Multi-network playback devices

A non-transitory computer-readable medium, wherein the non-transitory computer-readable medium is provisioned with program instructions that are executable to cause a playback device to perform functions comprising:

• connecting to a first wireless local area network (WLAN);
• storing, in a network list, a first set of network configuration parameters comprising an identifier of the first WLAN and a first security parameter for the first WLAN;
• disconnecting from the first WLAN;
• after disconnecting from the first WLAN, receiving a second set of network configuration parameters comprising an identifier of a second WLAN and a second security parameter for the second WLAN;
• updating the network list that includes the first set of network configuration parameters by (i) adding the second set of network configuration parameters to the network list and (ii) incrementing a version number of the network list;
• after updating the network list, reconnecting to the first WLAN using the stored first set of network configuration parameters;
• after reconnecting to the first WLAN, transmitting, absent user request, the updated network list to at least one other playback device that is connected to the first WLAN;
• receiving, from the at least one other playback device that is connected to the first WLAN, a second network list stored by the at least one other playback device;
• and
• determining that the incremented version number of the updated network list supersedes a version number of the second network list.

A method carried out by a playback device, the method comprising:

• connecting to a first wireless local area network (WLAN);
• storing, in a network list, a first set of network configuration parameters comprising an identifier of the first WLAN and a first security parameter for the first WLAN;
• disconnecting from the first WLAN;
• after disconnecting from the first WLAN, receiving a second set of network configuration parameters comprising an identifier of a second WLAN and a second security parameter for the second WLAN;
• updating the network list that includes the first set of network configuration parameters by (i) adding the second set of network configuration parameters to the network list and (ii) incrementing a version number of the network list;
• after updating the network list, reconnecting to the first WLAN using the stored first set of network configuration parameters;
• after reconnecting to the first WLAN, transmitting, absent user request, the updated network list to at least one other playback device that is connected to the first WLAN;
• receiving, from the at least one other playback device that is connected to the first WLAN, a second network list stored by the at least one other playback device;
• and
• determining that the incremented version number of the updated network list supersedes a version number of the second network list.
