If you’ve recently picked up a used Cisco Aironet 3502i (part of the AP3G1 family) or are repurposing old enterprise gear for a home lab, you’ve likely run into a major hurdle: the "Lightweight" firmware. By default, these units expect a Wireless LAN Controller to tell them what to do.

Accessing and downloading software from the official Cisco Software Center requires an active support contract and valid Cisco CCO credentials.

The 15.3(3)JF train was a significant release for the Aironet 3600/3700 series. Here is what JF15 specifically improves:
