Cannot Turn on Airport Card after Archive Install of Leopard

I was careful to use Archive/Install preserving users when upgrading from 10.4.10 to 10.5.

However, now my airport icon shows as an empty pie wedge at the top of my screen. If I click on it, I can see, "Turn Airport On" and "Open Network Preferences". Using Turn Airport On has no effect. I have also tried going to the Network preferences and using the "Turn on Airport" button.

If I look in my log file, I see the following...

"Oct 28 21:09:29 Macintosh SystemUIServer[249]: Error: ACInterfaceCreate() no AirPort interface found for en1
Oct 28 21:09:29 Macintosh SystemUIServer[249]: Error: ACInterfaceCopyStatus() called with invalid interface

Oct 28 21:09:54 Macintosh SystemUIServer[249]: Error: ACInterfaceCopyStatus() called with invalid interface"

I have deleted Airport preferences files, and did not have AppleAirport2.kext in my System/Library/Extensions folder.

I have also cleared out my /Library/Startupitems and /Library/Preference Panes folders.

Not sure where to go next. I do not want to reformat and do a clean install.

Thanks for any suggestions.

Sincerely,

Rusty

This same thing happened to me. I was able to get Airport back using the following procedure.

1. Connect to network via Ethernet.
2. Go to Network in System Preferences.
3. Select AirPort and under the gear dropdown choose Make Service Inactive.
4. Hit the plus and add a new AirPort service (Airport 2 or whatever).
5. In the Advanced tab add the name of the wireless network you wish to join.
6. Hit Apply.
7. After a few moments, the new service found my network. I deleted the "original" Airport service and renamed the new one to Airport.

Hope this works for some other folks.

Wow! Thanks so much for this answer, and thanks to Google for making it so easy to find. I seriously was ready to reinstall OS X 10.5 from scratch just to get my airport working again before leaving on vacation...I can't imagine how many hours this just saved me.

Airport working perfectly now 😀

btw - I just installed the 10.5.2 update thinking it would help, it did not.

The fix worked for me as well, even though the only thing I COULD do was add another "airport" to the list. I had to restart to get everything working properly, but WOW, what a relief, especially after a day of having to reboot everything from scratch on my new macbook.
Thank you so much.

Good solution below.
Zapping the PRAM has worked for me though.
