Wireless Access

We are a school with about 100 AP135s and 7210 controllers. We've rolled out about 40 AppleTVs in classrooms just for Airplay mirroring. Overall, things are working fine, however we are now seeing intermittent, significant time lag (minutes) between actions on the computer, like mouse movement, and the AppleTV display. We have not been able to reproduce the problem at will.

Clients are a mix of Mac Book Pros and Windows 7/8 computers. No iOS devices are using Airplay. All AppleTVs are wired, all clients are wireless.

Has anyone else run into this situation? I've openned a TAC case, but wanted to reach out to the community as well. Please note - this is all about performance, not connections - we are not seeing connections dropping, or at least are not hearing about that as a problem

My current guess is that ARM changes are confusing the airplay connection - not enough to drop the connection, but enough to drop packets and confuse Airplay.

Thank you,

Tim Palmer

sorry, not something i recognize, but please do report back what your ticket with TAC turns up.

We are seeing the same issues..

Here is our setup

1. 7210 controller along with IAPs (134/135)
2. All Apple TVs are wireless
3. All Apple TVs are displayed via a projector
4. All clients are wireless (iPads, Macbook Air)

Testing Done

1. Replaced Apple TV with a new one out of the box
2. Updated the code on a few Apple TVs to the latest ver
3. Replaced IAP
4. Adjusted the resolution and refresh rate on projectors

Issues we still see

1. Youtube videos lag
2. just simple mouse movements lag
3. Video from DVD players lag

Note:

1. We are also unable to reproduce at will
2. We now currently have approx 1700 Apple TVs deployed and this issue is now a major thorn in our side
3. The IAPs seem to be chill'n at CPU <10% and Mem Free >145m
4. We are also opening a TAC case about this issue

Qwazy,

Do you have "Drop Broadcast and Multicast" on all of your Virtual APs?

That setting is set to "ALL"

Timmo - 

Were you ever able to resolve your issue?  We've recently opened a TAC case with the same thing.

Thanks!
