Modem vs Router: Which one do I need?

You might think the two terms describe the same thing, but modems and routers are actually different. Today, however, they’re often used so interchangeably that they almost do mean the same thing – that little box you access the Wi-Fi through, and in fact, most modems today are modem routers, a mix of the two. But what are the differences between modems and routers, and which is best for your home internet needs?

What’s the difference between modems and routers?

Routers connect your devices around the home to each other, while your modem connects to the wider internet, allowing you to access websites like Google and Facebook. When you connect to Wi-Fi, you’re connecting to the router part of your box, which then forwards traffic through the modem component and the internet. These terms are often used interchangeably, but in reality, they are very different.

  • If you need Wi-Fi connection for multiple devices, a router with a built-in modem is what you’ll need. This is very commonplace in modem-routers, and likely what you use today.
  • If you have a modem-only device, it is usually wired and you’ll need to connect directly to it to access the internet. To get multiple devices connected, you’d need to buy a router and plug it into the modem.
  • Note that these devices are separate from your NBN connection box, seen in FTTP, FTTC and HFC connections.

Luckily, we’re not living in 2001 anymore; providers and retailers these days offer hybrid modem-routers. This means that you simply need to ‘plug and play’ without fiddling with two devices. You’ll only need to get into the back end of the one device through a setup portal. You can also buy these modem-router hybrids separately to couple with BYO plans. Setting up a modem is easy too.

Most devices on the market today may say they are a ‘modem’ or a ‘router’. However, the fact is the device you are purchasing probably includes both. Typically, if what you’re buying really is one or the other, it should specify this. If you want to be extra careful, look out for an ‘NBN ready’ sticker or badge on the box, just to be sure. Your current router might even be NBN ready.

What is a modem?

Modems are devices that connect your home to the internet. Essentially, modems receive internet data through the wiring in your home (either through fibre wiring, copper wiring, signal towers or satellite signals in Australia) and translate internet data for use in your home (this data is then sent to your router). Think of it like a junction where the internet meets your home and sends data between the larger internet and your WiFi.

Modems connect via an ethernet cord or coaxial cable to your internet supplying wall socket, depending on the type of technology your home uses. Some NBN technologies (such as FTTP and HFC) use an additional box that then speaks to your modem and router. Modems then communicate with your router via an ethernet cord, unless you’re using a modem-router hybrid.

These days, standalone modems are more difficult to come by than modem-router hybrids, which you likely own. Having modems and routers as separate devices is an unnecessary hassle these days, so having them combined into a single device solves a lot of problems.

How much do modems cost?

Modems can cost anything between $50 and $700, depending on the features you want included, the brand, and ultimately if you want it to be a modem-router or not. Of course standalone modems are generally cheaper than modem-routers, but they’re more technical, and you’ll end up spending an identical amount on a router anyway.

What is a router?

A router is a device that transmits data throughout your home, through either wired (via ethernet) or wireless (via WiFi) connections. Routers are the local point in your home connection and connect to your computers, laptops, TVs, gaming consoles and phones, allowing them to access the internet.

Your router connects to the internet by speaking to your modem, which speaks to the internet. If you have both devices separate, the modem connects to your router through an ethernet cable, which is plugged into the WAN (Wide Area Network) port. If you’re using a modem-router hybrid, you simply subvert the role of the modem as a separate device, and plug the WAN ethernet cord into the connection box or your wall port, respective of what NBN technology your home is serviced by.

It’s quite uncommon that you’ll come across anyone using a separate modem and router internet connection, as most modems and routers sold by retailers these days are hybrid modem-routers, meaning they do two jobs in one. That being said it’s important to know the difference.

How much do routers cost?

Routers will set you back typically between $50 and $700, depending on the type of router you get, the features it’s capable of, and ultimately if it’s a standalone router or a modem-router hybrid. Standalone routers are typically cheaper, although you’ll end up spending the same amount of money when you pick up a standalone modem.

How do modems-routers work?

Sometimes referred to as a ‘Gateway’ Modem-routers connect to your home internet connection type, which speaks to the rest of the world wide web. Often today, modem-routers are sold as hybrids, capable of both the role of the modem and the router, whereas in previous decades they would have been separate products.

LED lights on the modem, router or modem-router indicate the status of your home internet connection, including if the devices are being powered, if the router is transmitting data over LAN or WiFi, or if the modem is receiving data from the internet. Typically, these lights can help you find out why your internet is slow, but that often requires some deeper investigation.

Some modem-routers are capable of 4G as a backup connection or are built to use 4G or 5G signals. Depending on what your plan is or which provider you’re using, you might not have access to this, but it’s worth checking. For 4G or 5G only internet, consider picking up mobile broadband or home wireless broadband.

What should I get – modem or router?

If you’re in an electronics store scratching your head and the assistant comes over and you say either modem or router, they’ll likely refer you to the same thing. Because these days the terms are used pretty much interchangeably, and often both the modem and router come in one neat package. Today you can’t really go wrong, but if you have a modem only, you will need a router as well.

  • A modem-router today can cost upwards of $700, or as little as $40-$50, but many brands include both components.

Alternatively, going with a provider with an included modem can take a lot of hassle out of the equation. Though if you’re a discerning buyer, going your own way may be more satisfactory. Remember – routers ‘route’ the Wi-Fi network around your home, and modems connect you straight to the internet. Happy shopping!
