Wi-Fi gives you internet access wirelessly, without plugging your computer, TV receiver, or game console into an Ethernet wall port. You can get Wi-Fi in the country or the city, as long as your internet provider supports it. If your home has satellite, DSL, cable, or fiber-optic internet, you’ll need to plug your Wi-Fi router into the wall port to create your Wi-Fi network. If you use WISP or cellular broadband for home internet, you won’t need to create a Wi-Fi network because your wireless signal comes straight from the provider.
