How to Make Your Computer Wireless

By Contributing Writer

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

Step 1

Buy a PCI wireless expansion card. There are many available desktop wireless cards. One of them is listed in Resources.

Step 2

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.

Step 3

Insert the video card into the PCI slot of the motherboard. Secure the card with the 4mm screw.

Step 4

Close the computer case and turn on the computer.

Step 5

Log in to the administrator account in Windows XP/Vista.

Step 6

Insert the CD with wireless card drivers into the computer's CD/DVD drive. Follow the prompts to install the drivers on your system. Restart the computer if prompted.

Step 7

Click "Start" in the lower-left corner of the screen and then "Connect to." A list of available wireless network connections will appear. Select a desired connection and click on "Connect."
