Modem vs. Router: Do I Need Both?
Want to get more out of your home internet?
When setting up the internet in your home, you'll often hear about modems and routers. Some people use these terms interchangeably, but that's not correct. They are two distinct devices with different functions.
A modem connects your home to the internet, while a router creates a network within your home, allowing multiple devices to connect. The question is: Do you need both?
In this article, we'll explain what modems and routers do, their differences, and how to choose the best setup for your home or office internet.
What is A Modem?
A modem is a hardware device that connects your home network to the internet through your Internet service provider (ISP). It translates the digital signals from your devices into analog signals that can travel over a coax cable, DSL, or fiber optic lines, and vice versa. . The most common types of modems are cable modems, DSL models and fiber optics modems.
In most cases, the Internet Service Provider (ISP) rents modems to their customers, which may include additional perks. With that said, purchasing your modem can save you money on monthly rental fees (up to $150 per year* depending on your current rental prices). A modem provides a wired Internet connection and if you have only one to connect to the Internet, such as a PC or laptop, a modem alone may suffice. However, if you have multiple devices or use the Internet wirelessly (WiFi), you'll need a router.
What is a Router?
A router is a device that distributes the internet connection to devices in your home. It creates a network that allows multiple devices to connect to the Internet at once.
Some routers, known as cable modem routers or gateways, combine modem and router functions in one device. However, if you prefer more control over the network settings and security, a separate modem and router may be the way to go.
When setting up your home network, you can buy your own router or rent one from your Internet Service Provider (ISP). Buying can help save you money in the long run, but renting from your ISP does have the benefit of access to technicians and assistants. Your choice depends on your needs for network control, budget, and technical expertise.
Do I Need Both a Modem and a Router?
A modem is required to connect to the Internet from your home or office. Your ISP sends you analog Internet signals, which a modem converts to digital signals. A router converts and sends these digital signals to your devices.
Modems typically have one LAN Ethernet connector, which you can connect to only one computer. It also does not provide the same level of protection as a router. If you want to use WiFi or connect multiple devices to the Internet, you need both a modem and a router.
Routers allow multiple devices to connect to the Internet and provide better network security. However, a router alone can not connect you to the Internet-it must be linked to a modem to distribute the Internet connection to your devices.
Some devices, called gateways, now combine modem and router functions. These eliminate the need for separate devices when setting up your home Internet connection.
How to Setup Your Internet for Best Performance
To get the most out of your home or office Internet setup, consider these steps:
- Place your router centrally: Position it in a central location of your home away from walls and metal objects. This helps distribute the WiFi signal more evenly throughout your space and improve coverage.
- Update firmware regularly: Keep your modem and router firmware up-to-date. If you purchased your own devices, check for new releases that can improve performance, apply bug fixes, and enhance security. If you are renting, your ISP can help you do it for you.
- Use the right frequency: Most new routers provide both 2.4GHz and 5GHz bands. The 5GHz band typically provides faster speeds but has a shorter range. Use 5GHz for devices close to the router and 2.4GHz for those farther away or separated by walls.
- Use a wired connection for stationary devices: For stationary devices like desktop computers or gaming consoles, use an Ethernet cable connection. Wired connections are faster and more stable than WiFi, which can significantly improve your experience for bandwidth-intensive activities like gaming.
For most households, having both a modem and a router is ideal for a fast, secure, and versatile home Internet. Ready to upgrade your home Internet experience? Check availability in your area to see what high-speed Internet options Optimum offers.
