Chapter 4 Troubleshooting 1240AG Series Lightweight Access Points

Returning the Lightweight Access Point to Autonomous Mode

You can return a lightweight access point to autonomous mode by loading a Cisco IOS release that
supports autonomous mode (such as Cisco IOS Release 12.3(7)JA or earlier). If the access point is
associated to a controller, you can use the controller to load the Cisco IOS release (refer to your
controller documentation). If the access point is not associated to a controller, you can load the Cisco
IOS release using TFTP.

Using a Controller to Return the Access Point to Autonomous Mode

Follow these steps to return a lightweight access point to autonomous mode using a controller:
Step 1 Log into the CLI on the controller to which the access point is associated and enter this command:
config ap tftp-downgrade tftp-server-ip-address filename access-point-name
Step 2 Wait until the access point reboots, as indicated by all LEDs turning green followed by the Status LED
blinking green.
After the access point reboots, reconfigure it using the access point GUI or the CLI.
