Updating or converting an access point to this autonomous image typically involves using a TFTP server or the device's physical reset button. 1. Standard CLI Upgrade
If the AP is already in autonomous mode, you can upgrade via the privileged EXEC mode:
archive download-sw /overwrite /reload tftp:// Use code with caution. Copied to clipboard
This command downloads the image, verifies the checksum, overwrites the existing flash contents, and reboots the device. 2. Recovery via Mode Button
If the AP is "bricked" or running a lightweight image you wish to convert, use the physical Mode button recovery method: Set your computer's IP to 10.0.0.2 and run a TFTP server.
Rename the image to ap3g1-k9w7-tar.default in the TFTP root directory. Hold the Mode button while plugging in the AP's power.
Release the button after the LED turns red (roughly 20-30 seconds). The AP will automatically fetch and install the image from your server. Strategic Use Cases Ap3g1-k9w7-tar.153-3.jf15.tar Download -
