User recieves the error message TFTP Failure while storing in flash during a Wireless LAN Controller (WLC) upgrade

Core Issue

This error message appears if there is a problem with the Trivial File Transfer Protocol (TFTP) server. Some TFTP servers have a limitation on the size of the files that can be transferred.


Try to use a different TFTP server utility. There are many free TFTP server utilities that are available. Cisco recommends use of the Tftpd32 version 2.0 TFTP server. Refer to Tftpd32 in order to download this TFTP server.

For more information on upgrading and troubleshooting, refer to the Troubleshoot section of WLC Software Upgrade.
