Router for new computer
Hey all. I'm going to sound like an idiot, but anyway. I'm buying a new computer (for my bedroom). I've allready got a computer in another part of the house with a DSL modem (plugged into the phone line), because DSL is all that's available in my area. With my new computer upstairs, would I need to buy like a router or something to get internet access to my upstairs computer? How do they work, anyway? If you can't allready tell, I know nothing about routers. Thanks.
