Abstract

Techniques for automatically configuring necessary parameters of a device to be coupled to a network with minimum human intervention are disclosed. In one embodiment, a wired and/or wireless Ad-hoc network is established to facilitate communications among a group of devices. When a new device is added to the network, a rudimentary communication path is initially established between one of the devices in the network and the new device such that necessary parameters (e.g., SSID, WEP security, channel frequency) can be exchanged for the new device to function properly in the network. To ensure the parameters are exchanged in a secure fashion, an additional public security procedure can be used between the two devices.

Claims

1. A method of connecting a device to a secure network for one or more playback devices, the method comprising:

receiving a manual user action at a zone player that is unconfigured for a secure network, wherein the manual user action initiates an automatic establishment of a connection to the secure network by the zone player;

transmitting, by the zone player responsive to the manual user action, a first message over an unsecure network to be received by a device configured for the secure network, wherein the first message indicates that the zone player is available to join the secure network;

receiving, over the unsecure network by the zone player, a second message from the device, wherein the second message is generated responsive to receipt of the first message and wherein the second message includes a security parameter to be used by the zone player to join the secure network; and

establishing a connection to the secure network by the zone player using the security parameter without further input by any user via either the zone player or the device.

2. The method of claim 1, further comprising receiving audio content by the zone player over the secure network and playing back the audio content via the zone player.

3. The method of claim 1, wherein the security parameter is generated by the device.

4. The method of claim 1, wherein the security parameter comprises a wired equivalent privacy (WEP) key.

5. The method of claim 1, wherein the security parameter comprises a household identifier (HHID).

6. The method of claim 1, wherein the user command corresponds to a manual button press on the zone player.

7. The method of claim 1, wherein the device comprises a controller for the zone player.

8. The method of claim 1, wherein the device comprises a second zone player.

9. The method of claim 1, further comprising transmitting, via the zone player, audio content to another zone player.

10. The method of claim 1, wherein the device is triggered to hear the first message.

11. The method of claim 1, further comprising receiving, over the unsecure network by the zone player, a request from the device to the zone player to respond with the zone player'"'"'s current network configuration information.

12. The method of claim 11, further comprising transmitting, over the unsecure network by the zone player, a response to the device by the zone player including the zone player'"'"'s network configuration information.

13. The method of claim 1, wherein the second message comprises a command message from the device to the zone player to reconfigure the zone player'"'"'s network configuration information.

14. The method of claim 13, further comprising transmitting, by the zone player, a third message including a response indicating that the zone player'"'"'s network configuration information has been changed according to the command message from the device.

15. A non-transitory computer-readable storage medium including a set of instructions for execution by a processor, the set of instructions, when executed, facilitating connection of a device to a secure network via a method comprising:

receiving a manual user action at a zone player that is unconfigured for a secure network, wherein the manual user action initiates an automatic establishment of a connection to the secure network by the zone player;

transmitting, by the zone player responsive to the manual user action, a first message over an unsecure network to be received by a device configured for the secure network, wherein the first message indicates that the zone player is available to join the secure network;

receiving, over the unsecure network by the zone player, a second message from the device, wherein the second message is generated responsive to receipt of the first message and wherein the second message includes a security parameter to be used by the zone player to join the secure network; and

establishing a connection to the secure network by the zone player using the security parameter without further input by any user via either the zone player or the device.

16. The computer-readable medium of claim 15, wherein the security parameter is generated by the device.

17. The computer-readable medium of claim 15, wherein the security parameter comprises a wired equivalent privacy (WEP) key.

18. The computer-readable medium of claim 15, wherein the security parameter comprises a household identifier (HHID).

19. The computer-readable medium of claim 15, wherein the manual user action corresponds to a manual button press on the zone player.

20. The computer-readable medium of claim 15, wherein the device is triggered to hear the first message from the zone player.

21. The computer-readable medium of claim 15, further comprising receiving, over the unsecure network by the zone player, a request from the device to the zone player to respond with the zone player'"'"'s current network configuration information.

22. The computer-readable medium of claim 21, further comprising transmitting, over the unsecure network by the zone player, a response to the device by the zone player including the zone player'"'"'s network configuration information.

23. The computer-readable medium of claim 15, wherein the second message comprises a command message from the device to the zone player to reconfigure the zone player'"'"'s network configuration information.
