Re: ERROR:- Cannot upload the config of WLC.

Hi Neha,

You need to reboot the WLC controller if the WLC is placed on the WISM Module you need to reload the WISM module after that you will be able to upload and upgrade the firmware on the controller.

This is happening due to some internal isue with the WISM/WLC hardware. I request you to do this and your problem will be solved.

Try leaving the tftp path blank instead of "/"

Check your TFTP server for errors, just in case the filename or directory are wrong. If the TFTP server has no errors, there's probably something wrong with the information entered.

I can't think of any other settings off-hand. Have you tried it from the GUI yet? Maybe try that to see if there's something you're missing from the console configuration.
