How to Make Your Computer Wireless
Wireless network cards allow a connection to the Internet using wireless technology through radio frequencies. Virtually all laptops have a built-in wireless card. To make a desktop computer wireless, you need an expansion card with the external antenna having a PCI (Peripheral Component Interconnect) interface. Wireless cards are especially convenient in a household with several desktop computers connected to one network router to avoid complicated cable routing.
Things You'll Need
- PCI wireless expansion card
- CD with wireless card drivers (packaged with the card)
- Phillips head screwdriver
- 4mm screw

Turn off the computer. Remove the side cover of the computer case. Computers are shipped with a variety of case designs, so refer to your computer manual for instructions.
Insert the video card into the PCI slot of the motherboard. Secure the card with the 4mm screw.
Close the computer case and turn on the computer.
Log in to the administrator account in Windows XP/Vista.
