Choppy video playback with Airplay Mirroring

I am experiencing virtually the same phenomenon. My AppleTV 3 and my Airport Express are 2.5 feet from each other. My iMac is across the room (about 17 feet) on a direct line of sight to the Airport Express. Nonetheless I get choppy playback when AirPlay mirroring from the iMac. Oddly enough, I can use AirPlay on my iPhone with NO choppiness at all. Prior to applying the 10.9.1 update I had better performance, so I'm very much beginning to think the problem lies in Mavericks. Something is slowing down the signal from the iMac back to the Airport Express..

I'd welcome any thoughts about this.

Thanks.

I have a cnetury link router connected to an airport express. I have found where to turn off WMM (century router), but it says I can't since I am in N mode. Can someone let me know what "N Mode" is?

Thanks!

FIx choppy video playback apple tv from macbook air mid 2011

For Linksys router:

1) Open your web browser.

2) In the Address Box at the top of the browser window, type http://192.168.1.1 and then click on Go, or press the Enter key on the keyboard. A window should appear in the center of the screen asking for your User Name and Password.

3) Leave the User Name box blank. Type admin in the Password box, then click on OK, or press the Enter key on the keyboard.

4) The Linksys Wireless Router Setup page should appear.

5) Click Applications and Gaming Tab

6) Click QoS

7) For WMM Select disabled

8) save

I have an Apple Time Capsule and cannot find the WMM setting. Any other ideas? I am getting the same choppy play back from my iMac and Macbook Air to my apple tv and its 2 feet from each other.

Please help!!!!!

Hi, I have the same problem as you.

I bought a brand new Mac 21,5inch late 2013 2,7Ghz i5 8Gb ram Intel Iris Pro 1536. I did a fresh install of the Yosemite. I have and Apple TV 3, all updated. I had this problem with an old modem Linksys E1200 I thought it was due to speed and interference from other wifi signals so I bought a brand new Asus RT N56U due it has a lot of good revisions. I configured all my devices to work under 5Ghz, there is absolutely no one else in 5Ghz so the signal is completely clean. I check and the Qos is disabled, there is no other connection. I restart all my devices.

But still the problem continues. I also check the configuration of the HDMI output due before I had some improvements when I forced to RGB high or RGB low, however in this case is not working at all, I have the same problems.

Mi router is 5 mts away from mi apple tv and the mac and the signal is 4 of 5 in my apple tv and 5 of 5 on the mac. I have no other process running and still does not work properly.

I tried to use beamer to see movies I have on my hard drive however this is only a partial solution. Due I cant see Hulu or any other service that runs on normal Airplay.

Same as other I use airplay with Iphone 4, 4S, 5 and Ipad 2 and works perfect no chopping in any device, just from mac.

Im a new user on Mac and I'm very disappointed with this problems, I hope someone can help.

fixed my issue, I did have to disable the service on both frequencies.

DIsabling WMM resolved the issue for me too. THANKS for the fix!

It was found on my router through; "Media Prioritization" - "Settings" - "WMM Support On/Off".

Same problem.

Mid 2011 iMac > ethernet connected to Cisco Valet M300 router > Wireless to ATV

Before it was very VERY choppy. Like unwatchable choppy. Frames would literally freeze for a second, like watching satellite TV in bad weather. I disabled WMM in QOS settings and it immediately made a world of difference but still nowhere acceptable to watch. My wife thinks I'm being picky but it is still noticeable by me and 4 other friends. As others have pointed out streaming services like Netflix work fine on ATV. I have yet to run direct ethernet from router to ATV, which may be my only hope, but it doesn't solve the underlying issue. Obviously there is some kind of bug in ATV that needs to be worked out or simply the device cannot handle mirroring HD video wirelessly which makes it about as useful as a nicely shaped doorstop. If I have to run an ethernet cable I might as well have saved $100 and ran an HDMI cable direct from my computer to TV.

Again, I really don't think there is a solution as simple as disabling WMM. At this point I'm just letting Apple know they need to go back to the drawing board.

I have had Apple TV for over 2 years now and have been using the AirPlay feature beautifully with iPad and iPhone. I recently purchased a couple of MacBooks and an iMac. I am now experiencing all of the problems you all are as well, but only with my computers. My iPad and iPhone still work with no trouble at all. I get the choppy, unwatchable picture when I attempt to mirror with my MacBook pro. My ATV is plugged into my router by ethernet cable and I use AirPlay over wireless. It is apparent to me that the problem is in the computer software and not with the routers, cables or signals. I think Apple needs to evaluate where the differences are in the computer software and the iOS software and make the appropriate corrections. I had hopes of using a similar set up to use when I teach or make presentations.

I have a TP LINK AC1750 Archer C7. I was having laggy video issues and I did solve it.

First, both Apple TV and my Macbook air 2014 (4GB RAM, the basic model) where connected to a 5G network. When I was airplay mirroring a video, I always had choopy/laggy video.

If I connected the Apple TV in the ethernet cable, no lag anymore.

What I did to resolve wifi laggy issues?

I connected the Apple TV to the 2.4G network, and Macbook to the 5G network. Problem fixed. 🙂

I switched off the bluetooth on MBP 13 retina and it works all great
