Upgrade WLC 4402 problems

Answered Question
Jan 21st, 2008

Hellow

I've got a problem with the upgrade procedure for a Cisco 4402 WLAN controller. I want to install new firmware on the controller, but the TFTP upload is not successfull.

The new image is 37 MB. I've got a TFTP server that supports these large files. I've got threee WLC's and the problem is the same on every controller:

After a few bytes, the controller stops the download.. "Image not complete". Upgrade not successfull.

What is the problem ? Via CLI the same problem.

Hi Remco,

Can you confirm which code your controller is running currently and which code you are trying to upgrade?

Also can you try upgrading using tftp server which is tftpd32.

First make sure you have the right rev of code. Second, make sure you have stepped through the right code versions to get to where you are going. IE. the 4.2 code requires you to be at least at 4.1 I believe. I may be wrong on that one. If you have met these pre-req's my bet is you have a corrupted file.

Problem solved:

Upgrade process starten via the Service interface. Not via the network. Image uploaden by tftpd32 and everything is ok now !
