This does not make a lot of sense to me. Did support give a reason? Is the wireless environment very bad in the current location?
EoP is my last choice for networking, but it will occasionally be the miracle cure. Old houses with multiple electrical panels are risky. EoP usually works best if the two circuits are in the same breaker column in the electrical panel. Finally, heavy duty surge surge suppressors in the same outlet as an EoP endpoint usually cause trouble. That said, there can be miracles.
Hi @lordwanswell
The link will answer your question regarding use of EoP. It’s not recommended.

I believe you can still purchase a $99 (USD) Boost module from Sonos. The Boost module will allow you to create the SonosNet when wiring a speaker to your router is not practical.
Edit: You can also purchase a used Play 1 on eBay that you can wire to your router to create the SonosNet plus you‘ll have another speaker.
Thanks for the advice, buzz and AjTrek1. I will drop the EoP idea. I particularly like the idea of buying a used Sonos 1, rather than a Boost.
