You can manage your network settings from the Network tab in your Fiber account.
To open the Network tab:
Sign in to Fiber using the email and password you use for your Fiber account.
Select Network at the top-left corner. (If you don’t see it, click the navigation menu to display the selection.)
The navigation pane on the left displays all devices on your Fiber network. The Network Box always appears at the top of the list. Below the Network Box are the TV Boxes and any hard-wired devices. Any devices that are hard-wired to a TV box appear below that TV Box. Devices connected wirelessly appear in the Wifi Devices section in the order in which they were connected to the network (even if they are not currently connected). (It can take a few moments for the screen to refresh and show newly connected devices.)
You can change the names of your network and TV Boxes, as well as your non-Fiber devices. Renaming devices allows you to easily determine which devices are or have been connected to your network. If you don't provide a name, Fiber uses the name supplied by the device, if any, when it connects to your network, for example, Android-wrbou10323dw0.
TV Box names are used in Fiber and in screen selection menus displayed by the Google Fiber mobile app, so it's a good idea to name them related to their location, for example, Bedroom 2 TV.
The dots next to each device indicate whether the device is currently connected to the network. Green indicates that the device is connected; gray indicates that it is not connected. If a wireless device is dimmed, it indicates that the device isn't currently connected.
When you select a device in the navigation pane, the settings pane displays the current settings for that device.
