Many users seek this file to convert a "Lightweight" AP (which requires a Wireless LAN Controller) into a "Standalone" AP that can work on its own. 1. Preparation

TFTP Server: Download and install a TFTP server like Tftpd64 on your PC.

Static IP: Set your PC's Ethernet adapter to a static IP (e.g., 10.0.0.2, subnet 255.255.255.0).

Rename File: For the easiest recovery method, rename your downloaded file to ap3g2-k9w7-tar.default. 2. Installation via MODE Button

This method is the "failsafe" way to force a new image onto the AP: Power off the Access Point. Connect the AP’s Ethernet port directly to your PC. Hold the MODE button while plugging in the power.

Keep holding until the LED turns solid Red (usually 20–30 seconds), then release.

The AP will automatically look for the file ap3g2-k9w7-tar.default at the IP 10.0.0.2 on your TFTP server. 3. Installation via CLI

If you already have console access and the AP is booted, use the following command:

archive download-sw /force-reload /overwrite tftp:///ap3g2-k9w7-tar.153-3.jf15.tar Use code with caution. Copied to clipboard Troubleshooting Tips Note: Some older WLC versions do not support

Windows Firewall: Disable your firewall or allow UDP Port 69 for the TFTP transfer to work.

HTTP Server: In newer Autonomous versions, the web GUI is often disabled by default. You may need to run ip http server in the CLI to access the browser interface.
