unable to upgrade cisco wireless lan controller 4402 firmware
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.

upgrading to an intermediate version worked i upgraded to version 5.2.178, not sure why the release notes for version 7 indicated that i could directly upgrade to version 7 from 5.0.148. thanks for all your help
