Re: 1121G AP unable to register to 4402 WLC

Hi Sundar,

The only time I have seen this problem (refuse image download) is when the WLC is running an older 3x image. The support for the 1121 AP was added in 4.0.155.0, so if you are using a 3x image on the WLC you will recieve this error. You will need to upgrade the WLC image.

The 1310 and 1121 AP support were added to the list of AP's that can be converted from Autonomous to LWAPP. This change is supported on WLC 4404 running 4.0.155.0 (and later)and on AP's that have been upgraded to IOS 12.3(11)JA first.

From this doc;

Hope this helps!

Hi Rob

Thanks for the response, the current image on the WLC is 3.0 and FYi the APs are LWAPP and not the autonomous one converted, let me try to upgrade the image and check out the response, will keep you posted..

Sundar.
