In the above output, you can see that there is no AP Image Type and AP Configuration , so we can further proceed to convert AP to Mobility Express.

Step 6:  Verify now that AP can reach the TFTP server and upload the latest downloaded version.

After image is downloaded, it writes to flash and reboots.

Step 7: After reboots, AP broadcasts CiscoAirProvision SSID. You can start configuration Mobility Express by following our article – Configure Cisco 1850 Series Mobility Express AP.

In Step 4, if you see AP Image Type is Mobility Express Image and AP Configuration is Not Mobility Express Capable, then you need to just change AP configuration to Mobility Express Capable.

AP reboots and comes up as AP Configuration Mobility Express Cable.
