To set up a Netgear Wi-Fi extender, first plug the extender into an electrical outlet near your router. Wait for the power LED to turn green. Next, connect to the extender's Wi-Fi network using your smartphone or computer. Open a web browser and enter www.mywifiext.net to access the setup page. Follow the on-screen instructions to select your existing Wi-Fi network and enter the password. Once connected, the extender will reboot, and the connection will be established. For optimal placement, move the extender halfway between your router and the area with weak Wi-Fi signals. This completes the Netgear WiFi Extender Setup.
