Upgrade from firmware version 7.1.91.0 to a latest stable one

[Prince K Mathew]

Hello,

We are running WLC 5508 with software version 7.1.91.0. We have recently run into bug CSCua29504 which prevents Windows 8 devices from joining the SSID which is configured with WPA/WPA2 with AES. Can someone suggest me a latest stable version to which i can upgrade our system.

Thanking you in advance.

Bootloader Version............................... 1.0.1

This means the WLC has never had the FUS upgrade.  Upgrade first to 1.7.0.0 using CLI (instructions already posted) and then reload the WLC.  Only after the bootloader has been successfully upgraded to 1.7.0.0 can you upgrade to 1.9.0.0 and this time you can use the GUI.

What would be my current FUS version number? I just need this information so as to get the data from vendor.

[Leo Laohoo]

The current version of your bootload is the (factory) default version.
