A console cable connected to the AP and a network cable connecting the AP and PC (directly or via a switch). Ap3g2-k9w7-tar.153-3.jbb1.tar WORK
This technical guide outlines the architecture of this specific firmware and explains how to successfully complete a lightweight-to-autonomous conversion. Understanding the Firmware String
:
If your autonomous AP is working and you have CLI or console access, you can use the archive download-sw command. You must first host the .tar file on a TFTP, FTP, or HTTP server accessible from the AP. | Component | Meaning | Explanation | |
Note: Formatting the flash is optional, but highly recommended to ensure you have enough memory to untar the new image and prevent lingering configuration file conflicts.
Set your PC’s IP to 10.0.0.2 . The AP will automatically look for the server at 10.0.0.1 . Hold and Power: Unplug power from the AP. Hold down the MODE button. Plug the power back in while continuing to hold the button.
The file is typically loaded via a TFTP server during a ROMMON recovery or by using the archive download-sw CLI command. For recovery purposes, the file is often renamed to ap3g2-k9w7-tar.default on the TFTP server to be automatically pulled by the AP.

Use this method if the access point boots up and lets you log into the Cisco EXEC/Privileged command prompt via console.
You can convert a lightweight Cisco AP using two primary methods, depending on whether you have command-line access or require a hardware-based reset. Method 1: The Standard Command-Line Flash (CLI)
Before configuring the hardware, acquire a physical console cable, an Ethernet cable, a dedicated desktop TFTP server utility, and the standalone image file.
