I am unable to connect to the internet on my laptop. When I try clicking on the airport icon, I keep getting the message ‘No Airport Installed’.
How do I correct this issue?
Hold down the power button for 10 seconds perhaps after reboot will detect your Airport Card.
First try a Parameter RAM reset:
Restart your Mac and immediately press and hold "cmd + alt + P + R" on your keyboard until you heard the 'gong' for the third time. Let go of the keys and boot up normally.
(a) open up System Preferences, go to Network and at the top click the drop-down menu and create a new location
(b) force a re-detection of the hardware via Terminal.app
open up a Terminal window, type & run the following command:
(c) delete the following preferences file containing network hardware information then restart your system
If all these things fail you could try re-installing OS X, run the Apple Hardware Diagnostics and finally go to an Apple authorized service provider and have them look for the actual cause.
