Wi-Fi vs. wired speeds
Your Google Fiber network device serves as a router for both your wired and Wi-Fi connections.
Wired connections have higher bandwidth than Wi-Fi connections. When connected by Ethernet cable, a lot of data can move quickly and directly between your computer and router. On the other hand, Wi-Fi radio signals travel through the air and often run into interference from objects or other signals. This means that less information can be transmitted between a Wi-Fi device and router, resulting in slower Internet speeds.
