Sharing Internet Connections Wirelessly

It's pretty trivial to use a wireless base station to share a single ISP's Internet connection with multiple computers, and the firewall facilities built into some wireless base stations can improve your ISP security, too. Base stations like the Linksys or AirPort will function like routers; you connect their uplink ports either directly to your Internet connection or through a hub or switch. Individual computers can either be assigned IP numbers on-the-fly by the base station, or be given pre-set ones. The former case is easier to set up, and the latter case results in faster Internet access. Computers set up in a wireless network like this can also directly share information with each other.
