A router is a device that provides Wi-Fi and is typically connected to a modem. It sends information from the internet to personal devices like computers, phones, and tablets. These internet-connected devices in your home make up your Local Area Network (LAN). Once a modem brings in information from the internet, a router distributes this data to your personal devices.
Note: To use Google Wifi, you’ll need to set up one of your Google Wifi points as a router (primary Wifi point). Connect your router or primary Wifi point to a modem with an Ethernet cable. Keep in mind, some apartment buildings and dorms don’t require modems for broadband connections. If this is the case, you can plug your router directly into an available wall Ethernet port.
