Your profile shows a number of devices. Were you having problems that you are hoping to solve with the boost? Are you running on wifi or SonosNet? 

Rule of thumb is at least one meter from potentially interfering units.

Is your BOOST wired or wireless? If you are using a wireless BOOST to cover a difficult, distant area, place the wireless BOOST about midway between a stable SonosNet area and the difficult location.

It should be positioned 3 feet (100 centimeters) away from any other radio waves emitting device. If that isn’t possible, it's just trial and error.

Thanks from the reply, we were on the old connect /Wi-Fi in a previous home. We have moved and I’m in the process of adding new additional components. An AV contact suggested that we get the Boost to ensure reliable coverage. I’m not sure what it’s on and/ or how to check and/or what’s best. 
 

thanks again.

The Boost really doesn’t add much if you are able to wire one or more other Sonos devices (not Subs or Surrounds) to your router.

Also if you shop for a Boost you’ll find it on the Sonos “Last Chance” page.

As @Stanley_4 says, you may be ok with just your speakers. Try without the boost. If all is good, return it. 

Thanks for the feedback. I can’t even get it to connect at the moment so that might be a better option. The thinking was 10+ speakers might benefit from the additional investment of a boost. 
think I’ll get the other bit set up and assess from there. 
 

thanks again.

BOOST simply contains the radios, but no audio processing. This reduces costs. As far as helping network connectivity, its communication performance is no different than a regular player installed at the given location. BOOST is most often used when you don’t want a player located at the most convenient wired network port. Another use would be to support a wireless player that is otherwise out of range. In very difficult situations a wireless BOOST could be placed about midway between a distant wireless player a good coverage area.

This could be very helpful- thank you. 
If I understand correctly, I could plug the boost into a network socket away from the Wi-Fi router to increase coverage? 
 

is it best to connect one of the other devices by cable rather than rely on Wi-Fi. They are all on Wi-Fi at the moment. 
 

Are you experiencing any issues? Many of us prefer SonosNet, but if the system works with WiFi there is no need to change anything.

The Boost will not increase coverage of your WiFi as it replaces it with the Sonosnet wireless signal. I think the Move and Roam will still use your WiFi, don’t have either.

I have a Boost sitting in a drawer, once I wired a couple other Sonos I could see that none of my un-wired Sonos were connecting to the Boost.

If you have other wired Sonos you could use a Boost to extend the range of the connection they are offering, or if wired give you an additional connection point for other wireless Sonos.

Almost always wasted money and power draw these days but in a few special situations it has a purpose. I’d start without it and look at your internal data, maybe even send Sonos a diagnostic and discuss it with them before adding a Boost.

Once a Sonos is wired try the Sonos Network Matrix, replace my 172.xxx IP with yours, keep the :1400 part.

It should look like this (shrunk too far to be usable) and let you see what your connections are. If you want help with yours you can post one (large enough for folks to read the print) and you’ll usually get some good advice.

Thank you. Very comprehensive and techy / detailed. Sorry to ask such a basic question but where can I easily find my IP address to drop it in the link. 
 

thanks again. 

Your router should have IP information, either under the DNS or DHCP settings pages.
