Yes. If you would like to hardwire additional devices to your eero network, you can connect a 1Gb/s Ethernet switch to one of the spare Ethernet ports on any eero. Once you’ve connected a switch, the eero port will configure itself automatically.
For best performance we recommend connecting the Ethernet switch to the “Gateway” eero, and ensuring you are using a 1Gb/s Ethernet switch with CAT5e/6 cables.
