Upgrading Cisco LWAPP to Autonomous IOS (1140)

Upgrading Cisco LWAPP to Autonomous IOS (1140)

This tutorial will walk through the process of converting a Cisco LAP (Lightweight Access Point) to run the full autonomous IOS. The full autonomous IOS allows for an AP to be configured manually and removes the requirement of having to have a WLC (Wireless LAN Controller) on the network. This tutorial covers the process used to convert an AIR-LAP1142N-A-K9; the same process can be used for other 1140s under different regulatory domains as well as other models. It is recommended that a deployment with 5 or more APs should utilize a WLC to allow for simplistic deployments and troubleshooting procedures. Read through the whole process before attempting the upgrade process. If you are uncomfortable with what is required to perform the upgrade do not attempt. *UPGRADE AT YOUR OWN RISK* This tutorial was written using Version 15.2(4)JB5.


      • Cisco LAP capable of running a full autonomous IOS (1142)
      • Full autonomous IOS for specific AP (c1140-k9w7-tar.152-4.JB5.tar)
      • TFTP server software (tftpd32)
      • Ethernet cable(s)
      • Console cable
        • USB Serial Converter (if required to console)
        • Terminal Emulator software (Putty)
      • Power source for AP


  1. Connect all cables (Console, Ethernet, Power[if using power brick]) into AP
  2. Wait for the AP to boot
  3. Once the AP is booted, login to it via console
    1. Username: Cisco
    2. Password: Cisco
    3. Enable: Cisco
  4. Run the following “hidden” command: debug capwap console cli
  5. Configure the AP’s interface with an address that’s on the same subnet as your TFTP server
  6. Verify your TFTP server can ping the AP’s IP address
  7. Begin the download process of the new image from the TFTP server:
    archive download-sw /force-reload /overwrite tftp://<tftp ip address>/<image name.tar>
  8. Allow image to download and be extracted
  9. After the extraction finishes, the AP will reboot with the full autonomous IOS
  10. At this point the AP can be configured via CLI or GUI(Once setup to work) as a normal AP

Command Summary:
debug capwap console cli
configure terminal
interface bvi1
ip address
archive download-sw /force-reload /overwrite tftp://
