9.8 and iPad issue

  • Updated 3 years ago
We have a customer running 20x R700 and therefore running firmware 9.8 on the ZD.

Generally it is working great except for iPads. They can connect to the network and work but after 5mins connections is lost. The iPad still shows as connected but there is no internet, airplay or anything network related.

If we disable and re-enable wifi then it works again for another 15ish minutes.

SSID is visible, WPA2/AES.

Can anyone suggest what is happening?

There can be many things that can go wrong and not all are related to WLAN. I'm using 9.8 and my iPad is working just fine.

Does your ipad still have an IP at the time you can't access the internet any more?

Hello Andrew,

When this happens "after 5mins connections is lost. The iPad still shows as connected".... what does event's and activities on ZD shows?

as far as i know usually such issues are seen after channel change which could be triggered channel fly or background scanning etc.

Questions:

What is IOS version on the iPad you got?
When "The iPad still shows as connected but there is no internet" happens. Are you able to see other SSID's on the iPad?

IPads are on latest (7.1.1). This is about 30 iPads not just one.

Worked fine on 9.7.1 with ZF7372. ChannelFly has been enabled, whereas previously it was just set to background scanning.

I'll check the ZD logs

Hi Andrew,

Please open a support case. 9.8 is just about to "freeze" for the GA release and if this is a new bug we'd like to identify it in time to resolve.

That said, it does look similar to an issue already corrected in the 9.8 GA. If these are first/second generation iPads, it's probably the same issue. Setting encryption to WPA would also be a valid test.

They are iPad 2's I believe but am confirming. When is GA going to be released?
Will changing to WPA fix it for now?

From reading the bug report WPA should act as workaround. 9.8GA is just a few weeks away.

They are iPad 2s. I will try a temporary WPA for iPads only and see if it works.

Thanks

I have the exact situation with 90 iPad 2s, ZD 9.6.2.0. build 13.

I've taken one of these home and the connection is fine on my wireless at home. I've noticed it seems to lose the connection after going to sleep.

Did you make any headway using WPA? Other ideas?

Thanks

@Slym - that's likely a different issue. The one I mentioned is 9.8 specific

@Keith - I realize the OP was talking about 9.8. But the symptoms, for lack of a better term, seem exactly the same.

I've already seen that link, and they're talking about a guest SSID with the captive portal. Maybe it's the same issue, but it seems the train of thought there is the reauthentication on the portal is causing the problem. We're not using a captive portal for these iPads.

Changing to WPA has appeared to partly sort the issue. Internet and network activity no longer drops.

Still have an issue with AirPlay giving up after a few minutes. We are going to try an iPad mini tomorrow to see if that sorts the problem.
