How do you I access my router settings?

Hello,
Type ipconfig in the command prompt and press Enter to run the command. Scroll until you see a setting for Default Gateway under Ethernet or Wi-Fi. That's your router, and the number next to it is your router's IP address. Now type your router's IP address in your browser's address field and press Enter.
Thanks.
