One hallmark feature of many modern computers, like the Compaq Presario, is a wireless card that allows you to connect to the Internet anywhere there is a signal. This is a great and convenient feature, but like any internal component of your computer, it can damage or break over time. If your wireless card breaks or you simply want to upgrade to a better card, you can replace the wireless card in your Compaq yourself.

  1. 1

    Turn off your Compaq Presario and make sure all connector cables are removed from the device. Close your computer, turn it over and slide the battery out of its compartment on the bottom of the computer.

  2. 2

    Locate the wireless card compartment on the underside of the computer. It is the smallest of the three compartments there. The other two are the hard drive and RAM compartments.

  3. 3

    Use your Phillips screwdriver to remove the single screw located on the side of the wireless card compartment cover. Set the screw aside and lift the cover up to remove it. The rectangular wireless card will now be exposed.

  4. 4

    Use your fingers to disconnect the two wireless antenna cables located on the top of the top corner of the card. The card will now be free in the compartment.

  5. 5

    Remove the old card and slide the new card (available from your Compaq retailer or online) into the compartment, making sure the antenna connectors on the card are closest to the antenna cables in the computer.

  6. 6

    Connect the antenna cables to the card and replace the compartment cover. Replace the screw and your Compaq's battery and you are finished.
