I don't have experience with DSL, so the ladies above will have to confirm whether or not it works the same as cable internet service . . . but, this is how ours is hooked up:

Internet cable connects to Modem > Modem plugs into Router > Router broadcasts signal to your computer/laptop anywhere in your house (and a little beyond, which is why you want to password protect your "network", so a neighbor can't use your network)
