If you need the exact steps for your specific router brand, provide the model number (e.g., Motorola MB7420, Arris SB6183), and I can give more precise instructions.
Open a web browser on a device connected to your network and type the router's IP address in the address bar. Common IP addresses include 192.168.0.1 , 192.168.1.1 , or sometimes 192.168.1.100 . If you're unsure, check the underside of your router or the documentation that came with it.
