Wi-Fi speeds on Google Fiber
You can get the fastest possible speeds by connecting your computer to your Network Box or router with an Ethernet cable. When you connect using Wi-Fi, you won't reach maximum speeds, but you can expect faster speeds than you would with other types of wireless access.
You can test your Wi-Fi speed by going to speed.googlefiber.net and clicking the play button.
