Wifi change, cannot reconnect sonos system

Hi all,

yesterday I’ve changed my wifi (router and internet provider) at home.

If I open the sonos app from my phone the “System” voice is greyed out (see image below, sorry for the italian).

The alert I see (“impossibile trovare il Sonos System”) does not fix the problem: it can find my sonos device, I push the back button but the it can’t find the device.

Another problem is that I have the old wifi but without internet adn if I try to connect my phone to the old wifi I can select “System” and try to change the wifi connection of my Sonos envirorment but the procedure stops when the app checks it the the app itself is updated. This is frustrating.

I’ve also tried to reset the Sonos One device: 1. unplug the power; 2. press the back button; 3. keep pressing the back button while plugging the power. Nothing.

Any suggestion?

can you please help me?
