1. A method implemented by a first wireless device, the method comprising:
switching from operating in a dynamic frequency selection (DFS) master mode to operating in a DFS slave mode upon detecting radar in a first frequency channel, wherein the DFS master mode enables DFS functionality of Radar Interference Detection and transmission control of any wireless device operating in a DFS slave mode, wherein the DFS slave mode disables DFS functionality of Radar Interference Detection;
sending a radar-detected message to a second wireless device over a non-wireless link, wherein the radar-detected message indicates that radar has been detected in the first frequency channel, wherein the non-wireless link is a wired connection;
switching the first wireless device from the first frequency channel to a second frequency channel; and
connecting to the second wireless device in the second frequency channel.
