The surrounds have recently dropped off my ‘upstairs’ system and I keep getting ‘there was a problem adding….’

this is my set up.

Downstairs: playbar (wired to router), sub v2 and 2x play 1’s - working fine.

Upstairs: Arc, Sub v3, One SL and a One v1.   The surrounds had a sulk and dropped off when I changed our Wi-Fi network and won’t re-connect.    They are functioning correctly as individual speakers and will stereo pair but won’t reconnect as rear surrounds.

all the firmware is up to date including a roam and move.  I’ve restarted all the speakers on this system and am now at a loss.

When I try and add, I get the chime from one of the rears, but then it fails.

any suggestions welcome.

If you changed your router, and along with it your SSID, the easiest thing to do would be to change the SSID and password back to what it was on your old router.

If that is not possible and you are able to wire the Arc to your router, that should also solve your issue.

Have you removed the stereo pair link before trying to add the Ones as surrounds?

thanks for the reply.

Yes, stereo pair link is removed.

I’m unable to directly wire the arc to the router as they are on different floors.  I could try and cable it to one of the mesh nodes - wonder if that would work…

I can’t see why a different Wi-Fi network would stop it functioning, and I thought only one of the speakers needed to be on a wired connection to allow the Sonos network to function.

The app has the ability to update your WIFI settings on the Arc, but it requires user intervention. Since changing your WIFI network caused the problem, that would mean that the Arc was NOT using Sonosnet to connect to your network. It was using your WIFI.

So you either have to:

  1. update your WIFI settings from within the app
  2. Hardwire the Arc to your network
  3. Reset your Arc and add the surrounds and Sub again.

Power down all Sonos, reboot router, Power up the Ethernet connected Sonos. Wait for it to wake up and then power up the rest of the Sonos.

Sometimes there are IP address issues that this will clear.

It almost sounds like you may have the two problem surrounds set up as a second Sonos system, can you Group them with another Sonos to make sure that isn’t an issue?

After that, I’d call Sonos support after submitting a diagnostic and have them look at the internal data for clues. (don’t post the diag number here)

 

I’m think I got somewhere last night.   Having gone through all the speakers, I found the playbar that is connected to the router still had its wifi enabled.   After disabling that the surrounds on the arc connected - although they immediately dropped off again.   Still need to figure that one out.

Sonos soundbars create their own 5ghz network to connect to the surrounds and sub to ‘bond’ them all together to keep them in sync. If you turn off WiFi on the Playbar, this 5ghz WiFi can’t be created and so the surrounds will disconnect.

Sorted now - factory reset the arc, the sub and surrounds then added correctly.

Thank you all for the suggestions.
