i m trying to upgrade 1252 AP from standalone to LWAPP mode using cisco upgrade tool v3.4.
i have configured all things correctly but getting error "Unable to Load the LWAPP Recovery Image on to the AP"
i have referred upgrade troubleshooting document.
i have downloaded and used the following images from cisco.
You see this error during the upgrade:
FAILED - Unable to Load the LWAPP Recovery Image on to the AP
When you see this error, complete these steps:
Verify that your TFTP server is properly configured.
If you use the Upgrade Tool embedded TFTP server, a common culprit is personal firewall software, which blocks the incoming TFTP.
Check if you are using the correct image for the upgrade.
The upgrade to lightweight mode requires a special image and does not work with the normal upgrade images.
plz help me out
thanks in advance
