Abstract

An example playback device includes programming to perform functions including detecting a triggering event that causes the playback device to transmit a first message indicating that the playback device is available for setup. The functions also include receiving a response to the first message that facilitates establishing an initial communication path with a computing device operating on a secure wireless local area network (WLAN), where the initial communication path is outside of the secure WLAN. The functions also include receiving, from the computing device via the initial communication path, a second message containing network configuration parameters for the secure WLAN including an identifier of, and a security key for, the secure WLAN. The functions also include using the network configuration parameters to connect to the secure WLAN and transitioning from communicating with the computing device via the initial communication path to communicating with the computing device via the secure WLAN.

2. The playback device of claim 1, wherein the triggering event comprises one of (a) powering on the playback device or (b) receiving user input via a physical interface of the playback device.

3. The playback device of claim 1, wherein the computing device comprises a controller device of a networked audio system.

4. The playback device of claim 1, further comprising program instructions stored on the non-transitory computer-readable medium that, when executed by the at least one processor, cause the playback device to perform functions comprising:

after receiving the second message, providing an indication that the playback device has successfully received the network configuration parameters for the secure WLAN.

5. The playback device of claim 4, wherein providing the indication comprises transmitting, to the computing device via the initial communication path, at least a third message indicating that the playback device has successfully received the network configuration parameters;

6. The playback device of claim 4, wherein providing the indication comprises providing an indication that the playback device has successfully connected to the secure WLAN using the network configuration parameters.

7. The playback device of claim 1, further comprising program instructions stored on the non-transitory computer-readable medium that, when executed by the at least one processor, cause the playback device to perform functions comprising:

after connecting to the secure WLAN, establishing a new networked audio system on the secure WLAN.

8. The playback device of claim 1, further comprising program instructions stored on the non-transitory computer-readable medium that, when executed by the at least one processor, cause the playback device to perform functions comprising:
