Converting Cisco AirAP3802i to Mobility Express Mode

Most online guides will tell you to use ap-type mobility-express to convert a Cisco AirAP3802i (or similar APs) into Mobility Express (ME) mode. This command has never worked for me - not on this AP, not on any of the other AirAPs I've tried. Even after flashing ME firmware, the option simply doesn't appear in the CLI.

After lots of trial and error, I've found the only reliable method: reflashing directly with the ME firmware via TFTP.

The Command That Works

1archive download-sw /reload tftp://192.168.50.124/AIR-AP3800-K9-ME-8-10-196-0.tar

This loads the Mobility Express firmware directly and triggers a reload. Once the AP reboots, it'll come up in ME mode.

Finding the Firmware

This is where it gets tricky. Cisco's firmware downloads require a valid support contract... mostly.

Tip: An older version (8.3.x I believe) is available for free download. You need to register a Cisco account, but you don't need a valid support plan for the older firmware releases. If you have a current contract, you can download the latest (8.10.196.0 as shown above).

First Boot Behavior

When the AP first comes up in Mobility Express mode:

1. LED is green - The AP boots and initializes
2. LED turns blue - When you connect the first device to the provisioning SSID, the LED changes from green to blue

The Provisioning SSID

On first boot, the AP broadcasts a default SSID called CiscoAirProvision with the password password. Connect to this SSID to access the initial configuration wizard.

Initial Configuration

Once you've connected to the CiscoAirProvision SSID:

1. The AP LED will turn blue (indicating a client is connected)
2. You can access the web UI or CLI to complete the initial setup wizard
3. If there are no other controllers on the network, the setup wizard will start automatically

Both the web UI and CLI offer similar configuration options. If you have a console cable, the CLI is often quicker for initial setup.

Summary

The key takeaway: skip the ap-type mobility-express command entirely. Go straight to the TFTP flash and save yourself hours of frustration.
