Make sure that you are placing the Sonos speaker within the network range of the router. Switch on the speaker.
Next, you need to download the compatible application for the Sonos speaker on your computer, smartphones, etc.
Explore the application and opt for the option named ‘Set up a new Sonos system’. Press the Standard Setup option. Then you have to choose the speaker model.
The app will guide you through some instructions. Act accordingly to the instructions. Afterwards, give your Sonos speaker a name.
If you have to set up multiple Sonos speakers to the router then repeat all the above steps. But before that, you have to head towards the Add Another Player option.
