How to: Airport won’t activate? Try this simple fix
What should you do when your Mac’s Airport wont activate? It’s a fairly straightforward fix and you should be back up and running in a matter of minutes.
When I bought a MacBook, though I really wanted an iMac, I did so because mobility is an absolute must. So, whether I’m sitting in a parking lot somewhere — waiting for practice, scouts, shopping or whatever to end or just having brecky on the deck — my MacBook’s built in Airport Extreme wi-fi just has to work and yesterday it just didn’t.
That is, I often disable Airport via the menu bar to conserve battery and this time when I went to turn it back on, it just wouldn’t — clicking “Turn Airport on” either via the menu bar or Network panel inside System Preferences earned me no love. Moreover, neither restarting nor restarting and clearing the PRAM (press ⌘ + Option + P + R and, yes, I “know” this is useless) did any good.
A quick Google of the phrase “airport won’t turn on” led me to a Apple Support Article that advised this simple (potential) solution:
1. Open the Network System Preference panel
2. Delete Airport by clicking the “-” (minus) button
3. Restart your Mac
4. Open the Network System Preference panel
5. Add Airport by clicking the “+” (plus) button
6. Click “Apply”

And, at least in my case, that did the trick and my Early 2008 2.1GHz MacBook’s Airport is once again fully functional.
