Hello. I am thinking of switching from conventional routers to the Eero setup. However, I have a specific need that I want to make sure is addressed before I make the switch. I am able to connect my cable modem to one base unit via Ethernet. However, I have an aquarium that uses a controller requiring an Ethernet connection to it. I currently have a Netgear wireless router than I am using for this connection. The spot the aquarium is in does not have access to a wired Ethernet connection.

My question is: if I add a base unit to that room, plugged into the wall, and connect the aquarium controller to it via Ethernet cable, will it provide an internet signal to the controller? I wasn't sure if the base unit in this case would strictly perform as a WiFi unit only or if it could provide a signal to the controller through the Ethernet cable. The controller does not have WiFi functionality and must be connected to a router using a cable.

Thank you!
