24/7 (except when I'm restarting it to get the AppleTV back, natch!). I have one other computer on the network, a laptop that rarely -- if ever -- has iTunes open. I also have a wireless printer and a wireless Xbox 360, but both of these were up and running long before the drop-out problem started.
 
Happens with Windows XP, too

It's definitely not (solely) a MAC OS issue. I'm running the current version of Windows XP on a Lenovo T61 and I have iTunes 9.0.1.8 for Windows. Bought ATV 160GB last week and have been playing with it. When it works, it's great Although I hate the way it won't let me drag and drop media files onto it like my iPod, I was prepared to live with that moronic design because I need a wirelsss multi-room audio server that will play lossless audio, and ATV is really the only player.

Unfortunately, I too have been struggling with ATV disappearing from iTunes for no good reason. Apple's suggestions to fix it are absolutely ridiculous. E.g., restart ATV, restart the wireless router, restart the computer, REINSTALL ITUNES?!?!?! Are you f__ kidding me?

What a piece of crap. I'm finally giving up after days of trying to make it work. I don't have time to reinstall the damn iTunes software whenever I want to (temporarily) regain the privilege of using the stupid sync method of transferring my audio files from my laptop to the ATV.

Shame on Apple. If this product is where Apple is headed, it's already jumped the shark.
 
Success...?

Given the fits and starts with this problem, I don't want to celebrate too soon, but I may have something of a solution.

While fixing something ELSE on my network, I may have stumbled upon a solution.

I had already tried changing channels, mucking with interference robustness, establishing static IP address, and reserving IP addresses from the Airport Extreme.

Two nights ago, I switched security from "WPA2 Personal" to "WPA/WPA2 Personal."

No drop-outs since.

It's only been a little more than 24 hours, but this is the first time I've gone longer than, say, 15 hours without a drop-out. I am cautiously not pessimistic. :)

Why are they "ridiculous" ? Restarting ATV (better yet a hacked one just select "restart finder" and you're done) usually will bring the connection back if you've lost it (or alternately restarting iTunes). That's not a good explanation of WHY you lost it in the first place, but it's good advice on how to get it back, in my experience. Like I said earlier, once I found a good connection channel, all my issues disappeared and both of my two ATV units have solid 24/7 connections.

You can also run XBMC on a hacked unit and it will operate regardless of any connection in iTunes. Just enable SMB sharing and point it to your iTunes music folders and/or any movie folders. XBMC can handle things like MKV files with DTS support (I use it to watch my DTS only DVD files encoded to MKV such as Jurassic Park DTS).

Basically, any other unit out there you might buy is going to function like XBMC does on a hacked Apple TV (although some will have better HD support). Saying Apple TV is junk without taking that into account defeats the point. No other unit out there will sync with iTunes to begin with. If you don't like iTunes, why not install XBMC? It only takes a few minutes to hack an AppleTV with a USB dongle. It's so easy (with something like ATV Creator or equivalent) that it'd be pretty hard to screw it up.

It's ridiculous to tell users to reinstall iTunes to fix a problem that Apple should just figure out and fix. Sounds a lot like Microsoft's approach. The fact that Apple -- and everyone else -- has come up with more than a half dozen ways to "fix" something -- none of which work for everyone -- is a good indication that there's something seriously wrong with the product.

I've done everything suggested in this forum and by Apple but switch to static IPs and reinstall iTunes. Yet iTunes still refuses to recognize my week-old ATV. (I have another copy of iTunes running on a Powerbook, and it can't see the ATV either.) Every other networked device in my home network works just fine, including an Airport Express. You plug it in, it should work. Period.

You can also run XBMC on a hacked unit and it will operate regardless of any connection in iTunes . . . . If you don't like iTunes, why not install XBMC? It only takes a few minutes to hack an AppleTV with a USB dongle. It's so easy (with something like ATV Creator or equivalent) that it'd be pretty hard to screw it up.

Sounds easy enough. But: (1) I think I should be able to buy a consumer product and have it work as advertised, no hacking required; and (2) I've heard the mother ship periodically resets hacked ATVs to the default configuration. If that's still true, hacking doesn't seem worth the hassle.

You're not saying it doesn't recognize the unit and before you said it had a dropping problem. Which is it? There's a big difference there. You're not providing much information in regards to the unit itself and its connection ot the Internet. You say other devices "just work" but all devices have to be connected to a network first before they can do anything. Wireless networks need to be assigned. How does your ATV fare on its own? Can it see the iTunes store and its contents? Does YouTube function normally? Do Podcasts work? All these can function without ANY connection to another computer or iTunes. If they're not working normally, then there's a connection problem with your unit to your own router in which case nothing will see them. Networks are strange things. I had a power outage the other day and when everything came back up, my Mac wasn't connected to the Internet (I had to manually assign it its former IP address first for reasons unknown) and neither Apple TV unit showed up or one of my printers. All the devices had to be reset and restarted (some where backed up with UPS units; I have three computers, two printers, two networks (one routed through the ethernet switch on the other Network) and numerous wireless devices. Some devices had to be reset. Once the router could see everything and the Mac had a proper connection to the router, it could THEN and ONLY THEN see all the other devices. What I'm saying is sometimes there's a problem where you wouldn't expect one. Why shouldn't the network come back up normally after a power outage? I've had my NetGear router go wonky for no reason on the wireless channel but still function on the Ethernet channels and the only thing that fixes it then is a hard reset. Why? Who knows. There's a bug somewhere in the firmware that only occurs once every few months or so...sometimes longer. I've had XBMC running on Apple TV act all choppy when connected to an Airport Express, but function PERFECTLY when connected via the NetGear router (Apple's software works fine with either one). Why? I have no idea. Apple is well known for weird networking issues with their Airport devices (just look some time at all the posts about them dropping Macbooks and other such issues) so I shouldn't feel totally surprised that an Apple TV unit using similar internal hardware might trip up, especially on one of Apple's routers.

Sounds a lot like Microsoft's approach. The fact that Apple -- and everyone else -- has come up with more than a half dozen ways to "fix" something -- none of which work for everyone -- is a good indication that there's something seriously wrong with the product.

Well, it works fine here and I'm using an old PowerMac as my server. It worked fine under Tiger and it works fine now under Leopard on the same machine. I've used every version of iTunes from 7.x to the latest 9.0.1 and its worked without issue on every single one of them. I also have iTunes set up on my MBP running Leopard and my PC running XP with those same versions as secondary shared devices with iTunes and both of my two Apple TV units show up on every one of them without exception. Now if I can own two Apple TV units and have them function reliably on three different computers (a PPC PowerMac, an Intel MBP and an AMD powered PC running XP) I would have to say the problem lies in your system somewhere and it's not the computer if two of them cannot see it. It's your network somewhere/somehow.

What router/wireless networks are you using (brand/model/type of network)? What type of encryption did you select in the router to use with the Apple TV? I'm using WPA2 (AES) and it works fine. I've heard it might not work reliably with every method. I've reserved it and all my regular network devices static IP addresses on my own home network because I've had devices try to usurp an existing address and knock that device off the network before (i.e. my iPod Touch would log on to the network and grab the spot my Mac was already using and suddenly my Mac would stop working because it was no longer logged into the router at the address it thought it was using). It also makes it much easier to do any networking tasks if you always know where to find a given device on your home network. It doesn't matter which of the two networks I log a device onto, the Negear router assigns it its IP address (the Airport Express is routed through the Netgear router via Ethernet).

Have you tried plugging in your Apple TV via wired Ethernet to see if that behaves any differently than using wireless?

(I have another copy of iTunes running on a Powerbook, and it can't see the ATV either.) Every other networked device in my home network works just fine, including an Airport Express. You plug it in, it should work. Period.

Here you talk about it not recognizing the device, but earlier you said it was working but dropped it. Which is it? To get a computer to recognize an Apple TV, you MUST pair it up with that computer first or it will not work in iTunes period. Just working after plugging it in sounds nice, but that's not how iTunes operates. It needs a pass code first. You must select to pair it up with a computer in the Apple TV menu. At this point, ANY computer running iTunes should then show an AppleTV as a device and will then ask for a pass code that's listed on the Apple TV screen which you must enter into iTunes. It will want to register the unit for the main computer to sync with (additional computers added for shared access will ask for a pass code, but not a register).


Sounds easy enough. But: (1) I think I should be able to buy a consumer product and have it work as advertised, no hacking required; and (2) I've heard the mother ship periodically resets hacked ATVs to the default configuration. If that's still true, hacking doesn't seem worth the hassle.

The current hacked software has an optional BLOCK to prevent Apple from updating your Apple TV automatically. I've used it and it works perfectly. After I unblocked it to upgrade my software this past time, it did remove the hacked menus after the update, but to get them back, I only had to put the USB key into the back and within 2 minutes, it was back to the way it was. Apple didn't remove anything on the hard drive itself for those install preferences (i.e. once XBMC was back up, it still had all my prior preference settings intact) so it was really quite painless to get back up operating. The only thing to make sure of is that the hack works with the latest updates before installing them. The units can always be restored to factory operation if desired, though. I think the hack will even let you backdate your Apple software to previous versions if you don't like an update for some reason.

OTOH, if AppleTV just won't work for you for whatever reason, you might want something like a Popcorn A110 or C200. It will do 1080P as well. The menu system isn't as nice and you don't get things like movie rentals, but it seems you can't have everything these days (yet anyway). The C200 has optional Blu-Ray capability, although I think it just plays discs when a drive is connected.

Personally, I've got all my movies, all my music CDs (even DTS ones), all my photos and all my home videos available with a few button clicks with my Apple TV units. It's SWEET. I can also get on the Internet (Couch Surfer) and even watch old TV shows (Boxee; although Hulu doesn't run very smooth for HD). If the ATV hardware were sufficient to run full 1080P at good data rates, the device would be perfect for my media uses. As it is, I only have a 720P projector at the moment anyway, so I've been simply re-encoding HD movies to 720P for the moment. I can also do a whole house party mode with both my Apple TV and Airport Express units. At the moment, that means having 4 different rooms and stereos playing the same music in perfect synchronization, all of which I can easily control from my iPod Touch anywhere in the house and even from the backyard. I can even see my PC web cameras on the iPod Touch through the Remote Buddy application. If only the iPod Touch had IR outputs to control all my other stereo equipment directly....
 
Open Ports

I have the same problem as everyone else here. Two apple TVs. Used to connect to the desktop now they don't (Itunes on the desktop doesn't even see either one). I can connect from either of my macbooks without any problems. I have tried restarting router, computer, Apple TV, updating software, re-installing Itunes, without or without firewall, removed firewall software, etc. Nothing works. Given that both laptops can connect though, I tried to identify the differences. Although the desktop is a couple of years old, it is running 10.6.1 and Itunes 9.0.1 as are the macbooks. I have home sharing initiated on all of the machines. One difference I did find is that port 3689 is open on the laptops but not the desktop (and I have no idea why). This is (I think) the port used for Apple TV/Itunes file sharing. I am wondering if this is the problem. Anyone have any thoughts? Anyone have any idea how to open the port on the desktop?
 
It's iTunes

Personally, I think the problem is itunes itself. They are constantly updating the app. they are more worried about selling songs, movies, iphone apps, while the world watches the number one music retailer. I feel they are neglecting the appletv code part of itunes, or all these updates are screwing with it and they are not sure how to fix it.

Also not everyone uses the same version of itunes, which may explain why everyone's situation is different.
 
Spoke too soon

Looks like I spoke too soon. iTunes is dropping the AppleTV again. At least once a day.

This is really the only time I've been disappointed in Apple. And I am bitterly disappointed.

As I said, I've used every version of iTunes since iTunes7.x and they have all worked fine except when I was on a bad network connection. I also used them on three different computers (PPC Mac, Intel Mac and XP PC). I still think the problem is a networking one (and yes networking problems can occur over wired connections as well).

Fine. Then it's a networking problem. It is, however, a networking problem SPECIFIC to iTunes/AppleTV, since none of my other devices "lose sight" of each other. It is a networking problem that spontaneously begins, since I had a rock-solid AppleTV connection for over a year before this started, without me changing a thing other than upgrading to Leopard.

Given all that, surely it is Apple's responsibility to figure out, "Hmm, it seems that some networking problem is causing an issue with our gadget. We should look into this." Since the connection can be reestablished as easily as quitting and restarting iTunes, how difficult can it be to add some code to iTunes that says, "Is there an AppleTV on my Devices list? If not, go find it."
