Accessing Router Settings

You need to log into your router's web interface, usually accessible via a web browser at an IP address like 192.168.1.1 or 192.168.0.1. The exact address can vary by router model.

Configuring DHCP Settings

Locate the DHCP settings section in your router's interface. Here, you can assign a static IP address to a specific device by entering its MAC address.
