Converting a Mobility Express AP into a CAPWAP AP

I was recently installing some Cisco 2802 APs and came across an issue where one of the APs  would grab a DHCP address, be reachable for a minute, and then drop off the network.

It turns out the AP having an issue actually had the Mobility Express image installed and needed to be converted to CAPWAP, even though we purchased the APs specifically with the CAPWAP SKU. Here are the troubleshooting steps I went through to convert the AP to CAPWAP.

After rebooting the AP a number of times to see if it would work, I threw a console cable on the device and saw some interesting output.

I rebooted the device again and came to this screen indicating that it was indeed in Mobility Express mode.

To reset the AP into CAPWAP mode you’ll need to enter enable mode on the CLI and enter the “ap-type capwap” command.

The AP then rebooted, got its DHCP address, and successfully connected to the controller.

Documentation from Cisco to convert an AP from Mobility Express to CAPWAP can be found here:

  1. One potential issue with this procedure is that, unlike with correctly delivered CAPWAP APs, a web interface is available after being converted from mobility express to CAPWAP.

    The web interface (port 80) says OfficeExtend and is accessible with default user/password admin/admin which is not possible to see if you SSH to the AP or in the WLC or in Prime.

    This of course open up a security whole and there are several tasks that could be done which you don’t want everyone to have access to.

    At the time of writing this post I don’t know how to get rid of the web interface but perhaps by deleting relevant stuff from flash.
