AP's won't connect to controller

Hello,

I'm new to the Cisco Wireless products. We acquired a Cisco 2504 wireless controller and a couple of Cisco Aironet 1602i AP's.

I was abled to configure the controller, but the AP's won't join.

This is what the AP's spit at me when I connect to the console:

*Mar 1 00:01:43.606: %CAPWAP-3-ERRORLOG: Discovery response from MWAR 'Cisco_Wi

Fi_Controller'running version 7.0.220.0 is rejected.

*Mar 1 00:01:43.606: %CAPWAP-3-ERRORLOG: Failed to decode discovery response.

e from controller

The version of the software of the AP's is 15.2. The controller has software version 7.0.220.0.

What is causing these messages?

Thanks,

Wim

1600 AP require 7.4.x.x WLC software. So upgrade your 2504 & try this.

Updating the controller to version 7.4.100.0 resolved the problem. The AP's have all connected to the controller.

Thanks for you help!
