You have to get "debug client

You have to get "debug client <MAC-Address>" output from your WLC when client connection failing. That will give you a reason code for authentication failure.

Pls attach that client debug output to see

What type of Authentication

What type of Authentication are you using?

Do you use radius/tacacs for authentication?

What type of controller are you bouncing the AP between and what are the two code versions?

What color are the lights flashing?

hi aflanders6276

it is open authentication

no radius or tacacs

the two controllers are WISM2 with version 7.4.121

the AP flashing with only green color and the SSID is broadcasting from it.

thanks in advance

hi Manannalage ras...,

I already issue this command and tried to connect on the SSID but there is no output appeared on the controller it seem to be that the client MAC address is not reach to the controller

note that,

the AP connected through Modem to the controller and get the controller IP address from DNS by resolving its domain name to the controller IP

Hi Rasika,

If we have AAA (radius server) in place for client authentication, will debig client <MAC> give the output or we have to debug aaa <all/events/packets>
