Understanding Modem and Router Basics
Before we dive into the troubleshooting process, it is essential to comprehend the roles of modems and routers in your home network. A modem (modulator-demodulator) is a device that connects your home to the internet via a physical connection, such as a coaxial cable or fiber-optic cable. Its primary function is to establish a link between your local network and the broader internet infrastructure. On the other hand, a router is responsible for managing data transmission within your local network, directing traffic between devices, and providing security measures to safeguard your network.
How Modems and Routers Communicate
The communication between a modem and a router occurs through a process called Dynamic Host Configuration Protocol (DHCP). When you connect your router to the modem, the router sends a request to the modem for an IP address. The modem then assigns an IP address to the router, allowing it to access the internet. This IP address is unique and serves as the identifier for your router on the internet. If the modem fails to recognize the router, this IP address assignment process is disrupted, resulting in connectivity issues.
