Let them get the modem set up on 1 computer, as is usually included in
installation, then go buy the wireless network components and read the
"quick setup" instructions. In the end, you'll have as many
computers as you want screaming on the internet by simply installing
a wireless card in each, pay 1 monthly service, no holes and mess all
of cables all over the house (and the costs of having someone drill
all those holes), and no extra monthly "home networking" costs.

I hope you'll permit a friendly amendment.

DO NOT hook up a cable modem directly to a computer! The output of the cable
modem should go first to a hardware router/switch. To this, either wired or
wireless, the computers are connected. In other words, the router/switch
(switch=high-speed router), sits between your computer(s) and the internet.
This configuration enables hardware anti-intrusion, blocking, firewall
capability.
