The Nokia WiFi Gateway 3 allows you to set up a fiber-based network in your home.
The Gateway 3 must be installed by a representative from your internet service provider.
You can use the Nokia WiFi 3 with the Nokia WiFi mobile app to manage your network and add Beacons to extend your network.
See "setting up your Nokia WiFi" to learn how to setup with the mobile app.
Note: You only need a Nokia Gateway 3 if you want fiber connectivity around your home. Nokia WiFi networks work just fine with only WiFi Beacons.
