Hi @Corina9091
Welcome to the Sonos Community!
I recommend that you reboot your WiFi router by powering-off for at least 30 seconds. Once you turn it back on, there will be a few minutes’ wait before you can try again.
If this doesn’t help, please make sure you are connected to the correct WiFi (not a guest WiFi) on your phone. If you have another, please also try from another phone.
If you have any WiFi boosters or extenders, I recommend you switch them off - at least for as long as it takes to get Google Assistant working.
If this doesn’t help, I recommend you get in touch with our technical support team, who have tools at their disposal that will allow them to give you advice specific to your Sonos system.
Hi Corry,
Thanks, I will go to try this.
Regards, Corina
