Problem adding surrounds to Beam

They are dependent on receiving a signal from the tv. Are you sending a Dolby Digital 5.x signal to the Beam?

I am having the exact same issue. Everything was working perfect until I unplugged and moved speaker temporarily. Went through and made sure I had them all connected on same network. They just don't seem to be able to communicate with each other.  Worked fine yesterday. 

Not sure if this will work for you, but I was having exactly the same problem. I had factory reset multiple times, even swapped out my upstairs Sonos One for the one in the lounge and kept getting the same message.

I got the fail message again with only the right channel added and the left one missing. Turned off my router, turned it back in again and then everything worked again, didn't even have to try to connect surrounds again was already done.

Far from technically knowledgeable but guessing an IP assignment problem from router and the reboot fixed it straight away.

I’ve got the same issue. Tried to add my play 1s, get the error that they can’t be added to check network connection but then they show up beam (?+?) if I remove them then I have to factory reset to add them again and get the same error when I try to add as surround. Diagnostic number 2104789582

Hi @Jadegirl, welcome to the Sonos Community!

Thanks for sending that diagnostic over - looks like you’re using a mesh network is that correct? As these can sometimes cause issues when setting up surrounds, would it be possible to try adding the surrounds with the Beam connected to the network via Ethernet cable?

Let us know how you get on :)

Yes that worked. Thanks

It took me a while to find this thread. I have the exact same issue with a Netgear WAC564 accesspoint. When the Beam is connected through ethernet surround works. Buy as soon as I disconnect ethernet they’re not recognised anymore and schoen as “Living room +?+?". This is unacceptable, because I cannot have a permanent ethernet connetion on the Beam. 

So, are you saying that with my current networks setup I won’t be able tot use the Beam + 2 One’s as surround on wifi?

I experienced the same frustration today, both with the issue at hand, connecting two Sonos One speakers as surrounds to my Arc, and with the poor support responses. “Send us diagnostics”, “tell us about your router”, “it’s probably your WiFi” etc etc. continually avoiding addressing the issue by seeking more and more info.  (Please don’t waste the energy defending this, it’s poor support in my opinion). 
 

The solution I found was as follows. The arc was cable, the Ones were WiFi. I disabled WiFi on the Ones, moved them to the router and connected them via cable to the router.  When I tried adding surrounds on the app, this time, the surrounds setup worked perfectly and the Sonos app added the the Ones to the Arc , I then powered down the Ones, disconnected the cable, moved them back into position and reconnected wifi when I powered therm back up, they remained successfully connected to the arc as surround speakers.

hope this helps someone 

I’m having the same problem adding my One’s to my ARC for surround. Just started this morning after I added a new mesh network yesterday. 

I'm having this problem as well. I have a Beam and 2 Symfonisk bookshelfs from Ikea. For some reason, in the past couple of days one of my speakers stop connecting. I went through the steps to disconnect the speakers as surrounds. I factory reset both, reconnected both and tried to set them back up as surrounds. Just like the OP, "I go thru the setup and it fails saying “There is a problem adding your surrounds. Check the network connection and make sure your products are powered on. Try again.” They are powered on and network is working fine (could play music up until starting the setup).

Pressing “Try again” instantly gets the same error. If I exit the setup, the Living Room (where the Beam is) now says “Living Room (+?+?)” and I have “Remove Surrounds” in the rooms menu."
