I have a 2504 controller and I am trying to add a 1200 series AP .

The controller has version 7.2.120 version and the AP was just converted from autonomous to lwapp by tftpd32.

Here is what the AP is showing when it is booting up and fails to join.

Here is a previous Cisco community thread that may help:

Did you use the Cisco Aironet to LWAPP conversion tool.

if Yes.

Check the directory where the upgrade tool is installed and see if it created a file (.csv) that contains the SSC for the AP. Then manually add that into the WLC under Security and then AP policies link.

please can you explaine to
