Dear All,

This AP model is supported by controller version newer than 8.2.102.2!

Hi Rasika,

Hi Rasika,

Simplest way is to:1. Access

Simplest way is to:

1. Access the AP via console and delete all the contents of the flash EXCEPT for the primary LWAPP image the one with the "rcvk" meaning, you should only have one file on the AP

2. Configure its original IP address
#capwap ap ip address <IP> <MASK>
#capwap ap ip default-gateway <GATEWAY>
#capwap ap controller ip <WLC-IP ADD>


3. Re-join it on the WLC :)

If is still doesn't join, download a higher version of the LWAPP image of that AP and upgrade it
Once upgraded, try to rejoin i

Re: Simplest way is to:1. Access

Hello!  thanks for this, for some reason our japanese ap's were not querying the dns name cisco-capwap-controller.  I hard coded the controller name and IP using "capwap ap primary-base <ap dns name> <IP address of controller>" and restarting capwap discovery.

 

just in case anyone needs it.  thanks!
