We have a fairly old Sonos set-up: Playbar and two Play:3 surrounds, with the TV sound delivered via an optical cable. It used to be rock-solid but, in recent months, it’s become insanely unreliable. For example:The Sonos app can take 5+ seconds to connect. It used to be instant. (Nothing has changed in our networking setup and the problem happened long after we’d upgraded to S2) Sound from the TV will be perfect for days and then it will just start dropping out… eg no sound for 5-20 seconds… and when this happens it happens several times. We changed the optical cable (no improvement) and then thought it was the TV so bought a new one(!) and STILL get the issue. Music played through the Sonos app (eg from Spotify) will also periodically stop. We have a very reliable high speed fibre connection so it’s unlikely to be a connectivity issue.Given the above, I’m convinced it’s the Sonos system that is somehow messed up. Before, going down the support route I figured maybe I should just try to reset the whole thing from scratch. Is that worth trying? If so - and maybe I’m being dumb - how do I do it? I can’t find a guide on how to reset an entire system. I can find articles on how to reset an individual device… but if I want to hard reset EVERYTHING, is there a recipe somewhere I can follow? eg should I reset the surrounds first? Or maybe it doesn’t matter?

That’s a very clean environment.

Your router has a checkered history with SONOS. If you search the community for your router you’ll discover moaning and crying. Make sure that the router’s firmware is up to date and follow this suggestion.

Well, well… that’s very interesting. The router is set to auto-update, but it did have airtime fairness enabled by default. Thanks for the pointer.

Quick update… the problem has not yet recurred. It’s intermittent so I’m not ready to declare success yet but so far, so good. Thanks for all the tips and pointers.
