4. Power On and Launch App: Power on your modem. Once the modem is fully online, power on the main Deco unit. Open the Deco app on your mobile device and follow the on-screen instructions to complete the setup. The app will guide you through creating your Wi-Fi network name and password.
5. Place Additional Deco Units: Once the main unit is configured, place the remaining Deco units in strategic locations throughout your home to extend Wi-Fi coverage. These units will automatically connect to the main Deco unit and form a seamless mesh network. For optimal coverage, place them in areas experiencing weak signals, such as basements or outdoor areas like a back deck, ensuring they are within range of another Deco unit.
