I'm waiting for my Dell SmartStep 200N notebook to arrive and I'm thinking about doing wireless networking at home (I have three desktops, cable modem, and hub currently). What is the minimum that I need to have for an 802.11b network? Do I need an access point or simply a PCI card for one of my desktops and a PCMCIA card for my notebook? If I only need cards, is there some advantage to be gained by going with an access point? Any advice would be greatly appreciated.
