I have a ZD1100 running 9.6.1.0 build 15. it controls 8 APs all zf7962. The firmware has been upgraded to the latest for a while now. This morning however 4 of the APs seem to have reverted back to a 9.3 version of the firmware and now are updating their firmware over and over again (i assume trying to get back to 9.6 version) effectively bringing down the wireless network for half the office.
Anyone know why this would happen and what ic an do to prevent the APs from upgrading their firmware on their own even though they are controlled by the ZD and i never ok'ed an upgrade?
