Because some notebooks don't have wireless connectivity built into them, especially older notebooks. They may be fully capable of connecting to a wired network by an ethernet cable, but cannot transmit or receive through the air.

Many notebooks older than 3 years have no built-in wifi capability. An adapter is the easiest/quickest way to go online w/out wires.

If it's not built into the laptop, you need a laptop card to get WiFi working on it. Otherwise, to get connectivity on a laptop you had to be plugged in, which defeats the purpose of having a portable laptop.
Manufacturers finally started putting them in standard about 2 years ago. Before that you had to buy the adaptor
