I have coaxial cables running through my house that branch off of one coming from my service provider. There is one existing LAN on one side of the house with a router and a few devices. I want to create a seperate LAN in a different area of the house Off of one of those cables. I dont want a wireless connection only wired is necessary. I want to hook up a modem and run a wired connection in another part of the house for my pc but i realize that it will be isolated from the rest of my network. Is there some program I can run on my pc that will allow me to connect to my other network without buying a router?
