As we can see the 15.3(3)JA1 is compatible with controller firmware release 8.0.110.0 – both released in 2014. My access point out-of-box had preinstalled firmware 15.3(3)JA1, the latest vWLC version 8.6.101.0 requires the 15.3(3)JG1. The FailureCode:3 does not point to a reason. The access point joined the controller successfully and attempted to download the current archive from the controller, but the whole operation failed.

What are the symptoms that you cannot upgrade your access point automatically? On the web dashboard, you will see the access point reappearing with Operational Status set to Downloading. My lightweight access point image is too old Sometimes you need to perform a manual lightweight access point firmware upgrade procedure which is not well documented. Is it working? Yes, usually, but not always.

The idea is that access point upgrades its firmware when it registers to WLC. It has been on the market for years, evolved from LWAPP to CAPWAP model, is supporting a wide range of access point models. The Cisco lightweight access point managed by the wireless controller is not a new product.
