Ethernet Setup

I have sonosnet disabled and have the supplied fios CR1000B, extender and moca adapter all connected as my home networking setup. 
 

The Sonos one sl is now connected to the moca adapter upstairs and will no longer show up on the network or in the Sonos app. On WiFi it comes back no problem. 
 

Any ideas or troubleshooting tips are welcomed. Thanks

Well, that is a true extender (which sonos does not support). I’m not familiar with Verizon/Fios equipment, but maybe someone who is will have some advice for you.

But, as far as the wired speaker appearing and disappearing from the network, I’d lean towards a coax/moca related connection problem. As a test, you could connect it directly to the router LAN port and see if it has the same problem.

If it has problems wired directly to the router, take ​@Smilja advice and contact sonos support.

My guess, without looking it up, is your extender is creating a separate subnet. Sonos requires all devices to be on the same subnet, so you should look at the manual for your CR1000B and see how to set up any ‘extensions’ as the same subnet.

Alternately, you could call Sonos Support to discuss it.

When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

    Sonos explicitly do NOT support wifi extenders. Use a mesh system or access point. (MoCa is fine).

      ​@Jvs1991, I don't have experience with Verizon routers. But if I understand correctly, you are using a wireless extender and a powerline adapter. Neither of these works well with Sonos.

      I'd recommend disconnecting the One SL from the MoCa powerline adapter and setting up a wired backhaul between the Verizon router and the Fios extender.

      MoCa is not Powerline: MoCa is a hardwired connection over coax and works very well. Powerline is garbage over power lines.

      Why would there be a problem then?

      Can you plug something else into the moca adapter to make sure you have a good ethernet connection at that point? If it is good, then I have to agree, the wifi extender is probably setting up a separate subnet.

      I’ve just looked through the manual for the Verizon CR1000B. Router/wifi. Includes ethernet LAN and coax moca connections. Very configurable. No mention of extenders, so if you have a wifi extender, what brand/model is it?

        It’s the Fios extender that is compatible with their router. CE1000 I believe

          Is this the range extender? It supports Wired Backhaul (i. e. Access Point mode)
