The short answer is no; you cannot connect to the internet using just a router. Below, we will explain why a router alone is insufficient and what additional components you need.
The Role of a Modem
To connect to the internet, you need a modem. This device is essential because it connects your router to your ISP’s network. Here’s how it works:
-
Modulation and Demodulation: A modem modulates digital signals from your router into an analog signal that can be transmitted over telephone or cable lines and vice versa.
-
Connection Point: The modem is often the first point of contact with your ISP. It connects directly to their infrastructure, fetching the data that your router will then distribute to your local network.
-
IP Address Assignment: The modem is usually assigned a public IP address from your ISP. This address allows your network to be recognized on the internet.
In the absence of a modem, a router will not have a method for accessing the internet, rendering it ineffective in establishing a connection.
Combining a Modem and a Router
In many cases, people use a modem-router combo unit, which integrates both devices into one. This setup simplifies the networking process and can save space. However, it is crucial to understand that even in this combined device, both functionalities still exist.

What is a router and how does it work?
A router is a networking device that forwards data packets between computer networks. It connects multiple devices within a local network and directs traffic to and from the internet. By assigning local IP addresses to each device and using a single public IP address through network address translation (NAT), the router enables communication among devices on the network and allows them to access the internet.
Routers also provide additional features such as firewall protection, which helps secure your home network from external threats. They can support both wired and wireless connections, allowing devices such as computers, smartphones, and smart home devices to connect conveniently and efficiently.
Can you connect to the internet using only a router?
In many cases, a router alone cannot connect you directly to the internet. A router needs a modem or an equivalent device to establish a connection with your Internet Service Provider (ISP).
