unable to upgrade cisco wireless lan controller 4402 firmware

hi,

I am in the midst of trying to update the controller firmware of a cisco wireless lan contoller 4402, and having some issues getting the file to transfer to the controller.  i am currently running verison 5.0.148 on the controller and attempting to upgrade to the latest version of 7.0.230  and for whatever reason it continues to not transfer. I have tried all 3 methods of cli, gui and using wcs software. all the no avail , I have tried tftp32 and 3cdaemon with the same results.

The error that i am getting from 3cdaemon is got socket timeout aborting code 10054, failing at 66MB transfered. I increased the timeouts both on the wlc and  the tftp client to no avail

the error i get on the wlc is Code file transfer failed - Error while writing output file

any help with this process would be greatly appreciated.

Try to upgrade to the next highest code from what you currently are using to see if that takes.

Could mean a few things ...

1.  What is your bootstrap version?  (sh sysinfo)  This happens when you are upgrading the firmware but did not upgrade the bootstrap first.

2.  Firmware you have downloaded could be corrupt or not "complete".

3.  Firewall.
