An example implementation involves a first playback device receiving, from a remote server over a wide area network, a configuration table corresponding to a secure network comprising the first playback device. The first playback device determines that the configuration table comprises an entry corresponding to a second playback device that is not part of the secure network. The first playback device listens, over an unsecure local area network, for transmissions from playback devices, and, while listening, receives a first message from the second playback device, the first message indicating that the second playback device is available to join the secure network. In response to receiving the first message, the first playback device transmits, to the second playback device over the unsecure local area network, a second message comprising configuration information for the second playback device to join the secure network.
