How to set up my wired internet?

I know this is my second question in quick succession, but I'm having troubles with my Netgear router in terms of actually setting it up with my DSL cable. The router is in my room, however I am currently connected wirelessly as I failed drastically attempting to set my internet up with cables. I have a cable running from the back of my PC into my router; a green light is confirming that the cable is working, however I want to be rid of wireless and back onto wired. I'd be very appreciative if someone can give me a quick run down on how to do this; there seems to be a few options for wired internet setup, but I'm too skeptical to believe that any of them will give me the results I want. I have a Netgear installation CD which claims that no router is attatched and/or the router is not working... which it blatantly is. Any suggestions would be much appreciated. Thanks in advance.
