Apple TV 3G AirPlay Mirroring Stuttering

I have alreadys posted in other threads but there is no thread with my exact issure.


In particular I have problems with the AIrPlay Mirroring with games on the new Apple TV 3G and the iPad 2.


I have tried 3 different Routers: one with 150 MBit/s, one with 450 MBit/s and one dualband 300 MBit/s.


The issue remains the same:


1. AirPlay Mirroring is not 1080p on my TV. Tried 2 TVs, an LCD Samsung B650 and a new Plasma Panasonic STW50. On both TVs there is a visilbe 5cm black frame around the picture. I looked at the Apple TV settings and looked at the zoom and overscan settings on my TVs - so I couldn't find any errors in sthe setings.

2. AirPlay Mirroring stutters on the TV that bad that it is not playable! I tried all variants 50Hz and 60Hz and no change. Music videos from my iMac didn't stutter once!

3. From time to time the whole Mirroring freezes fo a second and the continues (and I'm out of the track and naturally out of the race)


I tried 3 games: RealRycing 2, Asphalt 5 and Modern Combat 3 - all the same issue.


So what the heck is happening here!?!


WiFi network isn't to slow or to far away (same room 3m ftom couch and 0,5m to Apple TV, wired connection to the router didn't help either).

+ Either the new Apple TV 3G or the iPad 2 seems not to support WMM, which can be switched on on some routers; the opposite happens: disabling WMM makes AirPlay work between iPad 2 and Apple TV3. With enabled WMM I wasn't even able to play music!


It seems like the Apple TV is buffering too slow or that the hardware is to weak!

(There is one thread where Apple TV buffers videos and stutters the same way. I didn't try look some long films, only Music Clips.)

Mirroring isn't supposed to use 1080p on the Apple TV 3.


Mirroring works fine for me on both the Apple TV 3 and the Apple TV 2, if you are having problems, the problem will likely be with your network. Mirroring places a greater demand on your network since it needs to work in real-time unlike basic airplay which can buffer the stream before play starts.

I believe the problem you are experiencing might be a result of more than one factor:


1. What is the source of your High-Speed Internet service: DSL, Cable, Satellite?

2. If its DSL, how fast is the DSL speed?

3. Does your computer Network contain only one LAN device and is it "N" rated?


Your router is pulling 3 way duty simultenous for this one task:

1. one for the game

2. sending the game to the Apple TV wifi

3. then 3 passing it along


How many other network devices do you have going in your home/building?

DSL speed doesn't matter! It's only Mirroring! 🙂


My WiFi Router is the new Linksys E3200 (dual band 300 MBit/s). Should be enough.

As I already said: In my network during the test there was only my Apple TV 3G, my iPad 2 and my iPhone 4 in stand-by mode.


One thing to mention: The E3200 supports WMM to speed up streaming but actually it stopps all kind of streaming between my iPad and my Apple TV.

When I want to connect my iPad 3 to the WiFi in N mode, WMM should be enabled otherwise my iPad 2 doesn't conect at all 😟


Solution there: Switch off the WMM and so I'm not able to use the N Netwotk.

Is that content you are playing Cloud based?

My gut is telling me there's a latency issue and its related to a slower DSL speed.

Even as I think this through it doesnt make sense that slow DSL speed would affect this matter however, somewhat, I believe its the issue.


Do you have DSL? And how fast is it?


I want to test this both against slow DSL versus Cable Internet to see if we can duplicate your problem
