You can add LAN ports to your Google Nest Wifi router or Google Wifi point by connecting them to a switch.
Note: For Google Nest Wifi, you can only connect additional ports to the router, not Nest Wifi add-on points.
What is a switch?
A switch is a networking device that connects devices (like computers, printers and services) to each other. It serves as a controller to let your devices talk to each other and use the same internet connection.
Connect a switch to a Nest Wifi router or Google Wifi point
Plug an Ethernet cable into one of the switch’s WAN or uplink ports. Connect the other end into your Google Nest Wifi router or primary Wifi point’s LAN port . Learn more about how to hardwire Google Nest Wifi, Google Wifi and other devices.
