We have had good luck with a couple of “No New Wires” methods of connection such as PowerLine adapters and Wireless Bridges. PowerLine adapters utilize the copper wiring in your electrical outlets as the Ethernet cable. We have used adapters from TP-Link and Netgear with good luck. Of course every house different and we cannot guarantee that these will work in your home. We have also used Wireless Bridge devices which convert an existing Wi-Fi connection into a wired connection.
