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 vs. 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.
Separate modem and router
More settings and customization options
Easier to upgrade your home network
More affordable to replace when no longer usable
Improved security features (WPA3 encryption, firewalls, VPN)
Two pieces of hardware can be bulky and take up a lot of space
Requires multiple outlets and lots of cables and wires
More involved setup and installation process
Requires less space, a single outlet and has fewer messy cables
Streamlined troubleshooting with a single company, instead of ping-ponging between two
Simpler and easier setup
Typically comes from your ISP, so it will include customer support
Difficult to upgrade
Difficult to diagnose and repair
More costly to replace than an individual modem or router
Comparatively limited security features
Is it better to use a separate modem & router?
Overall, the pros typically outweigh the cons when it comes to 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.
Moving forward with your home network
It’s critical to ensure your home network has the right speeds and security measures in place to serve you and your family. Keep connected with our Resource Center for more information about how to make the most of Wi-Fi at home.
