Existing system not found

I lost my connection to Sonos.  Now, when I try to connect with my iPhone, I get the Existing System Not Found message and when I ‘press and release’ the button nothing happens.  When I try to access Sonos from my tablet I get the ‘Sorry, we can connect to Sonos’ message.  I’ve tried resetting the router: still nothing.  Any ideas?

The next thing I would try as a troubleshooting step would be to wire a Sonos device to my router (if I didn’t already have one wired) and to wire a different Sonos device (if one already wired).  Give it a few minutes to reconfigure then post back with the outcome.

Sonos failed again !!!

It seemed to work a couple of hours ago as the App found the Sonos system again. Now that I want to play some music, it bugs out the same way again ...

My Sonos Boost was wired to the router, but I tried connecting a Sonos Connect to the router and rebooting everything.  No luck.  So I connected a Sonos Play:5 to the router.  And I have music!

But only through the Sonos Play:5.  The Sonos Connect appears in my Plume WiFi app as connect,  it the (now disconnected) Boost doesn’t show up.

What do you make of that?

Do you still have a speaker wired?

I had disconnected the speaker again. In frustration, yesterday evening I drew a cable between the floors of our house to permanently hardwire my Sonos Connect. That solved the problem yesterday, we had music. Today however, it’s all the same again!

Try unplugging all Sonos devices from power, then reboot your router. When the router comes back up, plug back in all Sonos devices.
 

Note that all Sonos devices must be unplugged during the router reboot, otherwise you’re only getting some, not all, of the benefits of the procedure.

I’ll try that, but at the same time I’m wondering why this happens now, and repeatedly? I’ve had the exact same system with the same router several years now, and never had this issue. Nothing has been changed, it happened out of the blue ...

Ok, it works again (just like yesterday), but what about tomorrow? Will I have to go through this procedure every day now???

@Ziggy66 : Try setting fixed adresses for your Sonos units in your router’s DHCP table.

When done, refresh your system as descibed above by Airgetlam.

This happens to me a lot! I mostly get satisfaction when I restart my eero network, but sometimes it just doesn't connect. I’ll give up and return the next day to see it miraculously working again...until the next time. I get tired of playing these games and only want my system to work more often. Ready to try another ecosystem.

I fixed this problem by “bridging” my eero in advanced settings.
