How to Set Up a Wired Ethernet Connection for Faster, More Reliable Internet

WiFi is convenient, but a wired ethernet connection is almost always faster and more reliable. If you have ever had a video call freeze, a movie buffer, or a slow download, switching to a wired connection can make an immediate difference. All you need is an ethernet cable and a device with an ethernet port — or a small adapter if your device does not have one.

Ethernet cables look similar to phone cables but slightly wider. They have plastic clips on each end that snap firmly into the port. The most common type sold today is called "Cat 5e" or "Cat 6" — either works well for home internet. You can find them at any electronics or home improvement store. And they range in price from a few dollars to about $15 depending on the length.

To set up a wired connection, you run the cable from one of the open ports on the back of your router to the ethernet port on your computer or other device. The router usually has four to six yellow or numbered ports labeled "LAN" — these are the ones you use for wired devices. Do not use the port labeled "WAN" or "Internet" — that one connects to your modem.

Once you plug in both ends of the cable, your computer or TV will usually recognize the connection automatically within a few seconds. On Windows, you will see a small network icon in the bottom-right corner change. On a Mac, a small dot will appear next to "Ethernet" in your Network settings.

Wired connections are especially helpful for desktop computers, smart TVs, gaming consoles, and any device that stays in one place. They are also more secure than WiFi because they cannot be intercepted wirelessly.
