I want to smash this system

I do have every sympathy with you. Sonos may feel that putting 18 Roams on a system is fine. I am just a fellow user and a huge Sonos fan but I agree with you that you should have been challenged as to whether you had chosen the best option.

I would go back to Sonos and challenge them on this. Maybe they will make some sort of concession??

I would be interested to know if any other contributors were as surprised as I was by 18 Roams in a system?

When I read the opening post I genuinely could not believe someone actually recommended this as a solution, even if they were on commission.

Me too - especially in a “commercial” - or at least non-domestic - environment.
 

“Cheaper than running cables” may have been someone’s conclusion, pre installation?

I was slightly taken aback when I read the system was 18 Roams. I don’t recall ever seeing another thread where such a large system was entirely portable speakers. Then I thought what happens when the battery goes in the speaker…

Yep, I was surprised …and personally would not choose to use a wireless-only battery-rechargeable speaker system in a multi-room corporate/business environment, particularly where there are lots of Staff/Customers milling about, unless (as a very last resort) I could perhaps raise up those speakers, or/and set a number of bridged WiFi AP’s (wired back to the main router) over head-height.

My own choice though would have been a wired setup, using either in-wall and/or in-ceiling speakers with room volume controls linked back to multizone amps and perhaps use those with Sonos port(s). Certainly more expensive, but clearly connection-reliability will always come at a cost.

@Ca.tree.an . Hopefully that gives you some ammunition. I am a huge fan of Sonos and my system works brilliantly. But you seem to have have been poorly advised. 

It wouldn’t be my suggestion, that’s for sure. 

@Ca.tree.an

I agree that this was not a good system design. Was voice control of each room a design consideration?

I’m also not in favor of eero WiFi for this sort of network. I suggest that you go to eero Advanced and reserve IP addresses for all regular network clients -- especially the SONOS units. Your intermittent SONOS issues could be related to SONOS updates causing duplicate IP addresses. Reservations will prevent this. Over a period of days the duplicate IP address issue may resolve itself. This (potential) self resolution creates lots of confusion for the poor user because user will be trying other approaches along the way and may decide that resolution ‘A’ is the magic bullet, when ‘A’ accidentally coincided with self resolution, but ‘A’ will not work the next time.

Note that the “reboot everything” (in the proper sequence) will usually cure the duplicate IP address issue in the short term, but reservations will prevent duplicates in the future.
