I second the suggestion for a mesh router. I have a Juniper, same layout as a Lantana. I have a three node eero mesh router with the main in the living room, another in the laundry room and a third in the front bedroom. Each has two Ethernet ports. I have a slammed WiFi signal everywhere in the house as well as all around the house outside. No wiring needed.
