on ZD3000 (9.6.2.0 build 13), upgrading firmware of ZF7762 AP is not working.

check below logs

That is odd. Wanna try against a ZD I have here? See if that will give the same results? I have a spare zd1012 that is reachable from internet. It will have a different FW than yours, so that might trigger the upgrade.

I think this likes to happen if an AP doesn't have an IP address. Can you check if it does or doesn't have it and that it's not the default if it does.

I did the upgrade manually but the AP is still in Provisioning state.

The problem was MTU miss-match between ZD and AP.
