Re-establishing player connectivity

A method to be performed by a first playback device comprising a wireless network interface, one or more processors, a housing carrying the wireless network interface, the one or more processors, and data storage having stored therein first network parameters comprising (i) a service set identifier (SSID) identifying a first wireless local area network (WLAN) provided by a first access point, (ii) a first wireless channel of the first WLAN, and (iii) an IP address in a first subnet, the method comprising:

• after a power cycle of the first playback device, attempt to re-establish a network connection over the first WLAN using the first network parameters stored in the data storage;
• determining that the first access point has been replaced with a second access point, wherein the first playback device previously established a valid network connection over the first WLAN using the first network parameters;
• connecting to the second access point, the second access point providing a second WLAN;
• requesting, via the wireless network interface from the second access point, an IP address in a second subnet, the second subnet covering a different range of IP addresses than the first subnet;
• and
• establishing a network connection over the second WLAN using second network parameters stored in the data storage of the first playback device, the second network parameters comprising (i) a SSID identifying the second WLAN, (ii) a second wireless channel, (iii) an IP address in the second subnet, wherein, after establishing the network connection over the second WLAN, the first playback device is configured to attempt to re-establish the network connection over the second WLAN using the second network parameters stored in the data storage after power cycles of the first playback device.

A non-transitory computer-readable medium having instructions executable by one or more processors to cause a first playback device to perform functions, the first playback device having stored, in data storage of the first playback device, first network parameters comprising (i) a service set identifier (SSID) identifying a first wireless local area network (WLAN) provided by a first access point, (ii) a first wireless channel of the first WLAN, and (iii) an IP address in a first subnet, the functions comprising:

• after a power cycle of the first playback device, attempt to re-establish a network connection over the first WLAN using the first network parameters stored in the data storage;
• determining that the first access point has been replaced with a second access point, wherein the first playback device previously established a valid network connection over the first WLAN using the first network parameters;
• connecting to the second access point, the second access point providing a second WLAN;
• requesting, via a wireless network interface from the second access point, an IP address in a second subnet, the second subnet covering a different range of IP addresses than the first subnet;
• and
• establishing a network connection over the second WLAN using second network parameters stored in the data storage of the first playback device, the second network parameters comprising (i) a SSID identifying the second WLAN, (ii) a second wireless channel, (iii) an IP address in the second subnet, wherein, after establishing the network connection over the second WLAN, the first playback device is configured to attempt to re-establish the network connection over the second WLAN using the second network parameters stored in the data storage after power cycles of the first playback device.
