Hi. In one room of my house, I have a TiVo, Xbox, and computer. I want them all hooked up to my network. My router [Linksys BEFW11S4] in one room, has 1 cable coming into this room. I have a 4 port router [Linksys BEFSR41] that I want to split the 1 wire coming into this room off to the Xbox, TiVo, and computer. How do I do this? Plugging the incoming wire into the WAN port doesn't seem to work. What do it do?
