Why Some Routers Have Two Networks (And What They Mean)




You may notice that your Wi-Fi router comes with two network options: 2.4 GHz and 5 GHz. This is a feature offered by most modern routers and known as dual-band networking. Called frequency bands, they both allow devices including phones, TVs, game consoles and computers to connect to the Internet via Wi-Fi. The difference is in the range and speed between the two bands.

The 2.4 GHz frequency band can go further, while a 5 GHz network has a shorter range. The lower band is best used for connecting devices that may be located in another room or that don’t require faster speeds. On the other hand, 5GHz is faster and provides increased speed for devices, although it does not increase the internet speed of your plan.

Most newer routers will have dual-band networks, allowing you to connect to either one. The main difference is that only certain devices can connect to individual networks. The router can be configured to differentiate between the two bands, so you know which network is available when it’s time to connect to Wi-Fi. Both can be named however you like, but to know which band is 2.4GHz and 5GHz, having the band in the name is helpful. While you’re adjusting these names in the router settings, you can tell your router to do a few other cool things.

What is the difference between 2.4 GHz and 5 GHz

As their names imply, a 2.4 GHz band is not as powerful as a 5 GHz network. However, it’s not that simple: one is better than the other. They both allow your devices to connect to Wi-Fi, but not everyone with Internet access in your home can connect to a 5GHz band. While almost anything that can connect to the internet can connect to a 2.4GHz network, you may find that a device like your TV or Xbox Series X/S works best on the 5GHz band.

The location of the router will impact what can connect to it. The 2.4 GHz band includes an extended coverage range, which means the service will work over a wider area. It is also less likely to be blocked by walls that could reduce its signal strength. On the other hand, the 5GHz band offers a more powerful connection, although the downside is that it doesn’t cover as wide an area. Any device you want to connect will need to be closer to the router.

One thing to keep in mind is the devices you want to connect to the router. Some, especially newer ones designed to handle faster speeds, may be better off connecting to the 5GHz network. These range from gaming consoles, TVs, and devices that you’re more likely to stream, play games, or spend most of your time with. If you only have a 2.4GHz router, you may need to upgrade to get the best possible result.

Do I need both networks in my home?

Today, it’s likely that you have multiple devices in your home using the Internet. The average home router can connect to dozens of devices at once, but connect too many and you’ll clog up the system, causing potential slowdowns. Connecting a TV, smartphone, and laptop for occasional watching and browsing may not require a 5GHz network, while streaming 4K movies and video games works best with a 5GHz network.

Likewise, a 2.4 GHz frequency band is a good option if you don’t have many devices connected to the network. If you plan to load your home network with many devices, you may want to move some of the more powerful ones to the 5GHz band. Using the lower frequency band is also better for devices that are a few years old. Many older devices may not be able to connect to a 5GHz band anyway. You can also settle for the lower option if the space you’re working with is a bit larger, as the 5GHz network works better with a smaller footprint.

It all depends on the number of devices you have connected, their nature and their location. If you’re focused on streaming or gaming, 5GHz is the better option, while 2.4GHz is designed to handle older devices or ones you won’t demand much from. However, if you buy a new router, it will most likely have a dual-band network giving you a choice between one or the other.
