How to Install an AirPort Firmware Card

The Airport Card on your OSX computer is used to access wireless Internet networks in your area. When your Airport card burns out, you can replace it without taking your computer into an Apple dealer. This will not only save you money, but you will be able to get online without having to connect with a wired router. You can perform this task with minimal knowledge on the subject and just a couple of tools found around the house.
