🏢 Authorized Source: You must obtain it directly from the Cisco Software Central portal.
🔐 Entitlement: Cisco strictly locks these downloads. Your Cisco Connection Online (CCO) account must have an active service contract (such as SMARTnet) attached to it to allow downloading.
⚠️ Warning: Avoid downloading this file from third-party file-sharing sites, torrents, or public Google Drives. Unofficial network images pose massive security risks, including malware or pre-configured backdoors. ⚙️ Deployment & Installation Methods
Because the software is distributed as a .tar archive, the Access Point cannot execute it directly. It must be extracted onto the device's flash storage using one of the following methods:
Method 1: The Web GUI or Standard CLI (When AP is already operational)
If the AP is currently running an older Autonomous image, use the standard archive command via the console to pull the image from a local TFTP server:
archive tar /x tftp:// Use code with caution. Copied to clipboard
Method 2: The "Mode Button" TFTP Recovery (For Lightweight conversion or dead APs)
This is the standard recovery and conversion fallback procedure:
Prepare a TFTP Server on a laptop with a static IP (e.g., 10.0.0.2).
Rename the file in your TFTP directory to the exact default name required by the hardware bootloader (usually ap3g2-k9w7-tar.default). Connect the AP's Ethernet port directly to the PC.
Hold down the MODE button on the physical AP and plug in the power.
Keep holding (usually 10 to 15 seconds) until the AP's LED turns amber or red, then release.
The AP will automatically assign itself a temporary IP (typically 10.0.0.1), grab the file from your TFTP server, extract it, and boot into Autonomous mode.
