Alright, here is what I want to do. I have a cable modem up in my room w/ @home cable service. My sister wants cable internet on her computer downstairs. Her room is about 50 feet away from mine. How would I do this? I don't want to pay anymore money per month, or buy another modem, I just want us both to be using 1 modem (and we will both beable to surf at the same time also). I know there is a way to do it but I don't know the name of it, or how to do it. I know this isn't much of a description, but it was like a year ago, and im not much of a cable/dsl guru. Anyone know how I could do this? Is there instructions online somewhere? I couldn't look it up on google cause I dont know what it's called. Thanks.
