Hi. I have just set up my home for network. I ran 1 wire from the router to this room, where I have a computer, TiVo, and Xbox, all which I want to connect. I bought a Linksys 5 port switch. I hooked the wire comming in into the computer to test it out, and it works, connects to the internet and other computers connected to the router. Then, I unplugged it from the computer and plugged the incomming wire into Port 1 on the switch, and the computer into Port 3, TiVo into Port 4, and Xbox into Port 5. None of them can connect to the internet, my computer can't see the other computers, or even get an IP. It just defaults to the 169. The lights on the switch all came on, but the incomming from the router activity light is constantly blinking. What is wrong?
