For those who are interested, here's a picture of my network setup:
The little black one is the modem/router Verizon gave me. I don't even know why they even bothered to build a router into it, as it only has a single(!) ethernet port.
That's the reason it was connected to a hub.
The blue cable going vertical out of the Lynksys is connected to my brother's computer on the other side of the apartment via a 50 ft. cable. He has a wireless card, but he left it at our parent's place (they have a wireless network, and we didn't until now). Good thing I had that 50 ft. cable lying around...
Not quite as neat as Gewehr's, but it'll do.
