wi fi hardware not installed

Exact same problem happened, after water spilled onto the computer. I've done this before, regrettably, and I ended up replacing the keyboard. This time, it's the network card or something. After the computer dried up, all of the following services were gone: bluetooth, wireless, ethernet. Surprisingly, in the "about this mac" section, the hardware and addresses were still known by the computer, but none of these functions are working.

I will do some research and figure out what needs to be replaced. I am hoping it is just an "airport" or COMM board, and not a complete motherboard, etc.

To be continued...

<POST UPDATE>

I have learned enough to say that if you've lost the network capability (wifi + bluetooth) then water probably reached the logic board. I opened up my 13" Air and I could see corrosion and pock marks on probably more than a dozen components. Inevitably these parts were shorted out at some time. What is surprising is that the laptop even turns on, at all!

So in this case, I think there are two items to check or replace:

- Airport Card

- Logic Board

In my case, it is obvious that the logic board will need to be replaced, due to the notable physical damage. I am unsure if the Airport card has been damaged too. So I will start with the logic board, then replace the Airport card if needed.

Happy hunting! D
