What is Wi-Fi?
With your modem providing the Internet connection into your home, you can now connect your device to the modem over Wi-Fi.
Connecting to Wi-Fi involves connecting your computer, tablet, or smart phone to your ISP’s network without using a physical wire. This “wireless” connection is made possible by Wi-Fi technology; specifically, by a second device in your home called a router.
The Wi-Fi router uses radio technology to broadcast a unique name (also known as a service set identifier, or SSID), which you or your ISP chooses when the router is first set up. When you’re on your laptop or other device, you can see a list of other Wi-Fi routers nearby such as yours and your neighbors’. You can select your router name from the list and enter the router’s password. And just like that, you’re connected to WiFi.
