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?

Hello,

Greetings!

Did you try to SSH into the impacted APs when the controller was on 10.5.1.0.279?

Any specific reason you upgraded from 10.5.1.0.276 to 10.5.1.0.279?

Please share the info requested.

"Any specific reason you upgraded from 10.5.1.0.276 to 10.5.1.0.279?"

Maybe because you just announced a critical security vulnerability giving unauthenticated users root shell access on earlier versions?

I have not tried any type of SSH connection because unfortunately I am not prepared for this type of diagnostics and I did not have time: in the departments they were demanding Wi-Fi!

Once connected in SSH what should I check? with which commands?

Thanks
