Hi,
As per the link “system requirements” which is also included in the link provided above by @Simon B, ethernet over power is not supported. Can you wire one of your speakers (not the surrounds) with an ethernet cable to the router?

Also pay attention to the “group coordinator” as explained here: https://en.community.sonos.com/controllers-software-228995/sonos-group-coordinator-question-6803946

@ClausN @Simon B 

Hi and thanks both. 
 

unfortunately, there no way to wire an Ethernet directly to the switch without the power line. It’s tucked away in a server room.

didn’t know they didn’t play well together. Will reset to wifi and try that 

Hi @Mister Knights, thanks for the update. Let us know how it goes for our suggestions and see if that ill work. If you have any questions or run into any other issues, please do not hesitate to contact us. We are always happy to assist you.

Hi Simon, I think best option is a boost and to remove the power line. Do you agree? 

Hi @Mister Knights, thanks for the update. About your question on the Sonos Boost, since you have the Sonos Beam hardwired. It may have the same effect on your system. Or another option would be trying to hardwire one of your speakers to the router aside from the Beam. A Sonos Play 1 would work, not the one’s on the surrounds, to check if it will have the same effect. 

Let us know what you have in mind with the advice above.

We're here to answer any further questions you have.

@Simon B 

i meant in the room with the network switch and router. Connecting the system via the boost, which is hard wired to the switch. 
 

theres no way to hard wire a P1. Otherwise it would be in a room, and unusable
