I have two ISPs and a separate WiFi network for each. I experienced reliability problems with my older ISP yesterday, so I attempted to move all of my Sonos speakers to the newer ISP/network. Went fine, except for my oldest Sonos One, which required a factory reset.
I did the factory reset, it appeared on the Sonos app, but no sound played, and it disappeared from the app after 60 seconds. Did this several times with the same result.
So I asked Anthropic’s Claude about this and it suggested I shut off my older network while adding the speaker to my new network. It worked!
But I woke up this morning and two of my speakers were missing in the app. I switched to my older network and there they were. So somehow two of the speakers reverted to the older network. In this case I tried Sonos’ AI chatbot. It had me do a few things that were not useful, but eventually suggested I remove my older network from the Sonos app’s memory - a feature I was not aware of. And that solved the problem.
So, if moving your speakers from one WiFi network to another, with both active, make sure to remove the older network from the Network settings in the Sonos app.
