Feb 21, 2015 7:59 AM in response to Apple Crystalby Eric Root,Go to the menu while holding down the option/alt key and select the top choice (probably System Information). There is a Wi-Fi section in the report. Does it show as installed? If not, either you can check the cable to the Wi-Fi card or take the computer in for testing.
If you live near an Apple Store, make a Genius Bar appointment to have the computer tested. Supposedly there is no charge for testing. Use 2nd link if not near an Apple Store or aren’t in the US. Hardware Repair - Keeping Confidential Data Safe
