You can add LAN ports to your Nest Wifi Pro router, Nest Wifi router, or Google Wifi point by connecting them to a switch.
If you use a switch, we recommend using an unmanaged switch or configuring a managed switch to disable Spanning Tree Protocol (STP) and forward Bridge Protocol Data Units (BPDUs) when STP is disabled. This will avoid technical issues with some managed switches as it relates to routing and network loops.
Note: The Nest Wifi point doesn't have Ethernet ports and can't be hardwired.
What's 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 Pro router, 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
