Understanding WiFi and wired connections

WiFi provides a wireless internet connection, while Ethernet provides a corded connection. Many routers allow you to connect both ways: wirelessly or using a wired connection. Understanding the differences between Ethernet and WiFi can help you decide how you would like to connect.

Should you connect over WiFi or Ethernet?

Here's a look at the pros and cons of WiFi vs. wired connections

How to get a wired connection

Many routers support a hardwired Ethernet connection, but you’ll want to check your specific router to make sure.


Here's what you need:

  • An Ethernet port on the device you want to plug in
  • A USB adapter if you don't have a port on the device 
  • An Ethernet cable designed for the specific speed range
