My IAP 305s are running with firmware 6.5.1.0-4.3.1.0_57768. The latest version available is 6.5.2.0. I tried to upgrade the firmware manually but got the error "Invalid Image File".
Then I tried "Automatic" and it said there is "-- No new version available --".
Next I tried the debug-download command and was able to successfully connected to the image server but the images are not available(I tried two version).
The firmware filename is ArubaInstant_Vela_6.5.2.0_59123
