The Linksys Extender RE6400 setup process helps you boost your existing Wi-Fi signal to reach dead zones and improve coverage throughout your home or office. To get started, plug your RE6400 into a power outlet within range of your main Wi-Fi network and wait for the LED lights to stabilize. Connect a computer or mobile device to the extender’s network, then open a web browser and navigate to the setup page to begin configuration. Once there, choose your primary Wi-Fi network, enter its password, and complete the steps to link the extender to your router. After setup, the RE6400 will extend your wireless signal, providing a stronger and more reliable connection in areas that previously had weak coverage.
