Clients won't reconnect after AP Firmware Upgrade...

Currently we are running AP Firmware 5.1.2.0.373 in our Default Zone, where 4 Zones are included and it works quite fine.

When upgrading to a newer Firmware, last tried with 5.2.1.0.698  - three zones are working as usual, but in one zone clients wont reconnect to the wifi networks anymore, except a few. Mainly we use R500 APs. When downgrading to the old AP Firmware, everything is fine again.

Maybe anyone has an idea, or a hint why this is happening?

Hi,

Could you please explain more about the client behavior?
Are the client unable to connect to the wifi or it is connecting but unable to reconnect when it goes to sleep mode?
Is this happening for any specific client models?

i have no problems with guest portal, after trying some things and investigating, i found out that all published Wifi Networks are shown as open after the AP Upgrade. 



when doing a downgrade back to 5.1.2.0.373 the networks are switching back to secured!

Hi,

Is this shown the same way on all the clients? Even on the clients which are working?
Can you take a working client and try to place it on the non working client location (so that it can connect to the same AP) and see if you can reproduce the issue?

its on one of our remote site, hence i cannot test so much.

windows 10 laptops e.g. all will disconnect and the wifi-networks are shown as open.
there are some echo dots which dont care they still cann connect, also a few samsung galaxy devices (not all). iOS devices wont connect either.

from 20 devices, only 6 devices will reconnect after the update, mainly with android os. did a downgrade again all is working fine.

but it is just this one site. the other sites are getting the update too, and the devices all work as expected. also tried to create a new AP-Zone but this didnt help either.

Hi there,

Could you run the troubleshoot utility from the controller GUI and share the screenshot of client connection?

I think you may need to open a case with support, as this is not something we can fix without in-depth troubleshooting like AP log, controller logs, AP packet captures, etc.
