Bad Sonos connection, what to do?

Hello,

I live in a 2-floor house (ground level and 1st floor), which has 500 Mb/s internet connection. I use a TP-link Mesh wifi setup to distribute internet: 3x Deco M9plus (one is the main Deco attached to my modem) + 2x Deco M5. All Decos are connected by Ethernet cable to the first Deco router using a switch (star network). I am on S2.

In my living room (ground level), there are 1x Connect GEN2 (connected to my HiFi system’s DAC) and 1x Sonos Amp (using 2x Sonos InCeiling speakers) + 1x Sonos Sub GEN2 + 2x One SL’s as surround (previously I had 2x Play 3s working flawlessly). All of these were connected via Ethernet cables except the One SLs (Amp+Connect+Sub are connected via Ethernet cable to the main Deco M0Plus). In this living room, there is also a second Deco M9plus using a ethernet backhaul. In the same level, I have another room where there is a 1x PlayBar (in this room there is also a Deco M5 using also Ethernet cable backhaul) connected via Ethernet cable to the Deco M5.

In the 1st floor, there is a Deco M9plus attached with ethernet backhaul where there are 3 rooms (in my bedroom has also a Deco M5, ethernet backhaul). In this room, I have a Sonos Boost connected to the Deco M5 via Ethernet cable, and there are 2x Symfonisk bookshelves paired, and connected via Sonos Net via the Boost.

Everywhere in the house, I have at least 200-250 Mb/s wifi speed.

Sonos setup is with Sonos Net (WM 0).

Everything was working OK until now. When I changed the Play 3s (surrounds via wifi Sonos Net), and when I made the setup for Sonos Onel SLs as surround, everything worked nicely. However, since a couple of days, the 2x Symfonisks and the 2x One SLs were not working.

This morning, I made a modem reset, reset of all switches and all Decos. The unplugged all Sonos material. Replug the Sonos system. In the beginning everything worked (Symfonisks, and all the other Sonos connected via ethernet cables, except the One SLs (the system does not see them)). I passed a couple of hours without success (when I unplugged the One SLs and replugged I did undo the surround setup, and they worked. But when I tried to do surround setup, the system lost them). Then, as there was another Deco M9Plus near the One SLs, I put another switch to the Deco and plugged the One SLs via ethernet cables. Now everything works normally but I would not like to have this switch and cables near my One SLs...

Could you help me?

Thank you Ratty.

Sonos AMP, Sub, Connect GEN2 are wired to the primary mesh via 2 switches; one just beside the main Deco, which wires all the other Decos and the 2nd switch beside the Sonos AMP (where the other Sonos and my TEAC NT-505 streamer are wired). 

The One SLs are (now) wired to a 2nd Deco via another switch.

The Playbar is wired to another 2nd Deco via another switch in the same room as Playbar.

The Symfonisks (L+R) upstairs are connected to the Sonos Boost via Sonosnet wifi, which is wired to another 2nd Deco (same room as the Boost and Symfonisks).

Just an information: since longtime (2 years?) the 2x Play 3s (as surrounds) were working without any problem, and One SLs, which replaced the Play 3s, worked without any problem ca. 5-6 weeks...

Sorry but I don't think my brain is up to taking that all in  but I will just say that if you have any surround speakers connected by Ethernet you should remove those cables, especially if the main HT device is wireless.

If you have set any of your wired devices to have 'WiFi disabled', please re-enable that setting.

    Hi John B,

    Thanks for the reply.

    In summary, Sonos Amp does not see the One SLs when I try to make a surround setup.

    Individually, if there is no surround setup, they work (Sonos App sees them). When trying to do a surround setup, they got lost…

    When putting One SLs also on ethernet, everything works.

    WiFi is not disabled…

    Could you be a bit more precise about what this means please?

    Normally, when you buy the 2x One SL, and include to your system, they become first individual speakers. 

    Then, you have 3 options: 1) use them individually in separate rooms, 2) create a stereo setup (LR), or use them as surround speakers with Sonos Amp (Dolby 4.1 in Sonos).

    When I try to attach them to Sonos Amp without ethernet cables, the App cannot finish the setup, and they disappear from the App’s menu.

    If I attach them via ethernet cables, it works…

    Previously, I had Play 3s, and used them without any problem with Sonos Net wifi. I changed them to Sonos One SL (bought on February), they worked also for a while but today I could not do the surround setup without ethernet cable attachment.

    Also, do you have wireless enabled on both the TP-Link and Deco?

    TPlink Decos are my WiFi Mesh system. They work without any problem

    As this has arisen 'overnight' and worked previously it may be a hardware fault. It would be worth submitting a system diagnostic after this has happened, and contact Support with the confirmation number. 

    Or it might just be a temporary glitch, in which case you might want to power everything off and on again.

      Just to add a bit of color, and hopefully not confusion, surround speakers and Subs in a home theater room do not connect to the standard ‘SonosNet’ signal. When in the home theater configuration, they use a separate 5Ghz channel to connect to the ‘root’ of the home theater ‘room’, which, if I can understand the original post, is an Amp in this case. But it would be the same with a Sonos soundbar too. So additional sources of interference could be affecting the connection of your surrounds to the ‘front device’ of your Sonos home theater setup. 
       

      Back to @John B ’s excellent assistance…..

        I would call them, or perhaps chat online, once you have the diagnostic reference. You might also want to consider toggling ‘OFF’ the WiFi on the Amp and then try toggling it back ‘ON’ to make sure it is definitely working, as that is used to communicate wirelessly (over a 5Ghz Ad-hoc connection) with the two surrounds (ideally).
