Why does my iOS5 iPad 2 lag / lagging while in mirroring mode?

Yes, I am having some of the same issues!! See my post for help https://discussions.apple.com/thread/3380258?answerId=16362979022#16362979022

Same exact problem here!

Same problem here:

a. When I click on the camera the sound comes 5 seconds after wards

b. On the keyboard on some characters it takes ages to get a response

c. On infinityBlade no audio

Information has been only slowly creeping in about real world experiences with iPad 2 mirroring on the official IOS 5 so there's not a ton to go on with this problem and I can't find a link that explains how mirroring even works (technically that is, not how to enable it). I have an iPad 2 on iOS 5 and 2 current gen ATV's on the latest 4.4 OS, 1 in an upstairs bedroom and 1 in the downstairs living room in my home (where the Internet connection ingresses). The downstairs setup works pretty much as you've seen in all the sneak peek previews over the last year, in other words quite well and impressively. However the upstairs setup is 100% unusable due to absurd amounts of latency, frame rate and audio dropout. Even just browsing around in the OS is unusable, never mind playing games or runnng other apps. Interestingly, if I take the upstairs ATV and swap it into the downstairs setup, works just fine so I know it's not the ATV itself. This polar opposite performance really has me scratching my head.

Things I've tried for process of elimination:

-factory reset and restore of the ATV

-turn off all other electronics in the room

-swap the hdmi cable

-move the iPad and ATV around the room (as much as possible anyway)

None of this made any discernible difference which leaves me with only one conclusion as to what the problem could be: the WiFi (I'm using pure g). There's no question that the signal strength getting to my upstairs is weaker (usually a bar less on iPhone or iPad) but the ATV itself reports 5 of 5 bars so I don't really know what gives here plus streaming from Netflix works perfectly. It's a real shame I can only use mirroring in 1 room of the house after investing in 2 ATV's so I'm hoping more information will be forthcoming as people troubleshoot this further.

Update: by taking my issue to the extreme and literally standing out in the hall with my iPad (where the WiFi signal is a tad stronger) I can just about eliminate the above problem with mirroring. So it seems to me the unfortunate situation for those of you with a single ATV and massive mirroring lag is either you rearrange your setup so there's less obstruction between the ATV, iPad and WiFi gateway (walls and so forth)...or get a ridculously powerful WiFi gateway....or both. Perhaps in time Apple can tweak things to be a little more forgiving. Anyone with this issue seen drastic success moving to a pure n setup?

I most definitely agree Beers and I'd bet over time Apple will get it working better in less than optimal setup's so people like me can have ATV's around the house. I'm willing to be patient for now but mainly only because I have a 2nd setup that does work well. =)

Yes precisely, I've no way hardwire my ATV to my Internet connection but no doubt that would solve everything (just as using the AV adapter for mirroring instead of an ATV would). It's interesting though that you optimized the 'ATV to WiFi leg' of the connection and saw great improvement while I was optimizing the 'iPad to Wifi' leg (as I really had no other choice anyway). I guess the take home message is the same though, mirroring is incredibly sensitive to less than optimal WiFi networks. Even with decent signal strength and lots of bandwidth (I get 13-15 Mb speed tests in my upstairs) if there's a lot of distance and obstacles (walls, etc) it can really play havoc with mirroring.

I'm having lag / freezes issues with a linksys wifi N router, connected via wifi (wirh router, apple tv and iPad all in the same room and very close) and with the ethernet cable. It's very noticeable primarly when playing mirrored games like asphalt 6, where it lags a lot and drops lots of frames, so it's unplayable.

I do not believe it is the wifi. My setup is: Main house has cable modem with built in wifi and 6 port lan. One those lan ports is a run to the guest house and connected to a 24 port cisco switch and from the switch I have port 2 going to linksys wireless router. My 3 Tivo's, AV Reciever, Apple TV, TV, Set Top Box, Xbox 360, PS3 and my Nas server all are connected to the switch. So when you are in the back yard or my guest room you can get wifi from the linksys (running in gateway mode).

So sitting in my room 8 feet from the linksys router and mirroring to the apple tv ethernet connected I had very bad lag. When I play Dungeon Hunter on the Ipad 2 it will randomly drop video or audio and other times it will lag 30 sec behind what is on the ipad 2 and what you see on the TV. I think moving your stuff around you are getting the perception it is less laggy.
