At some point throughout the course of owning a laptop, there may come a time where you will have to remove and replace your wireless LAN card on your own. Replacing a wireless LAN card is a smart upgrade in that it will provide you with faster and more responsive Internet access regardless of where you are picking up the signal. While it may sound like a difficult task, it is actually quite simple if you follow the proper instructions.
Find and remove the wireless LAN card compartment cover and unscrew it using a precision screwdriver. Precision screwdriver sets can be found at any local hardware or computer electronics stores. The compartment cover is usually located in the top or bottom left-hand corner of the base of your computer (the location will vary depending on the manufacturer). http://www.papatek.com/PCI-Wireless-LAN-Card
To remove the card, gently press outwards on the holding clips on the outside of the card to release the card. Once you hear a clicking sound and the card pops out of place, gently remove it and place it to the side of the computer.
Remove the antenna wires from the edges of the wireless LAN card. To do so, grip the gold plug on the card where the wires attach and pull them straight up using a slight twisting motion. Do not pull the wires themselves as this will damage the hardware. http://www.papatek.com/USB-Wireless-LAN-Adapter
Attach the wires to the new wireless LAN card. You will notice that each wire is a different color–one black and one grey. The black wire attaches to the gold connector that is furthest away from the corner of the card while the grey one attaches to the one closest to the corner.
Press the new wireless card down into the wireless LAN card compartment until it snaps into place. Take a moment to ensure that the wireless antennas are pointing away from the card itself and towards the outer laptop casing.
Reinstall the cover to the wireless LAN card compartment onto the back of your computer using the screwdriver. http://www.papatek.com/Ethernet-PCMCIA/85Mbps-PowerLine-Communication-Adapters.html
