We have some older Intel based white MacBooks that are 5+ years but work well as units in Mobile labs. These machines run a 10.6.8 image and are still capable of meeting teacher/student needs. A few of these units have started experiencing a problem which first manifests in a weak Wi-Fi signal. Machines will sometimes still connect when within 10-15 feet of the airport, only to disconnect. The problem gest worse with time until the Wi-Fi card simply fails to connect at all.
The older G4 iBooks had an easy to access panel underneath the keyboard to replace the card. The white macbooks have a similar card but to access requires one to remove the entire bottom case and keyboard. Not too difficult but just a lot of screws. You need a mini philips (jewelers size 0?) and then just start unscrewing. This model uses a wide variety of lengths so it is a good idea to keep them in piles or equal size as machine is taken apart.

Nice to see heavily laptop machines able to keep working well 5+ years, new battery, hard drive, and occasional Wi-Fi Card seems to be all necessary maintenance to extend these machine to hopefully 7 years. For a laptop in a lab environment I consider this a great lifespan.
Some very early White Macbook Intel models have slightly different airport card layout with 3 antenna cables, may want to check you serial or take a quick peek inside before ordering a replacement part.
