Is it better to use a gateway or a separate modem and router?

Getting your home network set up sounds easy in theory, but it’s also easy to get confused. Sometimes it seems like you need a glossary to be able to understand what should be basic instructions. 

Of those terms, we come across gateways, modems and routers. You know you need these pieces of hardware to connect to the internet — but you’re not exactly sure why or which option is best for you. 

We’ll take a look at what a gateway is, how it’s different from a modem or router, and whether it’s better to use a separate modem and router or a combined gateway. 

What is a modem?

A modem, or modulator-demodulator, is a physical device that connects a device to the internet via a broadband connection. It receives signals from the internet service provider (ISP) and sends them to the device. A modem can only connect to one device at a time — in many cases, this is the router. 

What is a router?

A router is a physical device that connects the modem to all of the network-connected devices like computers, phones, smart TVs and home cameras. Sometimes routers connect via a cable to the modem, while others are completely wireless — most, however, offer both options. 

What is a gateway?

A gateway is a router-modem combo, sometimes called a gateway router or a gateway modem (or even gateway modem router). Essentially, it combines the two in a single physical piece of hardware. This consolidates your technology so it takes up less space and requires fewer messy cables. Many ISPs offer new customers the option to lease or buy a gateway directly from them at signup. 

Gateway vs. router and modem

The main difference between a router and gateway and a gateway vs. modem is what you can physically see: Instead of requiring two boxes to set up a home network, you only need one when you use a gateway. Using separate devices or a single gateway each comes with its own set of pros and cons.

Overall, the pros typically outweigh the cons when separating your modem and router. You have more customization options and flexibility. However, if it’s convenience you’re after, you can opt for a gateway from your ISP.
