Modem vs. router: What’s the difference?

If you’ve ever had to try to troubleshoot a slow internet connection or setup a home network, you might have wondered: what is the difference between a modem and a router? The two black boxes that connect you to your favorite streaming services and laptop and phone to the rest of the world do a lot of work, but ideally you don’t have to fuss with them much. That said, it can be useful to know what the difference is between a modem and a router. As a bonus we’ll also cover what a gateway device is–stick with us.

What’s a modem?

A modem acts as your direct line to the internet and it actually stands for modulator-demodulator (did Dr. Seuss come up with this name?). In basic terms, modems act as a translator of signals that allow your home network to connect to the internet through your ISP (internet service provider).

If we’re getting too into the weeds, think of it like this: your modem provides the crucial link between your computer (or phone) and the World Wide Web. Without a modem, your computer is just a sophisticated brick. Modems enable computers, and all your other devices, to communicate with other computers across the globe.

What’s a router?

A router is an electronic device and your modem’s best bud (and probably your household’s best bud too). While a modem might be responsible for connecting you to the World Wide Web, routers function as a broadcaster to a Wi-Fi network, organizing  data coming in from your modem and routing (get it?) it to the right destination in your local network. 

Routers are responsible for creating your Wi-Fi coverage, allowing for multiple devices to connect, as well as firewall protection and port forwarding for the gamers reading this. Routers come in a variety of sizes, from small plug-ins to large wall-mounted modes for better signal strength.

What are the main differences between modems and routers?

The main difference between modems and routers is that your modem provides direct access to the internet. In earlier years of the internet age, you would have to connect an Ethernet cable to your computer to provide a hardwired connection. Luckily with a router we don’t have to do that anymore, because routers provide a Wi-Fi network for a whole household of devices to connect to (along with the opportunity for fun Wi-Fi network names) . So you can thank routers for enabling you to binge your favorite show from anywhere in the house. 

Without a modem and a router, you wouldn’t be able to access your favorite websites, streaming and social platforms or share that connection with your other devices. Routers can also provide additional security measures like firewalls, protecting your data from sketchy activity when browsing online or downloading files from emails. Routers also enable filtrations like parental controls, keeping younger internet users safe.

So, now that you know the differences between a modem and a router’s technical functions, you’re ready to learn what a gateway is. A gateway is a network device that has both a modem and router built into one, and makes home internet installation super simple. Some cool companies (cough Mint cough), offer gateway devices with their home internet plans that you can plug-in for nearly instant internet connection. We’ll get more into that below.

Do I need both a modem and a router?

Yes and no. A modem can provide direct access to the internet on its own but for a household to connect multiple devices, you do need a router to broadcast your Wi-Fi network. 

All households that need wireless internet (aka basically everyone) need a connection to the web (that’s where the modem comes in) and wireless access to connect their devices to (that’s you, router). As we said above, with the introduction of gateway devices, you can get an all-in-one solution that provides both, making quick internet setup possible with one device. 

Speaking of gateways, if you’re considering a new home internet provider, our 5G Home MINTernet plans include a free 5G gateway device, making home internet improvemints a cinch with DIY setup in minutes. Shameless plug: done.
