I just set up my Sonos One yesterday, and when I tried to play my first song it disconnected from wifi and hasn't reconnected. Not only that, but I tried to factory reset it by holding the infinity button while reconnecting power, but that didn't seem to work. Now, when I plug it into a power source, the little light doesn't even turn on. What should I do?

Try rebooting your router and resetting the One while it is connected directly to your router with an ethernet cable.
