Open a web browser and go to mywifiext.net. Follow the on-screen instructions to select your home Wi-Fi network and enter the network password. Once connected, the extender will boost your Wi-Fi signal. For a more personalized setup, use the Netgear Nighthawk app. For help with the setup process, refer to the Netgear Wireless Extender Setup page or contact our technical experts via live chat for assistance.
