Nowadays, we hear the term “Wi-Fi” thrown around as if it’s been around forever. But what is Wi-Fi anyway? How does it differ from the internet? What part does it play in getting you connected? We’ll outline the basics you need to know and give some tips on how to maximize your home Wi-Fi performance.
What is Wi-Fi?
Believe it or not, Wi-Fi, or Wireless Fidelity, and the internet are not the same thing, although we often hear both terms thrown around in the same breath. Wi-Fi is actually the technology that allows your devices to wirelessly connect to the internet. It also allows internet-connected devices like smartphones, computers, tablets and smart home devices to exchange information with one another, essentially creating what is your home network.
How does Wi-Fi work?
To put it simply, Wi-Fi works by using radio frequencies to communicate back and forth with your devices. Your internet-connected devices each have wireless adaptors that translate necessary data into a radio signal. That signal is transmitted using an antenna. Your wireless router receives that signal and translates to the internet.
Your router will also receive information from the internet (movies, music, files) and communicate it as a radio signal back to your devices. Wi-Fi transmits data on the frequencies of 2.4GHz and 5GHz — you’ve probably heard of these numbers as channels on your Wi-Fi network. These frequencies are much higher than the ones used by cellphones in order to carry more data.
As far as how fast that data can be transferred, Wi-Fi technology uses 802.11 networking standards, which come in varying speeds and price points. The first version of the 802.11 protocol was released in 1997 and reached link speeds up to 2 Mbps. The newest standard, 802.11ax, was released in 2019 and is faster than previous iterations, prone to less interference and maxes out at 9.6 Gbps.
What can be done with Wi-Fi?
Wi-Fi isn’t just about accessing the web. The convenience and connectivity of Wi-Fi can also make everyday life much easier. With Wi-Fi you can:
- Sync smart home devices and control from a central hub like your smartphone
- Share files with nearby devices
- Wirelessly stream audio and movies from one device to another
- Wirelessly transfer photos from your camera to your PC
- Sync media libraries without a USB
- Improve home security with smart locks, monitoring systems and cameras
How to get home Wi-Fi
If you’re like most Americans, you’ve got at least eight devices that use your home internet connection. But if you’re looking to create that seamless experience that Wi-Fi allows, you’re going to need to take a few steps to make sure your home is ready.
Choose an internet service provider
Start by shopping the available providers in your area. Determine your monthly budget, what internet connection types are available and most compatible with your internet activities and what speeds are needed to support all the users on your network.
Get a wireless router and modem
Most providers allow you to bring the equipment of your choice. However, some may require you to rent a specific set of equipment directly from them for the best quality. If you’re able, do your research on routers specifically in order to make sure your device can handle the speeds and amount of devices you’re looking to connect.
Consider a Wi-Fi strengthener
Once you’ve established a connection, you need to make sure that your Wi-Fi coverage is nothing short of spectacular, especially if you’re living in a multi-floor household. Look into a Wi-Fi extender, repeater or booster to push your signal to those hard-to-reach corners and devices.
Start your journey to home Wi-Fi sooner than later. Compare major internet service providers, pricing, speed ranges and more.

How to secure your Wi-Fi connection
Once you’ve established your Wi-Fi connection and synced your devices, you’ll want to take some extra steps to be sure your information and your household is secure. A great Wi-Fi password is one thing, but cybercriminals have ways around the most creative security keyword.
Ways to keep your network and devices away from prying eyes
- Go for strong encryption: Wi-Fi Protected Access (WPA) protection, WPA2 or WPA3 are the newest standards. Hackers are familiar with older standards of protection like Wired Equivalent Privacy, or WEP, and may break-in with ease using the right methods.
- Choose a strong WPA key: Your mother’s maiden name won’t exactly cut it. Pick a lengthy security key with a mixture of random numbers and letters to make your password iron-clad.
- Create a guest network: This is a great way to offer your internet connection to guests without accidentally exposing your network to risks. Activate WPA protections on the guest network and provide the password on request. This will allow you to control who accesses the connection and encrypts each user’s data with a “session key,” essentially protecting guests from each other.
- Hide your network name: Changing your SSID to hidden will prompt users to enter the name and the password to connect instead of displaying it as an option for the world to access.
- Use a VPN: A virtual private network, or VPN, sends your data back and forth via an encrypted connection and blocks your location information. With a good VPN, like NordVPN, for example, hackers could access your network and still be blocked from sensitive information.
