I did what you said and I ran the regular test and the extended test, on both tests the results came back as "no trouble found". Do you have any other tricks up your sleeve? Thanks for helping me!
All kinds of weird fixes for this issue have been reported, most of which make no sense. I think it's usually or always caused by a hardware fault, which may be intermittent -- perhaps a loose connector or a failed solder joint. The AHT doesn't detect it, just as it doesn't detect most hardware faults.
Ok- I'll take it in to the Apple store when I get back to the states. Thanks!
You don't say what version of OS X you are using. If Lion or above, re-boot while holding down Command + R. This is the Recovery Partition...bypasses the main operating...do you have WiFi now? If you do, you don't have a hardware issue. If you don't, most likely you have a hardware issue.
Also, does Bluetooth work? In many systems, Bluetooth & WiFi are on tyhe same card.
Why is my laptop saying I have no wi-fi hardware installed?
