I just received my Sonos One and am trying to set it up. The very first thing I saw was this message: "There was a problem confirming if your Sonos controller is up-to-date. If you continue and your controller is not up-to-date, you will be unable to set up certain Sonos products." I tried the wireless set up and it didn't work and now I am trying to connect directly to my router with the Ethernet cable. That worked and I got through the setup, but now that I have unplugged it, removed the Ethernet cable and moved it, it can't find it. Any suggestions? This is very disappointing as I'd heard such great things about Sonos.
