1522 Firmware failure

Unanswered Question
Jun 1st, 2008

Hey, has anyone else experienced this after upgrading the firmware on the Wireless controller? I loaded AIR-WLC4400-K9-4-1-190-5-MESH onto the controller to follow the upgrade path and after it pushed the newer firmware to the AP it no longer boots correctly, the status lights say firmware error, but the image does load without grabbing an IP address and LWAPP association. I am about to attempt a recovery using the files from another AP.

I have this problem too.

download the code once again from the Cisco web and use that to upgarde the controller. Also power cycle the controller once and try the upgarde the process. I personally ran into a similar issue on a WLC2006 controller and after the power cycle

the upgrade process went through fine.
