The order in which you replace your wired Bridge with your new Boost is really important. To avoid wiping out all of the work you've done to make your Sonos system uniquely yours, perform the steps below. BTW, the same process works if you're replacing your wired Bridge with another wired Bridge.
Some users will end up physically swapping their Bridge out with the Boost in the wrong order, then erroneously setting up their Sonos system once again from scratch - thinking that's what they're supposed to do, performing button presses on their speakers, adding room names back - unaware of the ramifications. Don't do it that way or you'll lose all of your personalized Sonos settings. Gone will be your favorite radio stations, you'll have to add you music subscription information back in from scratch, you'll even have to set up your music library again.
In order to maintain your existing room names, music subscriptions, custom radio stations and Sonos favorites, do this:
1) Do Not
unplug your Bridge from power or the router just yet. Your Sonos system should be exactly how it normally is, with the Bridge wired to your router.
2) Plug the power into the Boost, give it around 30 seconds to boot up. You'll see the blinking green light on it. This indicates it is a new component that has not yet been added to your Sonos system. Don't wire it to your router yet. Wireless is fine at the moment.
3) Go into the Sonos software and choose the option to add the Boost. On a PC or Mac, it's under Manage > Add a Bridge or Boost
. On a iPhone or tablet, it's under Settings > Add a Bridge or Boost
You'll then be presented with the options Wired to Your Router
and Use Somewhere Else
. Either choice is OK, just don't
wire it to your router when prompted to. Sonos will see the button press and add the Boost. The LED on the Boost will stop blinking green and go to solid white when it has been added successfully.
4) Finally, physically swap the Bridge with the Boost. You're done, and your Sonos favorites, subscriptions, etc are still intact.
You can always use the Bridge wirelessly as a signal booster for the Sonos components in a different area of your home. Use it to get a signal out to your garage, patio, pool, etc if you ever take a player outside to use for the day. It will be a good way of ensuring you won't get audio interruptions during an outdoor celebration. Just plug it into power on the inside wall that's closest to your outdoor area and you can leave it. Or store it with the power supply and bring it back out if the Boost ever malfunctions.
The new Sonos software automatically gives the wired component root bridge status, so the Boost will become the root device in your Sonos system.
You might be able to have the Boost wired in when adding it in the Sonos software, but err on the safe side by adding it wirelessly, then doing the swaperoo with the Bridge when complete.
