Not only did I NOT have wifi, but I didn’t even have an option for “wifi” under network preferences. When clicking the (+) under network preferences I only got options for Firewire, Ethernet, Bluetooth DUN, VPN PPPoE, and 6 to 4.
I tried a number of “fixes” including terminal commands to manually turn the airport power off and on again, deleting the existing wifi option (the one that wouldn’t turn On) using the (-) button, and restarting my mac numerous times both in Mac OS and my bootcamp Windows OS.
Finally, i fixed this issue doing the following:
- Restart your Mac.
- upon start-up, hold down the Opt key until you see your drives.
- click on the recovery drive (note: this will not affect or delete any files you currently have).
- login if needed.
- in the top right hand corner you will see the Wi-Fi icon (hopefully). Click the icon and then click “turn wifi Off” and then again click “turn wifi ON“
- restart your Mac again and start it up normally.
