Connect the console cable to the AP and your computer. Use the following serial parameters:
The safest and only official method to acquire the legitimate binary archive is through the Cisco Software Central Portal . Cisco Entitlement Protocols
If you are performing a conversion, follow this general procedure documented by Cisco Community experts :
The typical workflow involves entering the AP's ROMMON (Read-Only Memory Monitor) mode during the boot process. From there, the engineer sets environment variables (such as IP_ADDRESS and DEFAULT_GATEWAY ) and issues the tar command to extract and load the AP3G1-K9W7-TAR.152-2.JB.tar file directly into flash memory. This process overwrites the previous Lightweight image (often denoted by a rcv or w8 suffix in the existing filename). Once the transfer is complete and the device reboots, the Access Point operates as an independent node, allowing for full CLI configuration of SSIDs, security settings, and radio parameters without a controller.

If your switch port is set to switchport port-security , the rapid Mac address change during the recovery can disable the port.

Let's decode it piece by piece.
Note: If your file contains k9w8 or rcvk9w8 , it is a Controller-managed or Recovery image and will not function as a standalone router. 💾 How to Secure the Download
ap3g1-k9w7-tar.152-2.jb.tar is an IOS image for the (and the closely related 1260 Series). It allows a lightweight (CAPWAP‑based) access point to be converted into a fully autonomous (standalone) access point . For many network engineers and lab users, this file is the key to unlocking the AP’s potential without having to maintain a separate wireless controller.
Where can you safely download this file? Cisco has moved this image to status, meaning it is no longer on Cisco's main software download portal for non-contract holders. Here are the legitimate options: Connect the console cable to the AP and your computer
