EoP is worth a try. I am using
THIS. I am a retired 25 year IT Systems Engineer, and this was recommended to me by a client with a setup pretty much as you describe yours. If it doesn't work, just send it back to Amazon.
A key setup point: The node can share a socket but not a plug. Also, the cable from your network should be directly from your router, not an added switch. Read the directions that come with it, but basically, if the nodes see each other, you will have a circuit. Feel free to PM with questions.
