The Linksys WiFi range extender setup process is designed to boost your home WiFi coverage by connecting the extender to your existing network. First, plug the device into a power outlet and allow it to start up. Connect your computer or smartphone to the extender’s default WiFi. Then, access the setup interface in your browser to begin the guided installation. You’ll choose your main WiFi network and enter the password to sync both devices. Once the setup is complete, relocate the extender to an area between the router and the spot with weak WiFi to maximize coverage.
