I am converting autonomous AP's to LWAPP. I have a 4404 controller (WLC). With a AP on the same subnet I can convert and the AP shows up in the WLC. On AP's on different subnets when I run the upgrade tool it continues to give the error "Unable to Load the LWAPP Recovery Image onto the AP". I have tried converting using both the Upgrade Tool TFTP feature and using a external TFTP server. Has anyone had this issue?
