Although streaming via regular AirPlay (not using mirroring) from my iPad to Apple TV works perfectly, when I use mirroring, the video and audio can appear jerky, and there is a noticeable lag. What can I do to resolve this?
iPad 2, iOS 5.1
Mirroring by its very nature cannot buffer like basic AirPlay does because it needs to reflect what is on your iPad screen, therefore it depends on a better network than basic AirPlay. Your network is not good enough and needs improving. Your problem might be signal strength due to distance or you might be suffering from interference.
Hi. I moved the iPad closer to the Apple TV. This has improved reception quality somewhat, but it's still jerky, and sometimes it totally kicks me out of mirror mode. Are there any more modifications you can recommend so that I can improve the network and have a smooth reception on the TV?
Have you checked for interference.
Intermittent problems are often a result of interference. Interference can be caused by other networks in the neighbourhood or from household electrical items.
You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
Refer to your router manual for instructions on changing your wifi channel or adjusting your multicast rate.
There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first.
hi, nice to meet you all.i seem to have a similar problem.
i am using a macbook pro late 2011, 2.2Gh, 4Gb RAM to stream internet videos directly to a 3rd gen apple tv. i have close to 30mpbs download speed and 5mbps upload speed. however, i found that there is too much lag, making the whole experience quite unbearable.
do you think this problem is caused by ℹ low upload speed (does my computer upload the movie to the apple tv?) i found that the video plays just fine in my mabook pro and it seems to download faster than the actual play time for the movie...; (ii) low RAM (although i really dont think that is it, the computer seems fast enough for other more complicated tasks; (iii) something else
It's being transferred via your local network. I would check interference as suggested as well as distance between device and router.
Hi marujera, your internet speed does not determine lag, the lag is caused by something in networking called "latency". Since your screen has to be streamed to the Apple TV in real time, there will be a little lag to deliver the display to your TV in a timely manner.
In an effort to minimize this using airplay mirroring, connect an ethernet cable directly from your macbook to your router and another ethernet cable from your Apple TV to your router, latency is a huge disadvantage when using wi-fi, which also makes wi-fi a poor choice for online games and the like.
I fixed it by upgrading my router. My old one was a few years old. AirPlay works fine now.
What router were you using? And what did you upgrade to? I'm using a dualband Netgear WNDR3400 - N600. Think a router upgrade would fix the video choppiness with my Airplay mirroring?
Why is there a lag, image jerky?
