The existing firmware may be too old and not have the correct certificates to check for updates.
The easiest way to get out is to get factory images for the version you want to deploy
-HERE- and after that, the firmware update check should work again.
If you have an active support contract on all of the APs, you also can select a specific firmware version from ASP (Aruba Support Portal).
