What is WiFi?

WiFi is a wireless network that uses radio waves to transmit information from one device to another. But between adapters, modems, routers, and extenders, the world of WiFi can be a busy place. Let’s start with the basics to help you understand how WiFi works and how it keeps you connected.


A wireless adapter translates data from the device into a radio signal and transmits it wirelessly to a router. Most devices have wireless adapters inside.


A wireless router receives the radio signal, decodes it, and sends the information to the internet using a physical, wired Ethernet connection through the modem.


The data goes through one of two frequencies: 2.4 GHz and 5 GHz. A larger frequency allows the data to travel faster and farther.


The router can also receive information from the internet, translate it to a radio signal, and send it to the wireless adapter in the device.

How it works

The steps it takes to create a WiFi network may sound familiar, as cell phones and walkie-talkies (remember those?) use the same radio-signal technology to transmit information across devices. The main difference between WiFi radio and cell phone signals is that WiFi radio signals travel through a much larger frequency, allowing for more information to be sent at once. A more significant frequency also allows for multiple devices to connect to one router without experiencing interference.

Although you can connect to a wireless connection just about anywhere, it’s both convenient and safe to have home WiFi instead. You no longer need to travel to your local coffee shop or airport to connect to a public internet network, which is often subject to hacking and identity theft. Instead, CenturyLink WiFi allows you to enjoy browsing through the internet in the comfort of your own home and your information stays secure.

How adaptors, gateways, and extenders work

It’s essential to understand the pieces of equipment that make WiFi work properly—a fast internet experience is at stake! Three pieces of hardware affect your WiFi connection—an adaptor, gateway (modem/router combo), and an extender. Let’s take a closer look at the equipment and how it works so you can optimize your home WiFi for the best speeds.


Almost every device that connects to the internet has a wireless network adapter. The adapter lets your computer communicate with a wireless network. If you happen to own one of the few devices that don’t have an adapter pre-installed, there are options available to purchase.

Gateways, AKA modem-router combos

Modems and routers were traditionally two separate pieces of hardware, but now they come as a single unit, reducing clutter on your shelf. If you need one when signing up to an ISP, CenturyLink offers a gateway rental for a low monthly fee, making sure you have the latest hardware for your setup.

The router creates your local area network and allows multiple devices to connect to it by both wired and WiFi connections.

The modem connects the router to your internet service provider’s network.


Also known as a booster, an extender is a smart idea for homes with a lot of walls in between rooms. As the name implies, this hardware extends the WiFi reach to more rooms in your house. It comes wireless or wired, though, for best results, a wired extender most effectively improves in-home WiFi performance.

How do I reset my modem?

If your WiFi is lagging or you're unable to connect to the internet, you can try resetting your modem with these steps:

  1. Find the reset button, usually located on the back of the modem.

  2. Using a pencil or pen tip, gently press the small button.

  3. Hold the reset button down until the red and green lights on the front of your modem start flashing.

  4. After five or so minutes, the “internet” button on the front of the modem should flash green.

  5. Try reconnecting to the internet on your phone or computer.

  6. Reenter any account information you're prompted to when you connect, such as the WiFi password.
