Wi-Fi and Ethernet are both ways to connect to the internet. We’ve looked at the pros and cons of both networking technologies to help you decide which is the best choice for different devices and activities.

Wi-Fi is common on PCs, Macs, smartphones, and smart devices. The flexibility of Wi-Fi means you’re not tied to an Ethernet cable when you go online, as was the case years ago. But Ethernet connections offer many advantages, including speed and reliability. It’s important to understand when a Wi-Fi connection makes sense, and when it’s best to rely on an Ethernet connection.

Ethernet is the term used for a wired network. It is when you physically connect a computer to a router using an Ethernet cable (sometimes called a CAT5 or CAT6 cable) to access the Internet. Using Ethernet requires little setup from the computer owner; just plug it in. If you are connecting a home network with more than one computer, there is more setup required. Being physically connected to a wired network limits your ability to move your device around.

Wi-Fi is the untethered version of networking. No wires or cables are needed; simply connect to a Wi-Fi network and go online. Businesses like Starbucks and other restaurants offer Wi-Fi as standard, so customers can connect a smartphone or laptop and go online. Wi-Fi is flexible and convenient. Setting up a Wi-Fi connection is easy, but users must search for available Wi-Fi networks and enter a password.
