Slow Apple TV

Hi!
My Apple TV is suddenly really slow.
Every thing worked fine up until a month ago or so.
When I try to airplay a movie, (from iPhone, iPad, iMac) it takes for ever to load. And when I mirror my iMac through airplay to my tv, it lags big time.
Also, just updated it (today) to the latest update, but it still lags.
If anyone knows what causes it, please let me know.
Thanks in advance.

Hey vazandrew,
Thanks for the quick responce!
So, i tried istumbler, and I'm not sure what I'm looking at (I'm not too much of a techy). istumbler only works when my iMac's wifi is turned on, but I have the iMac hooked up to the Airport extreme with a ethernet cable, so I don't use wifi on the iMac.
But when i did turn the wifi on it showed my main network and guest network twice (2 of one and 2 of the other), I think its showing the main network running on 2.4GHz and 5GHz and the guest network running on 2.4GHz and 5GHz since it has the dual-band 2.4GHz and 5GHz (but i think you knew that already) (and the letters got big and i don't know how to change it back :$).
now the figures that istumber showed, i'm not sure what to make of them.
here is a print screen of what it shows.
[file://localhost/Users/martinvendrame/Desktop/Screen%20Shot%202013-09-26%20at%2 04.58.02%20PM.pdf]
turns out i cant get a pic here (would it help if you saw a print screen of it?)
Also, i googled the probelm (which is not always the most reliable source) and found a bunch of people with that problem but no solution yet. I'm thinking its the Apple TV but I'm not an expert.
I hope this is more details that will help you.
Thanks again for your help!

Fix for slow Apple TV sync or stream (port 3689 alert)

If you use Intego VirusBarrier X6, syncing or streaming to your Apple TV may be extremely slow or stop altogether. Your network connection may also be broken. The same may also be true with other virus protection or internet security software.
In many cases, you may receive an alert message saying: Check that any firewall software running on this computer has been set to allow communication on port 3689.
Here is how to modify your VirusBarrier Firewall to open port 3689. If you use other security products, you will need to check with the vendor for specific instructions.
1) In VirusBarrier X6, go to the Firewall section and set the Mode to Advanced.
2) Click the "+ icon" at the bottom left of the window. This will add a new "untitled settings" entry to the list on the left of the window.
3) Right click or control-click in the rules window (the blue and white striped area of the window). Choose "Insert Standard Set" and select whatever setting you were using before (for example: Client Only, Client Local Server, which is the default setting). This will insert the standard rules for that set.
4) Now you must create a new rule for the Apple TV. Click the + button (bottom left). The new rule window will appear.
-- You can name it anything you like, but something that tells you what the rule is for would be recommended. For example: Apple TV.
-- Set the source as "Local Network", the destination should already by "My Mac".
-- The 'Service' option is where you assign what service this rule applies to. However, there will not be an Apple TV option in the list. You must create a new service. Click the '+ sign' next to the services drop down menu. A "new service" window will appear. Name the service something appropriate for it's function (for example: Open port 3689), set the Protocol to TCP, click Single Port, and enter 3689 for the Port.
-- Leave the Interface set to Any, and make sure Allow is enabled.
-- Allow should be enabled, then click OK.
5) This new service you just created will now be at the bottom of the Rules list of your new "untitled settings". You MUST drag it to the top of the list (making it rule number 01).
6) Click the button next to your new "untitled settings" to activate them. Apple TV should now be able to sync (or stream) without problem.

I am having the same problem since upgrading to ATV 2.3 and iTunes 8.0.2.20 for a PC. Since people are having this issue with Mac iTunes, my guess is that it is ATV 2.x that's the problem. Everything stopped syncing as far as I could tell. Apple Support was totally unhelpful. Wanted me to pay for extended care even since I bought my ATV last year. Told me it was "buyer beware" with respect to updates, and that my only recourse was to role back to the factory default (version 1.1) - that is unless I wanted to pay for support. So I asked her if she'd heard of the problem, and she said no. Excuse me? What would I be paying for then? Why can't this company support the piece of junk software they just released??? They are shooting themselves in the foot because now that I've rolled back to 1.1, I can't buy the new content they're pushing from the iTunes store. I've never been this put off by a company and the false advertising that "it just works."

Another slow Apple TV thread

I know this has been raised before but im largely out of ideas.
I have an ATV (3rd gen) - it's up-to-date software wise. I am using the ATV plugged into the net via ethernet.
I have a 100mb connection (photo attached) - DNS servers are set to my isp's preferred settings...
I have reset/restored...without any difference.
Key question.
Why the **** is it so SLOW to download tv shows? Seriously, it takes 15-20 minutes to buffer at times. While at other times it downloads and buffers within 30 seconds. Is there something wrong with Apple servers?
In the words of an ex-girlfriend, "It's not me - it's you".
Please fix.

Hi, thanks for replying.
In relation to your questions:
diesel vdub wrote:
Is the slowness specific to iTunes downloads? Netflix? YouTube? or all streaming content?
Has the ATV been reset or restarted?
Has the router been power cycled?
Has the ethernet cable been replaced?
Has a different port on the router been tried?
1) Just itunes downloads. Others (we don't have Netflix in Aus...well, leagally anyway) work fine.
2) Yes - see above email
3) Yes - but im not sure what the point of that would be given the ATV isnt working on the router as it's through an ethernet cable.
4) Yes and tested - hence the speed test to show the slowness isn't from the cable but from the connection to itunes servers.
5) No, Ill give that a shot but im not optimistic.

Good wireless in house, slow Apple TV in downloads and syncing. ATV issue?

OK - I just did a internet Ping test and bandwidth test and have found that my overall bandwidth is good, but my ATV is still very slow on downloads and syncing.
My bandwidth is over 6.6mbps and ping rates are nearly 45ms.
Here is my issue - I often have no images show up on ATV when I am browsing the movies. I also have to restart for lack of response to the remote about every other day, sometimes every day.
Am I looking at my wireless in the house (running Time Capsule) or is this an ATV issue? I have good overall connectivity and internet downloads via iTunes, etc.
Your insight is appreciated.

You may or may not already have your network set up correctly, it's just that I can't tell from what you have said.
I have a main router provided by my ISP, I have several other Airport Extremes and Airport expresses connected by Ethernet, all set up to bridge the network created by the main router.
Each maker has their own settings, but bridging should be reasonably obvious. In simple terms my main router distributes IP addresses to all devices, the Airports bridge that network by passing these addresses to the devices from the main router. A base station that isn't in bridging mode will distribute its own addresses to the devices connected to it.
I don't really follow your next point.
instruction for configuration vary from manufacturer to manufacturer, the best course of action here is to refer to the manual. If everything is set up properly the addresses of everything on your network will have identical sets of numbers for the first 3 of 4 groups of numbers that make up an address, the last set must always be different. I think the part you are referring to with your DD-WRT is the option to have Ethernet and wifi bridged or not.
Some routers may be easier to configure than others, but generally speaking they should all work with the Apple TV. 5Ghz is less likely to suffer interference but it is much more likely to be blocked by solid objects, it may or may not be an advantage.

Sluggish / slow Apple TV menus

I had this annoyance before upgrading to 3.0 I think, but I can't help feeling it's now worse.
Essentially, menus are just sluggish and slow to respond to clicks on the Apple Remote. Sometimes clicks will register instantly, but more often than not the unit takes a second or so to respond to my button presses. The LED registers clicks so it rules out a problem with the remote. It's just like using a computer in which the CPU is maxed out.
Anyone else suffering from this?

Thanks for the good suggestions. I'm running in 720p, so I don't think that'll be the issue. I wonder if it's a network problem, so I'll try disconnecting it in the morning.
One thing of note is that almost all my media used through Apple TV is streamed over 802.11n from a Mac elsewhere in the house. The signal strength is decent, but do you think the sluggishness could be caused by so much of the data coming across the wireless network?

Slow apple tv download

Seriously 57 hours to download a movie on apple tv ??? Have 15 Mbps service, which is about as fast as it gets without a T1 line...
Ok - very unlikely to do this a second time.

The Apple TV itself is the bottleneck. The problem is not bandwidth.
My home theatre system uses Apple TV for most content. I also use a MacMini for the few DVDs I have and for EyeTV television recording.
Same as all the posts to this thread - performance slowed badly the last few months.
However, I notice that if I download rentals and purchased movies through iTunes on the MacMini, it works as the Apple TV did before. That is, start the download and wait a minute or so and then watch the movie end to end without interruption.
Also, iTunes allows me to cache the full movie if I give myself a few minutes prior to the time I want to watch something.
Not great. But it works.

Extremely slow Apple TV sync

I have begun to sync my iTunes to my Apple TV. Everything has gone as planned except that seems to take about 10 minutes per song- literally - to sync. At 2000 songs this will take a long time. Is this normal??
tks

Welcome to the  Discussion Forums.
No it's not normal, but since your songs clearly are syncing and the sync is not simply hanging, I'd suspect your network. Are you connected by wifi, could you be experiencing interference or perhaps you have a weak signal. Have a look in the network menu on the tv to check your signal strength,

Linksys Router Slowing Apple TV Downloads, but Nothing Else

So here is my problem.
I have very fast cable modem broadband (16/2). But Apple TV HD content seems to download at less than 1Mbps.
My system is cable modem (Scientific Atlanta) to Linksys WRT54G (broadcasting on channel 6; no significant strong nearby WiFi signals) wirelessly to Apple TV / Powerbook G4 /iMac (with WPA security).
If I run download tests of 100MB files, I'm clocking over 10Mbps most times, clocking about 6-8 Mbps during primetime hours. Yet no matter what time of day, Apple TV HD downloads clock in at about 1Mbps.
At first I thought Comcast was to blame (see previous thread). But I've ruled this out by connecting the modem directly to the Apple TV via ethernet, and then getting extremely fast downloads. I've also connected the Apple TV via ethernet to the router, and achieved extremely fast downloads.
So the problem appears to be in how my router communicates with the Apple TV. I've read in these forums that changing the "multicast rate" on an Apple router improved Apple TV performance, but there is no such setting on the Linksys. The only thing that comes close are the settings for "basic rate" and "transmission rate" neither of which make a difference. There is another option to disable the "filter multicast" function, but as far as I know Apple TV is not multicasting in the way that say an IPTV service like BBC's does.
So I'm at a loss. For now, I'm just leaving the router plugged into the Apple TV via ethernet, but I'd rather (for other reasons) go in wirelessly.

Linksys, eh???
In the router's setting, try disabling "IPS" if your particular model has that feature.
When I upgraded my service to 30/5, I was still getting only 10/4 BEHIND the Linksys router (but 30/4 direct from the modem). So somehow my Linksys RVS4000 was restricting, or not processing quick enough. Disabling the IPS function solved my problem. (But since Linksys uses IPS as a security feature in a proprietary manner, and I don't like to be unprotected, I've since gone with a D-Link router that's safer and faster...)

Very Slow Apple TV download

I am finding that anything I try to download takes a very long time on my apple TV ?
I have checked my internet download speed and it is around 13.6 which is good.

Hi and thanks for tyring to help. I mentioe DNS because it was mentioned as one of the things to check in a trouble shooting guide that needed to be identical - our T.V. and ISP DNS setting are identical. I should of mentioned that we are using wireless from a modem provided by our ISP Shaw Cable. I changed our interne channel on Shaw cable client portal from channel 1 to 11, also tried 6 - to no avail. Our signal strength on settings and about is 4 bars out of 5 - so very good. Today it is actually stuck on 56 minutes to download the same movie as we tried yesterday. I think this problem is definitely on the Apple side of things. Any other ideas? Our modem is in the basement and we just do not have an ethernet cable long enough to try that way.
Out of luck out of ideas - Owning 5 other Apple devices this is the first time they really dissapoint me....

Slow Apple TV 2

Slow Apple software updates

Hi everyone
I've got a really strange issue with Apple software updates. I'm with TalkTalk in the UK and for the past 2 weeks, software updates are silly. As in kb/s and something like 7MB taking 5 mins or so. Currently, speedtest shows download of 73.27 Mbp/s and upload of 16.78 Mbp/s. Clean install of Yosemite and currently shows 23 hours to update to 10.10.2. If i download this update direct from Apple as a .dmg, it's around 5 mins.
Everything else runs like lightning, and it's not just this machine. I repair quite a few and upgrade yet get this on every one when doing updates for anything. 10.6 to 10.10. Spoke to TalkTalk and might as well have been chatting to the dog. Wondering whether it's something like TalkTalk changing which Apple server they now direct me to as this has never been an issue until 2 weeks ago.
Have rebooted everything, etc. This is on clean installs and on current updates. Very odd and hoping someone may be able to point me in the right direction.
Any ideas?
Many thanks.

Sorry but tried that, and pretty much everything. Found a page discussing bypassing proxy settings for apple servers, changed DNS, still the same.
I've currently got my iMac (10.8.5), a Mac Mini (10.10) and a MacBook Pro (10.10.1), all exactly the same issue. Even little files such as RAW updates are taking 10 mins. Any third party updates i may have via the app store as as normal and super fast, just actual Apple updates.
Can't see it's a system setting as across 3 machines on different OS's so it would have to be router or provider issues i would think. The router seems fine as nothing untoward on there and literally everything else is fine. Browsing and downloads from elsewhere all normal.
Very odd one...

Slow Apple ID support

Is anyone else not getting Apple support emails thru at the mo'??

I would suspect that iTunes support is very very busy answering questions relating to iOS 5 update, iPhone 4S and regulare problems.

Stopping downloads due to slow Apple servers

Prepurchased album 1-2 wks ago. For some reason, 1 song from album was available then and I downloaded it. Album for sale yesterday so I logged in and completed the purchase. iTunes knew I had purchased 1 song so I was told to "Complete" the sale. I did so and then NOTHING. No downloading. I checked again and followed through a 2nd time. Again NOTHING. A few minutes later, I find I am downloading 2 albums. Is there anyway to stop or cancel a download before it completes? So much for the "Special" deal from iTunes. Would have been cheaper to buy at Wal-Mart!!! And of course, we all know how easy it is to contact Apple!!!

Once an item enters the download queue, the user cannot remove it. Either let it complete the download (easiest) or contact the iTunes Store customer support department through the form linked from the bottom of their Download FAQ web page and ask them if they'll remove the item from your queue for you. If you've been charged twice for the same purchase, then you must contact iTunes Store customer service.
Regards.

DNS issues, iCloud and Internet Accounts on OSX System Preferences, Apple Web Services and Sites Slow/Unresponsive

Hardware/Software:
Macbook Air Mid 2013 1.3Ghz 8GB RAM 120GB SSD / Mac OS X Yosemite 10.10.1
Issue:
Occasionally, Safari, App Store, iTunes, and any third party app that connects to the internet using Safari's rendering engine in my case was SafeinCloud - all fail to connect to the internet. Changing the DNS solves the issue but happens again after that, thus you would constantly have to change the DNS. Apple.com, iCloud.com, Apple Forums (this site) would also all be slow to load and access.
Troubleshoot:
Changing DNS works for OSX, however for the slow Apple websites not so much.

Hello mogwai_100,
It may help to reinstall Mac OS X on your system. The directions in the article linked below are for Mavericks (OS X 10.9), but will work for OS X 10.7 and OS X 10.8 as well.

Updated Safari to Version 6.1 now it doesn't work at all

What gives?
I installed the update from the abysmally slow Apple App Store application, you know, the one that you click to open and it sits there thinking for about enough time to go fill a kettle, put it on to boil, fix a cup of tea or coffee, drink it, and then it's loaded up a screen of options that messes up your computer worse than it was yesterday. Can anybody tell me what I need to do to hold Apple's hand and walk my computer through to functioning? I feel like I have a crappy windows OS installed on a sub-par desktop...
OSX Mountain Lion 10.8.5
Mac Mini 2.5 GHz i5
The whole reason I switched to Mac is because I always had to do stupid stuff like this with Windows computers, constantly fidgeting and fixing problems. I went to mac because things just worked. You didn't have to worry about one thing not being compatible, it just all fit together seamlessly, it was simple, it worked. Ever since Steve Jobs passed away, everything that made Mac great is now just ordinary. Where is the innovation? What happened to the seamless design? Will Mac ever be what it once was? Good design....
For goodness sakes. I have to use google chrome right now...

hi i need your help, im having problem also with 3gs, ive updated from 5.1.1 to 6.0 but itunes ask me to restore which i did, but now my iphone stuck in the configuration like asking for language, country etc. i cant even activated it and also it says no service. in itunes it says no sim card to activate the update.PLEASE HELP ME
