Whole sonos system reverted to old Wifi network.

3 months ago, we got Starlink. I migrated all of my Sonos and Airplay devices to the new wifi (different router, different SSID). Since we had prepaid for the other ISP we retained that router and wifi network. Everything has worked perfectly for 3 months. Then, suddenly about 2 hours ago, every sonos device switched back to the old wifi network. The other Airplay devices are still on Starlink and the Starlink connection is working fine. It’s kind of a pain to move each device back one by one any advice on how to move them back and keep them there?

Odd. I wonder how they ‘remembered’ the old network data.

In any case, I’d follow the instructions in the new router - installation instructions FAQ.

True, somewhat, although this is not just a Sonosnet issue. If it was then it wouldn't cause spanning tree on the lan WHEN THE WIFI ENABLE/DISABLE SETTING RANDOMLY REVERTS TO ENABLED which is not something I can advise on how to replicate but assuming Sonos has a lab with hundreds of devices and people paid to use it, they would be able to catch it.

This is surely all to do with SonosNet. The “WiFi” enable/disable switch has nothing to do with WiFi at all. It enables/disables SonosNet wireless on the device.

If the setting is somehow re-enabled then it’ll (re-)establish SonosNet wireless pathways that could potential cause loops or, in the case of an STP/RSTP battle, bridge wirelessly (and slowly) across the wired backbone.

FWIW in 16 years I don’t think I’ve ever seen a device take it upon itself to re-enable its radio in normal operation.

At the point when it’s actually being disabled via the controller it may revert within a minute or two if it decides there’s no satisfactory network pathway back to the controller. This is a safety precaution to avoid a device marooning itself. Also, the device will want to see a direct wired path back to the STP root bridge, rather than be daisy-chained.

Of course if the device is put through a factory reset it will also re-enable its radio.

Welp that's odd, since as I have now removed the Home WiFi said and logging from Sonos, in addition to the per device level disabling of WiFi, they have not reverted to Wi-Fi enabled.

Which means no portable speakers for these owners.... Fine by me. So long as the Sonos stack doesn't kamikaze the network anymore.

Just had the same problem. I recently moved my whole house to a new ubiquiti router. After a month my playbar suddenly just jumped back on to the old network. I don’t know how considering it was reset and that network was not in the list of known networks. Where are these being stored?

This data is stored on each speaker, and not in the controller.

We've had several more systems go down over the past few months. I'm over it. Blue sound is better quality and I can stand to do without the problems..

In my installation the SONOS units have choice of two WiFi networks. One is a mesh and one is the ISP’s Gateway. Both are on the same subnet. When I check the players, in some cases the SONOS system will be split between the two networks, in other checks it will be all one or the other. The controllers can also flip between networks. During a WiFi hardware update the updating WiFi will shut down and the SONOS units will flip to the other network. I deliberately setup to allow this WiFi choice.

Typically, when adding a mesh or replacing the Gateway you’ll end up with separate WiFi networks. You must make sure that SONOS and the controllers are always on the same subnet and that there is only one router. Check to make sure that the unwanted network is not listed. Also make sure that your controllers are not using the wrong access point. In addition to the two home networks, I have an office network defined here too because I may occasionally take a unit to work. The traveling unit will seamlessly connect at work.
