Option to disable built-in WiFi, when Sonos is used as a single device.

There are certain users, who don't utilize multi-zone capabilities, since they've picked up just a single Sonos player - be it Connect or Play - for one-room music experience. Naturally, those users don't need to keep the built-in WiFi in always ON state. Please, consider adding an option to disable WiFi, when it is not required. This will reduce power consumption, interference with other wifi sources, and keep the environment clean and free of extra EMR.
