Working on a WiNG install using all 7632i access points (about 10) with one of the APs running as the virtual controller (VC). All has been well when updating the firmware over the past year until earlier last week when we tried 5.9.2.3. We upgraded the AP acting as the VC and the update was successful (from 5.9.2.2 to 5.9.2.3), but when we try to push the update firmware update to the other APs, it's not sticking.
What is happening is the AP downloads the firmware without issue, sets the next boot to secondary and restarts. The AP comes back up with 5.9.2.3 loaded, connect and all looks good for about 3-5 minutes. Then the AP suddenly reboots, fails back to the secondary 5.9.2.2 image and runs on the older code. When consoled into the AP we see no error at all, only a message stating that the AP is rebooting.
We tried updating to 5.9.3.2 and still the same issue. The VC AP takes the update just fine but the other APs keep failing back to the older 5.9.2.2 firmware. This is also the case with upgrading from the command line as well as the webUI.
Thoughts?
