I have two Sonos systems: (i) one in a completely detached house, with high-speed internet (1gig download / 16 upload) consisting of two Play 1s and two Sonos Roams, 1 gateway router, and 1 additional hardwired router, and a Beacon; and (ii) a second system in a city apartment also with high speed internet (300mbps / 17 upload) consisting of 1 Sonos Beam, 2 Play One SL, one Roam, 1 gateway router, 2 additional hard-wired routers.
All of the residence were professionally wired, and not DIY. In each case -- 5 years plus in the apartment, and 1 year plus in the house -- one or more speakers regularly lose connection without any discernible pattern, and Roams seems to totally disconnect from the system after a few days of non use.
TO ME, CLEARLY, ONE OR MORE OF SONOS SOFTWARE, FIRMWARE, OR APP IS FAULY AND CONTINUES TO BE FAULTY. I have a very demanding job and do not have additional hours to spend on the phone with Sonos Technical support...and so, I live with the frustration of the frequent speaker drops. As with all providers of high-tech products, issues that cannot be fixed by the provider are often said to lie with the consumer’s connections, network, user error, internet service provider, etc.
We all remember the problems that the like of AT&T, Verizon, etc. encountered over the years that were later shown to be the fault of the provider exposed by class action, FTC, or other litigation. I wouldn't be surprised if in the very near future, Sonos is shown to have knowingly failed to recognize and knowingly failed to remedy software and firmware issues. Until then, we the Sonos users grin and bear it because all the other consumer wireless speaker systems are equally buggy. send]
