I am having some issues with my Apple TVs dropping out while a teacher is mirroring. I also notice that when streaming video off the web (youtube,vimeo,etc) I have a noticeable stutter. What settings should I be looking at in Hivemanager to improve performance of my Apple TVs.

I am having similar issues. We are running a mix of 10.7, 10.8 and 10.9. Not sure if it the wifi or the apple tv's.

Here are a couple of things I'd try if possible:

1. Hard wire the Apple TV and client for testing purposes (just to isolate a wifi or an Apple issue)

2. Try another Apple TV

3. Make sure Apple TV is up to date and turn Bluetooth off.

I suspect this is due to a bandwidth issue with the higher resolutions such as at 1080i/1080p.
Do you have an AP that is in close enough proximity to the AppleTV to sustain the higher data rates? Is the client also in close enough proximity to get the same? Which model of AP are you using?

Have you also ruled out interference issues or capacity issues from other clients?

I strongly suspect that if you test with the AppleTV plugged in on the wire, you will notice heavily reduced to no issues.

(I would also ensure that you have updated to 6.1r3b if you are running 6.1r3 as, depending on your configuration, this could be causing you pain.)

I am having  similar issue. The Apple TV keeps cutting-off in the middle of presentation. My senior management is very annoyed by this. We were running on Apple Airpod earlier and Aerohive document says that, it can be best on Apple Environment, and now we are doing Aerohive POC in Apple Environment where all devices are fully apple. During this POC, we are facing a lots of issues like, client connection not stable, apple TV cut-off and intermittent connection issue. It just a basic setup with one SSID using WPA2-PSK. Senior management keeps on complaining about the Wireless stability which is not stable using Aerohive AP121.  Is it true Aerohive can work seamlessly on Apple Environment as they claim they do.... Please advise if special setting are required to support apple Environment. I was promoting Aerohive Wireless during the initial stage for this initiatives and now being questioned by everyone in my organization about the stability.....any expert in here... please kindly help or advise....

x2 on the settings question. We are also having issues with Apple TVs cutting-off in the middle of streaming.

We've ruled our interference, added an extra AP121, AH and Apple software are up-to-date, and swapped for a new Apple TV. Wiring to the network isn't an option right now (probably a summer project).

Dave,
I think Nick and Brad are on the right track.  Also may be related to other area's like content filtering and bandwidth contention(Especially with youtube).  But I'd guess it is due to design and contention for airtime especially since you are running the Apple TV wireless as well as the clients.  I've seen these issues with other Wi-Fi gear and it came down to planning.  Please let us know what you find. If you take the Apple TV to an area where you can plug it in to the network and then rerun the test, that may give you more of an indication on whats happening.  What happens when you do this from a wired connection?

Thanks

All the issues that I have seen here have been with airtime contention, interference or an inability of the client or AppleTV to make use of the higher data rates necessary to sustain mirroring. Transient/sporadic interference is a big problem. None of this is anything Aerohive specific. This is why many recommend putting the AppleTV on the wire where you want to support this reliably.

I would also recommend using a three stream 3x3:3 AP, like the AP330, AP370 or AP230, if you want to support this in a busy environment.

The AirPort Extreme has been a 3x3:3 device since late 2009 in its 4th generation.

Kurt and Nick,

I'll try the wired solution, as soon as I can figure out how to get airplay to be on two IP address ranges.  Wireless at our school is 192.168.0.x and wired is .10.x, so as things are configured now, when an AppleTV is wired it is no longer on the list of available devices in Airplay.

I would still love to know if there are any settings to change on the APs (upgrading to 330's, etc.. isn't an option right now).  I know from past experience at another school, certain settings can be tweaked to help with roaming, minimum data rates, etc..   Maybe I'll open a support case.

Do you have band steering to 5 GHz enabled?

Nick, have you seen the band-steering help or hurt?

I just deployed 150 AppleTVs all wired, with different vlans then wireless clients.

the Bonjour Gateway needs the vlan[wired appletv vlan] available as well as the switch trunk ports for BJ ap and every L2 trunk to your core.

if you create a vlan just for AppleTVs, then you can filter the services from Appletv vlan to client vlans.

for BJ election you would have to include the wired appleTV vlan on every AP trunk port or you could change BJ priorities for a few APs and just add the vlan to those trunks.

All,

The problem does not appear to be the apple TV's.  I think it's a symptom.

I did some testing over the weekend, and with no one else in the bulding, only a handful of other clients on the AP (mostly iPads in the cart), and not connected to an Apple TV, streaming video was breaking up/pausing regularly.  I played same videos from YouTube on the wire with absolutely no problem. Same results in several classrooms.   Signal-to-Noise ratio was consistently in the high 20's or low 30's, so I think we can rule out interference.  I disabled 2.4 GHz across all APs and on both SSIDs, but no improvement.  Ping tests to our router showed some big fluctations (3-4 ms, then a jump to 8, 12, 18 ms, then back to 3-4,...).

Unless I'm missing something (always possible), the problem with the access points. I'm calling support this mornig and hopefully they will see something in our config. that will resolve this.

Have you had progress with this issue? We have a similar layout - We have apple TVs on their own VLan and utilizing Bonjour Gateway on our APs. Our APs are a mixture of 330 and 230. The 330s are not having lag issues and the 220s are.

No progress yet, but I also haven't had a chance to wire them.  Since my original post, I've talked to several different folks, who told me hard wiring the Apple TV's are the way to go.  I guess upgrading to 330's is another option.  I would also be curious how 802.11ac might work, but that is at least a year away here at our school.

Was there ever any progress made with this?  We're in an environment where all of the Apple TV's are wired and on the same VLAN as the faculty trying to use them.  Things were fine last year before we switched from our previous wireless vendor to Aerohive but with school back in session now we've had nothing but issues.  I saw the band steering comment and am curious because we're doing band steering.  Any other comments or notes that might help?  We're not using a bonjour gateway as the bluetooth discovery is the direction we chose to go instead of bonjour gateway.  The symptom is just lots of dropouts and lost connections and stuff like that and none of this happened with our previous wireless vendor....

Connecting the Apple TVs via the wire (gb ethernet) helped a lot.  Still not 100%, but works well.  I've told teachers to connect directly whenever possible (VGA cable w/ an adapter to Macbook Air) - not ideal, but it works.  

Connecting on 5GHz band also seems to have helped, but marginally.  We're looking forward to the new AC models. We'll also go with one of the 3x3 stream models, which are supposed to work better in high capacity environments (we currently have AP120's and 121's).

When you have these issues, does it matter how many devices are connected?

I am having the same issues right now as well. Students are on a separate subnet than staff. Staff has brand new Macbook Airs, iPad 4s, and the Apple TVs are a couple years old now. Seems like the dropping is happening more from the Mac than the iPad, but it's hard to distinguish.

We are a  High School  and We are haveing the same issues.  About 60 iMacs  ipad 3s  about 60-100  50-75 Apple TVs Most wireless .  We are using Aeriohives  We have tried several thing but are still having the dropping off of the ATVs.  I am concerned as We Just bought Aeriohives AP130s for our Elementary Schools.

Same problem here with 60 x 230 Aerohive AP's - recently heard a lot of complains about airplay being disconnecting. ALL APs are hard wired. Anything new in this topic?

Fortunately for us, hard wiring the apple TVs resolved the issue (gb ethernet throughout).  Laptops and iPads now connect and stay connected to the Apple TVs.  

FWIW - since updating everything to HiveOS 6.5r3a (Honolulu.2530) a few weeks ago, errors, retries, etc.. seem to be lower (nothing scientific to prove this, just observation via the dashboard).

Hope that helps.

Nothing has worked for us; any movement on success with this?

I've found this to be interesting reading but unfortunately cannot offer any solutions to your quandary. We use a single AP as Bonjour Gateway  at each campus throughout our college group. Apple TV's are connected to the network via cable. We have had issues in the past with multiple devices being elected as BG's which resulted in broadcast storms across the management plane. However this was solved by changing the priority on the AP's themselves to cancel out the election process and disable BG config on all other APs. No problems observed this far.
