What is the difference between a modem and a router? Routers and modems perform different functions. Using a modem, you can access the Internet. Using a router, your devices connect to your home network (a.k.a. Local Area Network or LAN) or Wi-Fi network, which then allows them to communicate wirelessly. Routers do not directly connect you to the Internet. Then, how do modems and routers interact? This article explains their differences.


You will need a router to connect multiple devices to the Internet, or to use them wirelessly (over Wi-Fi), as stated earlier. Your router enables your devices to communicate wirelessly with each other and connect to the Internet if you have a home network or Wi-Fi network.

What is the purpose of a router?

Using a router, you can connect wirelessly to the Internet at home or in other places. Without a router, you cannot create a wireless network. A router receives data from an ISP and translates it. Routers do not communicate directly with ISPs; this is what a modem does. Hence, a router serves as a necessary “middle man.” Routers receive data through modems, which are the devices that directly communicate with an ISP.

Using a router, you can communicate with your network devices through translated data. Think of a router as your household’s network hub. You can also use routers to manage Internet traffic for your devices. The reason your Internet slows down is if too many devices try to connect to it (by connecting to your router).

Routers are essential to you

If you want Wi-Fi in your home, you need a router. The modem you use for Internet access is your Internet service provider (ISP), but the router takes what the modem sends and translates it for your wireless devices. In other words, you are sending your devices a Wi-Fi signal.

 On a side note, if you have got your own router and are only looking for a reliable connection to make things thrive, Grande is a pretty decent option. It would not cost you much as the Grande internet plans are quite affordable. They also have no long-term contract so you can always quit if it does not fulfill your demands.

Let us now move towards modems. If routers still confuse you, your questions are always appreciated at the end of this article.


An ISP modem transmits digital signals from your ISP to your computer and translates them so it can understand them. A modem typically has two connection ports: one for a connection to your ISP, and one for a connection to your computer/laptop or router.

You can choose from analog modems (dial-up), DSL (digital subscriber line) modems, or cable modems. Cable modems should be used with Cable Internet service providers (ISPs). These devices allow you to access the Internet.

Modems are typically provided by Internet Service Providers (ISPs) with a monthly rental fee, and oftentimes, that fee includes support and troubleshooting. It is possible to save up to $168 per year* by buying or renting your own modem (depending on your rental fee at the moment). Modems offer a reliable, wired connection to the Internet. If you intend to connect multiple devices (wireless) or connect multiple devices simultaneously, you will need both a modem and a router.

Types of Modems

A modem can be a cable modem, digital subscriber line (DSL) modem, or a dial-up modem. Although each of them provides Internet access, their methods for connecting to and delivering it are different. Fiber technology is also available for Internet access, but a specific fiber modem is required. More on that later. Here are the different types of modems you must know about:

Cable modem

By using coaxial cables connected to the outlets in your wall or on your cable box, cable modems connect your devices to high-speed Internet. Your ISP sends data through a coaxial cable to a cable modem.

Cable modems are appropriate when: 

  • Your home has coaxial wiring. 
  • You need an Internet connection that is fast and reliable.

DSL modem & Dial-up modem

Dial-up and DSL modems connect to your phone line using a cable. In contrast to dial-up modems, DSL allows you to connect to the Internet and use your landline phone.

DSL is preferable when:

  • Speed is not a concern.
  • Cable wiring is not present in your home.
  • You only have a DSL or dial-up connection with your ISP.

Fiber technology

Fiber Internet offers a much faster connection than others but requires expensive wiring and updated devices. Fiber Internet is also known as “fiber optic Internet,” “fiber Internet,” or “fiber.”

Use fiber when:

  • If you are setting up Internet in an office or a large space, it will be more expensive than at home.
  • High-speed Internet is essential.
  • Security is paramount.
  • Installation is within your reach.

Your choice of modem and configuration is ultimately determined by your situation and preferences. No matter what the situation is, there is always a better way to solve it.


Understanding the difference between routers and modems can get a little confusing sometimes. That is why we came up with detailed information about their functions and differences in this article. We hope most of the confusion is cleared up. If you still have questions and queries, please drop them down in the comments section below. We will get back to you soon.
