Wait for extraction. Then reboot:

ap: boot

Method C: Autonomous to Lightweight Conversion

Some AP1G3 units can run both. If currently autonomous (K9W8):

Obtain AP1G3-K9W7-TAR.

Use the same bootloader TFTP method but ensure config sector is cleared:

ap: clear config
ap: set IP_ADDR ...
ap: tar -xtract tftp://... flash:

⚠️ This erases all previous configuration.

6. Important Cautions

Check your AP model – Not all ap1g3 images work on every AP in that family. Verify compatibility.
Memory requirements – Ensure the AP has enough flash/DRAM for the image.
Bootloader version – Some updates require a bootloader upgrade first.
Regulatory domain – The k9w7 may not include your country’s regulatory settings; check if a specific regulatory file is needed.

If you can provide the full filename (e.g., ap1g3-k9w7-tar.153-3.JP.tar) and your AP model (e.g., 2602i, 3602e), I can give more specific upgrade steps or tell you if that file suits your hardware.

The filename ap1g3-k9w7-tar refers to a specific Cisco IOS software image for an Autonomous Access Point (AP). This file is primarily associated with industrial and outdoor wireless hardware, such as the Cisco Aironet 1530 Series and integrated modules like the AP803 found in Cisco IR829 and IR809 routers. File Name Breakdown ap1g3-k9w7-tar

ap1g3: Identifies the hardware generation/platform, typically associated with Cisco's industrial and outdoor AP series.

k9w7: Specifies the software capability and mode. "k9" indicates strong encryption, while "w7" denotes Autonomous mode, meaning the AP operates independently without a Wireless LAN Controller (WLC).

tar: The file format (Tape Archive), which contains the executable image, HTML management files, and radio firmware. Key Technical Specifications Supported Devices

Hold Reset button for 20–30 seconds during power cycle to force a TFTP download Practical Use Cases

Industrial Routing: In the Cisco IR829 series, this image allows the integrated AP803 module to provide localized Wi-Fi for industrial vehicles or remote sites without requiring a central controller.

Outdoor Deployments: Used for the Aironet 1530 series to bridge networks or provide hot-spots in harsh environments.

Mode Conversion: This file is often used to convert an AP from "Lightweight" (w8) mode back to "Autonomous" (w7) mode. Installation & Recovery Wait for extraction

To install this software on a device in a recovery state, a TFTP server must be set up at a specific IP (usually in the 10.0.0.2 to 10.0.0.30 range). Pressing the Reset button for approximately 20 to 30 seconds during power-up triggers the AP to look for the ap1g3-k9w7-tar.default file on the TFTP server to re-image itself.
