Many newer laptop computers have a wireless network adapter already built into the laptop’s PCI slot. However, not all computers are equipped with an adapter. This slot is typically located on either the back edge or side of the laptop and a PCI network card can be inserted into it. These cards can allow your computer to access wireless networks in your home, hotels equipped with wireless Internet and cafes with wireless Internet.
Properly power off the laptop before opening up the computer with the “Shut Down” option.
Unplug the computer from the electrical outlet. Remove any external devices such as a printer or headphones. Note the locations of any devices so you know where to plug them back into. If you need to, make notes.
Flip the computer over to remove the bottom case. Use the appropriate type screwdriver to remove the screws securing the case. Since the PCI slot is usually located near the back edge or side of the laptop, you may not need to remove the entire case. Refer to your owner’s manual to find the PCI slot for your particular computer brand since this may vary. Save the screws in a safe location for later. Touch the power supply — a large rectangular metal block in the laptop– to ground yourself before proceeding.
Locate an empty PCI slot to insert your card. These are long rectangular shaped openings. A modem or Ethernet card may be taking up current slots. If you are not using them anymore and need to make room for the PCI card, then remove them.
Unscrew the metal section that fills the back of the computer because of the absence of a card. Use the appropriate type screwdriver to do this. Save the metal piece and screws in a safe location in case you need it later. Push the wireless PCI card into the available slot in the laptop.
Position the card so the antenna is facing upwards. Make sure you do not touch the circuits on the card and do not push too hard on the card when you are inserting it.
Replace the bottom cover on the laptop by tightening the screws with a screwdriver. Position the computer upright and plug it back into the power supply. Reattach any external devices you will be using. Turn on the computer and restart as usual.
Wear an anti-static wristband or a ground strap when you are working on a computer’s internal parts. Static electricity can damage the computer’s components.
