What can I do when my MacBook Pro´s AirPort say: Wi-Fi: no hardware installed

Hello there JLpoo,

I have a couple of resources that may be able to help in this situation.

First I recommend resetting your computers System Management Controler, or SMC using this article: http://support.apple.com/kb/ht3964.

This section specifically-

Resetting the SMC on portables with a battery you should not remove on your own

Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).

1. Shut down the computer.
2. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
3. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
4. Release all the keys and the power button at the same time.
5. Press the power button to turn on the computer.
   Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Also the computer has a built in Hardware test you can use. The article for that is named OS X Mountain Lion: Use Apple Hardware Test found here: http://support.apple.com/kb/PH11342, to help determine if you have a hardware issue.

Cheers,

Sterling
