ap3g1-k9w7-tar.153-3.JF15.tar is a specific Autonomous IOS software image designed for Cisco Aironet 3500 Series Access Points (specifically 3500e/3500i). It converts lightweight (LAP) access points into standalone autonomous mode, enabling them to operate without a Wireless LAN Controller (WLC). Key Aspects of ap3g1-k9w7-tar.153-3.JF15.tar
15.3(3)JF15 - This is a later/finalized version for the 3500 series, highly recommended for stability on older gear.
Autonomous ("k9w7") - Allows the AP to run as a standalone device, providing a "fat" AP configuration via web GUI or CLI. Compatibility:
Designed for AIR-CAP3502I, AIR-CAP3502E, and similar 3500 series devices. Functionality:
Often used for home labs, small setups, or site survey mode, as 3500 series APs are End-of-Sale (EoS) and End-of-Life (EoL). Cisco Community Known Issues & Considerations 404 Not Found in Web GUI:
Users frequently report that after flashing 15.3(3)JF15, clicking "Apply" in the web GUI causes a "404 Not Found" error. This is a known bug in this version. Firmware Access:
Because this device is EoL, finding the software often requires a Cisco Support Contract , leading users to seek alternative sources. Alternative Firmware:
If "k9w7" (Autonomous) is not needed, "k9w8" (Lightweight) is used for controller-based operation. Cisco Community Installation Method (Mode Button)
Setup a TFTP server (e.g., Tftpd32) on a PC with a static IP (e.g., 10.0.0.2). ap3g1-k9w7-tar.153-3.JF15.tar ap3g1-k9w7-tar.default Connect PC to AP via Ethernet.
Hold the MODE button, power on the AP, and wait until the light turns red (approx. 20–30 seconds). Cisco Community
Aironet 3502i WAPs need switched to standalone - Cisco Community
This specific file, ap3g1-k9w7-tar.153-3.JF15.tar, is a Cisco Autonomous AP IOS software image. It is designed for Cisco Aironet 1140, 1260, and 3500 series access points. Quick File Details Filename: ap3g1-k9w7-tar.153-3.JF15.tar Version: 15.3(3)JF15 Release Date: ~2019-2020
Format: .tar (Contains the image file plus the HTML management interface files)
Capability: K9W7 (Autonomous Mode—operates without a Wireless LAN Controller) Why Use This Specific Version? Ap3g1-k9w7-tar.153-3.jf15.tar Download -
The JF15 release is often sought after because it is one of the final maintenance releases for these legacy access points. It addresses security vulnerabilities and provides stability for older hardware that has reached its End-of-Life (EoL) status. How to Install (Manual Upgrade)
To move from Lightweight mode (WLC-based) to Autonomous mode, or to simply upgrade your existing Autonomous AP, follow these steps via the Command Line Interface (CLI):
Prepare a TFTP Server: Host the file on a local TFTP server (like Tftpd64). Access the AP: Connect via console cable or SSH.
Run the Archive Command: Use the following command to extract and install the image:
archive download-sw /overwrite /reload tftp://[Your_TFTP_IP]/ap3g1-k9w7-tar.153-3.JF15.tar Use code with caution. Copied to clipboard
Verify: Once the AP reboots, check the version with show version. Where to Download
For security and reliability, you should always source Cisco software directly from the Cisco Software Central portal.
Note: You will likely need a valid Cisco Service Contract (SmartNet) associated with your Cisco Account to download the .tar archive legally.
Security Tip: Avoid downloading Cisco firmware from third-party "mirror" sites, as these files can be modified with malicious code or backdoors. Always verify the MD5 or SHA512 checksum against the official Cisco values before flashing.

As the 3500 series is end-of-life, the software is generally archived. You can attempt to download it from the Cisco Software Download
page, though it usually requires a valid service contract (Smartnet). Cisco Community : Users on the Cisco Community ap3g1-k9w7-tar
have noted that the 3500 series might no longer be visible in the standard search; you may need to look for newer AP models (like the 3600 or 2700) to find compatible legacy downloads or contact support. Cisco Community Deployment Write-Up To install or convert your AP using this file, follow these standard procedures: 1. Method: CLI (via TFTP/FTP) If the AP is already running and you have console access: Set up a TFTP server (like ) on your PC and place the file in the root directory.
Connect to the AP via console and enter privileged EXEC mode:
archive download-sw /overwrite /reload tftp://
The AP will extract the image, update the flash, and reboot automatically. Cisco Community 2. Method: Mode Button Recovery
Use this if the AP has no image or you cannot access the CLI: Power off the AP. button and power it back on.
Continue holding until the LED turns amber (usually 15–30 seconds), then release. The AP will search for a specific filename (e.g., ap3g1-k9w7-tar.default ) on a TFTP server at IP . Rename your file to match what the AP is looking for. 3. Autonomous vs. Lightweight : Autonomous (Standalone) mode. : Lightweight (Managed by WLC) mode. Conversion between these requires the archive download-sw command to swap the firmware type. Cisco Community If you'd like, I can help you find a TFTP server tool to use or provide the specific LED patterns for the 3500 series to confirm it's in recovery mode.
