Sonos Devices Connecting to Multiple Networks

Not too long ago, we switched from an Eero mesh network to Araknis access points to extend WiFi coverage throughout our home while we had AT&T. We’ve since switched to Spectrum, removed the Araknis system, and gone back to using our Eero mesh network.

 

We currently have the Spectrum router/modem connected to our Eero system, similar to how we previously had AT&T set up.

 

We also had third-party technicians install amps for our outdoor Sonos system as well as the Araknis system, but the Araknis ended up making our WiFi worse, so we removed the Araknis and AT&t and set up the Eero system again with a Spectrum router and modem.

 

Now the issue is that our Sonos system seems to be detecting two separate WiFi networks. The router’s WiFi (connected via Ethernet) is working with our two amps, but the other Sonos devices inside the house keep switching to the extender network. In the app, they frequently show as “not connected,” even after updating the network settings

 

About 2-3 weeks ago, by pure luck, I finally got all the devices on the same Spectrum system. However, we had a pretty heavy thunderstorm and the power went out.. when that happened a full reset of the Sonos system took place and all the devices besides the amps (connected via Ethernet to router) lost their connection to the Spectrum system. 
 

if somebody has experienced this before please let me know!! 
 

thank you

    Disable the WiFi on the ‘other’ system, leave the spectrum running as is. Unplug all Sonos devices from power, then reboot the Spectrum router. Wait two minutes, then plug back in the Sonos. They should connect to the only ‘existing’ WiFi signal, generated by your Spectrum, as should any controller devices. 

    Honestly, I’m confused as to what the ‘other’ system is that’s showing up, much less why it is still connected. It sure sounds like whomever you had ‘fix’ things did a poor job. There should only be one WiFi signal (that you manage) in your home. There can (will be ) others, most likely run by your neighbors or others close to you, but your home should only have one.

    Oh, I see you have eero. So disable the WiFi on the Spectrum, and make sure all devices are connected to the eero signal. Your Spectrum device should not be emitting a WiFi signal at all, it should just be providing a WAN(LAN) connection to your eero. The Sonos should be connected to the eero.

    This might be a helpful thread for you, particularly the first post:

    I read a lot about Spectrum and Sonos not working well together.  So ​as @Airgetlam suggested put the Spectrum in Bridge Mode and then EERO will be the WiFi you connect to.  Bridge Mode turns off the Spectrum WiFi.

      Minor but important:

      However, we had a pretty heavy thunderstorm and the power went out.. when that happened a full reset of the Sonos system

      What you got was a reboot, not a reset. A reset clears ALL Sonos information and you must set the whole system up from the beginning.

       router’s WiFi (connected via Ethernet) is working with our two amps, 

      And

      the amps (connected via Ethernet to router)

       

      If the Amps aren't using Ethernet or you have selected the "disable wifi" setting on them you can ignore this bit. When wired compatible Sonos devices creat a 2.4 gHz Sonosnet that other compatible Sonos will select in preference to your Wi-Fi,  usually not a good thing today. The 2.4 gHz Sonosnet is old, slower and less reliable technology and isn't supported on newer Sonos so it complicates things, aside from requiring a dedicated wifi channel.
