I have a cisco wireless controller 4402 with 1020 LWAPP access points install. I did an upgrade of the software to today. I got and error and reset the sytem. Forgetting that the access points may have been updating their software. Now i cannot detect any access points. Is there anyway to get the access point to communicate with the controller again?

Hi Adrian,

The 1000 series lightweight access points are not supported with the 5.2.x software image.In fact 1000 series APs are not supported from 5.0.148 onwards.


Now, you need to check on the controller.If the current software version is then it will obviously not detect 1000 series APs.If the image on the WLC is something prior to let me know so that we can try some other steps.
