Apple TV Drop Outs

Hi all,

We've been having issues with Apple TVs on and off for a while now. It seemed to have all been resolved, until a recent reboot of the controller which may have lost some of the configuration.

The problem is that when AirPlay mirroring, iPads will randomly disconnect mid session. After being disconnected, the user will no longer be "see" that Apple TV in the list, until they have put the iPad in Airplane mode, then back again.
Unfortunately, it doesn't seem to be only certain Apple TVs/only certain locations. Its very random and difficult to troubleshoot. 

We have a 7210, running Aruba OS 6.3.1.1. We are no longer using AirGroup due to it causing problems with printing.

Any ideas/suggestions would be much appreciated!

Thanks,

Stephen

Re: Apple TV Drop Outs

Did you have this issue when AirGroup was enabled? It is not recommended to use AirGroup-type services without AirGroup enabled because of broadcast and multicast in the air.

Yes we did unfortunately. I would prefer to keep AirGroup enabled but the printers just dont work at all with it on.

Re: Apple TV Drop Outs

What kind of printers? Are you trying to use AirPrint or DLNA printers?

 

AOS 6.4 is required for non-AirPrint printer discovery (Windows, Android, Linux)

Re: Apple TV Drop Outs

A variety - we use a system called PaperCut which utilises virtual printers, set up with generic drivers. Had the same problem with a couple of Dells and HP that weren't going through PaperCut as well. All shared through our Apple Server, so using AirPrint.
The printers would just disappear from the air after a short while, which would require "re sharing" them from the server. There was a support case open about it, but as disabling AirGroup "fixed" it, the case was closed.

Re: Apple TV Drop Outs

Are you able to sniff the PaperCut server to see what service advertisements it is sending out (SSDP)? Sometimes you need to add a custom service ID to AirGroup (AOS 6.4).

Hi Stephen

We experienced a similar issue with a school we were dealing with. It turned out there was a recall on some models of Apple TVs check the model number for an extended warranty Programme with your local Apple Service provider.

Re: Apple TV Drop Outs

It just advertises the printers using the standard AirPrint services. We looked at it with Aruba's engineers but they kept trying to blame our print server - and seeing as all those issues went away as soon as AirGroup was disabled that was obviously not the case.

Re: Apple TV Drop Outs

Hi Stephen. The Programme is for 3rd gen appletvs with last four letters in the serial no. Being DHRN. Ensure they are running 5.2.1 and if still dropping or unable to join the network consult your local AASP.
Hope this fixes your issue.
