Sonos play 1 not connecting to new mesh wifi network

Good afternoon all,

I’m after some help/advice please, to enable my 2 Sonos play 1 speakers to work wirelessly on my new wifi network. I’ve followed numerous help articles online, but without success, hence this post.

Situation:

I’ve recently introduced a new mesh wifi system to my home to increase WiFi coverage. (this has included introducing a new mesh hub, which is plugged into the existing router via an ethernet cable)

Challenge:

Despite numerous steps (see below), I have been unable to get by play speakers to work on the new network wirelessly. FYI the speakers will work when connected via ethernet cable to the new mesh hub, but this is not a viable solution moving forward.

Steps taken so far (following advice in the app and help articles):

  • Removed the 2 speakers from the app (so that no products show in the Sonos app when it re-loads)
  • Factory re-set the speakers (however they do not display a green light when powered - instead the light goes solid white after flashing white and orange)
  • Deleted the old wifi network in the sonos app (this has stopped the speakers trying to re-connect to the old network)
  • Closed and re-launched the sonos app (which fails to find the new speakers and then suggests a factory re-set, hence back round the same unfruitful steps above)
  • Connected speakers via ethernet cable, which works - but speakers do not migrate to wireless set up when ethernet cable removed (app still fails to find the products)

Any tips/help appreciated please

Thanks

From what you say, the factory reset process is not completing successfully.

If you only have the two speakers, I would connect one of them to your router by Ethernet, then factory reset the other. This will ensure playlists and music services etc are transferred to the reset device, otherwise, you will lose all data.

When you factory reset the other device, do not have that one connected by Ethernet. Unplug from power, then reconnect power whilst holding the play/pause button until the led starts flashing white/orange. The LED needs to flash green for the factory reset to be successful.

If the device does not flash green, then I’d contact Sonos Support as to why you are unable to factory reset the device.

However, if it does flash green, then you can add to the system, inputting the new WiFi credentials during the setup process. After you have added this device, you can then disconnect the Ethernet cable from the other device and factory reset that one. Following the same process.

​@Mr. T, ​@AjTrek1, ​@Pools-3015 and ​@AjTrek1 thank you for all your tips - finally have reached a resolution. Combination of disabling old wifi, putting mesh into access point mode and contacting Sonos support for factory re-set of both products has resolved the issue. Great to see the power of the Sonos community in resolving issues.

I have more than 20 Sonos speakers and many other devices in my LAN, either wired o Wifi.
In my Sonos system, I was having problems streaming music from Spotify, Apple Music and others; also it was almost impossible to listen to any Sonos Radio. Starting a list from Spotify was very slow and not reliable. Slow list loadings or with errors (10001, 1002...); and speakers grouping were also common problems.


After many interactions with support people, we stated that there were no problems with Sonos ecosystem.
Then, I realized I was the problem after installing a TPLINK mesh Deco. 
Skipping the -very long- resolution process, the final configuration that is working fine and smooth is:

  1. Internet provider-->Modem (passthrough)→ Deco Router-->Other Deco Mesh devices-->Sonos and other devices.
    Important Note (added by Sonos Support): Cable just one (no more) Sonos speaker to the router. In this way, Sonos will use Sonosnet for Sonos traffic.
    If you cannot wire one speaker to the router, Sonos will use your wifi in full.
  1. If case you cannot switch the modem provided by your Internet company, another possible conf is:
    Internet provider-->Modem (ROUTER (default))→ Deco (Access Point)-->Other Deco Mesh devices -->Sonos and other devices.
    Important Note (added by Sonos Support): Cable just one (no more) Sonos speaker to the router. In this way, Sonos will use Sonosnet for Sonos traffic.
    If you cannot wire one speaker to the router, Sonos will use your wifi in full.

After making all the changes, I re started all the Decos and internet modem and after tested the Modem and the Deco were working fine, I turned off not only the Decos again, but also I turn off the full house (main electricity breaker), waited 20 seconds or more, and then re-energized everything. This forced all the devices -Sonos speakers included- to ask for a fresh IP address).
All was working perfect and smooth!
Then, I stressed the Sonos system with all the previously not working functions and everything was and are working smooth and really fast!

(After a couple of hours I reinitiated by its app, all the Deco System, and the Internet speed measured at DECO level improved a lot, about 70%. I don’t know why.)

I assume this configuration could work in other mesh systems, but I didn’t tested.

Hope it helps!

Side note: To explore the Sonos environment, I recommend the use of the following URL, from your LAN: http://aa.bb.cc.dd:1400/support/review, where aa.bb.cc.dd is the local ip address of any of yours Sonos speakers.  (Thanks, BSteiner!!: “The last line, “Network Matrix” is the grand prize for Sonos diagnostics.).
Don’t spend time understanding the network matrix created: Copy-paste the image to your favorite AI app (in my case Gemini) and it will be interpreted for you. The recommendations provided were really useful.

​@CEJL 

Great you resolved your issue.

It appears you placed your ISP router/modem combo into Bridge mode for the router side. Then connected your Deco to the ISP modem. Although you seem to have offered two solutions I'm not completely sure of my analysis of your post. What I am sure of is that you previously had two Wi-Fi networks in play which caused the problems.

Keep in mind the Network Matrix is a legacy page and newer Sonos aren't fully supported. Still it is interesting to look at and I'd love to see an updated version that supported all Sonos devices.
