Abstract

An example computing device includes programming to perform functions including, while operating on a secure WLAN, (a) receiving user input indicating that a user wishes to set up a playback device to operate on the secure WLAN and (b) receiving a first message indicating that a given playback device is available for setup, then transmitting a response to the first message that facilitates establishing an initial communication path with the given playback device outside of the secure WLAN. The functions also include transmitting, to the given playback device via the initial communication path, a second message containing network configuration parameters including an identifier of, and a security key for, the secure WLAN, then detecting an indication that the given playback device has successfully received the network configuration parameters. The functions also include transitioning from communicating with the given playback device via the initial communication path to communicating with the given playback device via the secure WLAN.

Claims

1. A computing device comprising:

a user interface;

a network interface;

at least one processor;

a non-transitory computer-readable medium; and

program instructions stored on the non-transitory computer-readable medium that, when executed by the at least one processor, cause the computing device to perform functions comprising;

while operating on a secure wireless local area network (WLAN), (a) receiving user input indicating that a user wishes to set up a playback device to operate on the secure WLAN and (b) receiving a first message indicating that a given playback device is available for setup;

after receiving the user input and receiving the first message, transmitting a response to the first message that facilitates establishing an initial communication path with the given playback device, wherein the initial communication path is outside of the secure WLAN;

transmitting, to the given playback device via the initial communication path, at least a second message containing network configuration parameters, wherein the network configuration parameters comprise an identifier of the secure WLAN and a security key for the secure WLAN;

after transmitting at least the second message containing the network configuration parameters, detecting an indication that the given playback device has successfully received the network configuration parameters; and

after detecting the indication, transitioning from communicating with the given playback device via the initial communication path to communicating with the given playback device via the secure WLAN.

2. The computing device of claim 1, wherein detecting the indication comprises receiving, from the given playback device via the initial communication path, a third message indicating that the given playback device has successfully received the network configuration parameters.

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

4. The computing device of claim 1, wherein the given playback device comprises an additional playback device to an existing networked audio system.

5. The computing device of claim 1, wherein communicating with the given playback device via the secure WLAN comprises transmitting a command to the given playback device related to playback of audio content.

6. The computing device of claim 5, wherein the command comprises a command to retrieve audio content for playback from an audio source that is accessible via a communication path that includes the secure WLAN.

7. The computing device of claim 1, wherein the computing device is programmed to run a software application for controlling a networked audio system, and wherein the user input is received via the software application.

8. The computing 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 computing device to perform functions comprising:

before transmitting the second message containing the network configuration parameters, obtaining the network configuration parameters.

9. The computing device of claim 8, wherein obtaining the network configuration parameters comprises retrieving the current network configuration parameters of the computing device.

10. The computing device of claim 1, wherein the second message comprises a command for the given playback device to adopt the network configuration parameters.
