Open a web browser on your device and enter "routerlogin.net" in the address bar. Log in with the default username and password (admin/password). Follow the on-screen instructions to configure your Wi-Fi settings, including network name (SSID) and password. Ensure your router firmware is up-to-date for optimal performance.
