Open a web browser and enter your router’s gateway IP address (commonly 192.168.1.1 or 192.168.0.1). After logging in, navigate to the wireless settings section, which typically displays your WiFi name and password. If you are unable to retrieve it, resetting the router to factory settings will allow you to set a new password, but be aware that all personalized settings will be lost.
