Use the archive download-sw command to point the AP to your TFTP server's IP address and pull the TAR file. For example: archive download-sw /overwrite /reload tftp://192.168.1.5/ap1g2-k9w7-tar.153-3.JF15.tar
When converting a lightweight AP to autonomous, you will download a tar file. However, you may also encounter .aes files (for WLCs) or files named like ap1g2-k9w7-mx.152-2.JB2 . The MX in the name usually indicates a "M**xed" or merged image that can be used for conversion.
The AP will extract the files, write them to flash, and reboot into a standalone state. Common Troubleshooting
signifies "Autonomous" mode . This means the AP operates as a standalone device with its own management interface, rather than being managed by a central Wireless LAN Controller (WLC).

: Refers to the hardware platform group, specifically the Aironet 1600 and 1602 series.
The AP will take several minutes to flash, unzip, and reboot.
To install this image and convert an AP to standalone mode, engineers typically use a TFTP server and the following manual recovery process: Cisco Community Preparation : Download the image (e.g., ap1g2-k9w7-tar.153-3.JF15.tar ) and rename it to ap1g2-k9w7-tar.default TFTP Setup : Place the file in the root directory of a TFTP server. Hardware Trigger Disconnect power from the access point. Press and hold the MODE button while reconnecting power.
Expected output: AP running image: ap1g2-k9w7-tar.xxx Use the archive download-sw command to point the
: Denotes the operational feature set. In Cisco vocabulary, w7 explicitly signifies Autonomous (Standalone) IOS capability. Conversely, a w8 identifier indicates a Lightweight (Controller-managed) operational mode.
The designation follows a systematic naming convention that reveals its structure and function:
Choosing k9w7 is essential for networks without a WLC, making it a versatile choice for small to medium-sized businesses, remote offices, or dedicated testing environments.
Before downloading or flashing an access point, you must understand the difference between the two primary management paradigms: Autonomous Mode ( k9w7 ) Lightweight Mode ( k9w8 ) Standalone device. Centralized management. Control Plane Managed locally per AP via CLI or Web GUI. Managed via a Wireless LAN Controller (WLC). Best Used For Home labs, small offices, isolated test beds. Large enterprise campuses, complex multi-AP roaming. Dependencies Requires zero additional hardware. Will not broadcast SSIDs without an active WLC connection. The MX in the name usually indicates a
This is the file extension. Unlike a simple .bin file, a .tar file contains the image plus the necessary HTML management files (the GUI). Autonomous vs. Lightweight (w7 vs. w8)
Signifies that this is an Autonomous (Standalone) image. Access points using this image can be configured and managed individually without a Wireless LAN Controller (WLC). (In contrast, w8 images are "Lightweight" and require a controller to function).
The default IP will often revert to if it doesn't find a DHCP server . Important Note Looking for Cisco Aironet 1602 autonomous firmware (k9w7)
The AP will automatically search for 10.0.0.2 (or broadcast) and download the ap1g2-k9w7-tar.default file to reflash itself.
