Building Your Network
Simplest way to install a network at your home or office involves talking to friends who live nearby, finding out which Internet service provider has the best deal, and then having the phone company or cable company (or satellite company or whoever) install your whole network, from the get-go. If you can't find the right person at the phone company, hire that ten-year-old next door to help.
Most ISPs will install an Internet connection and hook up a hub with four or more networking slots, for a pittance. The same ISP will no doubt install a wireless access point for a tiny bit more.
