Running two PCs off a cable modem...
My sister wants to run her comp off my mother's cable line, we have two

One's mine, the other is for her office. In any event...whats the better way to go, Router or Hub?
Is my understanding correct that with a Hub one computer needs to work as the "host" with a little mini-network setup and that a router just allows both computers to use the same device? Errr what? Not a networking guru...
Whats the difference in price with regular and wireless routers? Do you need a wireless nic then? Ejuhmuhkate me!
Linksys good brand, yes?
