AP no longer connect to ZD1200 after firmware upgrade from 10.5.1.0.276 to 10.5.1.0.279

[GLFI69]

Hello, after the firmware upgrade and ZD1200 rebooted, i saw some APs show firmware upgrade and some disconected like a normal upgrade process.

but after 20 minutes the situation did not evolve and all the APs remained disconnected.

I tried to restart an AP manually but it didn't help.

I have three types of APs but they are all supported by the latest firmware update.

I had no choice but to revert to the previous firmware version and all APs reconnected without making any configuration changes in fact I was able to ping all APs from the controller even though they were not connecting.

I have a support license valid until June 2025.

Has anyone encountered the same problem?

Same Problem here !!

265 > 279  > None of our 38AP ist found !!  

University Campus WLAN is offline

Bad idea to update !

We definitely had version 10.5.1.265 installed - but it doesn't seem to exist???

Unfortunately, we no longer have the image and it can't be found in the download area.

We're now trying to go back from version 279 to 276.

Thank you !

Finally I have already found .265 (MR6) in the downloand area and after downgrade to 265 everything works fine ... 
Recently:

279  > NO APs found
(Downgrade  to) 276 > Still No APs  found
(Downgrade  to) 265 >  Cluster (2x ZD1200) works as before. 

Actually we are using 38 APs  (R600, R710) and two ZD1200  but all of these devices are have now reached EOL  ..  know we now why ...
