Mobile devices loose Internet connectivity but not network connectivity on ZD1200

When mobile devices are connected to a ZD1200 controller with Zone Flex 7982 AP's, I have a situation where some connected mobile devices loose internet connectivity. Connectivity to the AP is not lost and local resources can still be accessed.

The typical sign is the distinctive exclamation mark that appears over the wireless connection indicator on Windows and Android devices.

I have seen this at one of my other running an unleashed network. 

Has anyone experienced a similar situation?

Strange behavior Anton. What version ZD firmware, and do you have other wireless clients (PCs, other phone types) which do not lose Internet access?

ZD1200 supports 7982s on our latest firmware.  Both 9.13.3.0.133 (MR3 Refresh4) and 10.0.1.0.35 (MR1 Refresh) have just been posted with WPA2
KRACK patches in them, if you can schedule a backup and upgrade to your ZDs for further testing?

sounds like a DNS issue to me...
on a windows laptop on WiFI, are you able to ping anything on the internet at the time of problem?

I am not sure if Windows or mac based nachines connected to the wireless loose connectivity and I have not checked because I have not had complaints. It seems to be restricted to phones or Android and IOS devices. 

My laptop is connected to the wired network and I don't have a problem when my phone has the connectivity issue. For some odd reason I have never tried to disconnect from the LAN on my laptop and check when it happens...I will definitely check the next time it happens but as luck would have it everything is work fine at the moment.


The ZD firmware is 9.12.0.0 build 336

I have now got the situation where my phone and my laptop are connected. My phone can scan the local network and ping local devices but not access the internet. My Laptop can access the internet and the local network. Interesting though once I ran the ip scanner the internet access returned.

Something to note is that it tends to happen if I was offsite and return to the office.

More info. If I stop & start the wifi on my phone it does not solve the problem. If I re-boot my phone the problem is resolved.

Is there a firmware update for your phone OS?

The latest updates have already been installed.

I'm checking who of the people that complained about the same problem have it at the same time as I do, maybe I can get to the bottom of this.

Thanks,

I have the same issue with one ZD1200 on the latest firmware, and a mix of r710, r700 and r7372... iOS devices indicate a strong WiFi signal but it takes them 3-4 minutes to mysteriously regain their internet connection... without the iOS device having changed location I might add ...
