We encountered an issue with one of our Cisco 1850 Access Point, it was not joining Mobility Express Controller and throwing an error while you click on that specific AP on Mobility Express GUI under Wireless Settings.
However show ap join stats summary all command tells that all APs have successfully joined the controller.

“show ap image all” command shows that I got different AP image and probably this could be causing trouble in interoperability.

On further troubleshooting, I connected to this problematic AP via console and found out that it was running CAPWAP and no AP Image Type and Configuration are displayed in “show version” command. Read more information about Mobility Express here.

After upgrading this AP from CAPWAP to Mobility Express version, our issue got resolved. Read more information about converting CAPWAP to Mobility Express here.
