Airport card not detected with Leopard

Same thing happened to me. Updated from 10.3.9 to 10.5, then installed update (over wireless network) of Login & Keychain Update 1.0 and after the reboot, the computer does not recognize the Airport Card.
Console documentation referring to Airport lists the following:

What is that? Failed to check-in?
Any suggestions about this?

Same problem G4 Powerbook

Same thing here. I upgraded my Powerbook G$ and after reboot the computer does not recognize the airport card....

This is a big problem.. anybody called Apple Support? What did they have to say?

Even if you have installed the latest Keychain update, you may be facing this issue.

Some users have determined that an artifact left over from Mac OS X 10.4.x interferes with wireless connections after Mac OS X 10.5 is installed. As explained in this thread, the issue can be dealt with by finding and removing the AppleAirPort2.kext file from your Extensions folder, located here:

Macintosh HD:System:Library:Extensions

It's a simple fix, but one that you would never find on your own. And, it's pathetic that the installation or migrations scripts fail to remove this troublesome component. "

iMac Intel late 2006 Mac OS X (10.5)

I went to the apple/support/downloads page of Apple website and downloaded the Login & Keychain Update 1.0 (dmg file) -and ran that again. The first time was the update that was delivered by Software Update. Then on restarting, the computer recognized the Airport this time.

I also followed the advice in the last post and got rid of that file in the system library.

So we are back to wirelessness. Thank you.

Same issue here - upgraded from 10.3.9 - still not recognising the airport card

This is happening to me too. Dual 1Ghz G4, after an Erase and Install, followed by importing my data from the old drive and install of the Keychain update. I can boot back into Tiger and the card is recognized again. In Leopard, Airport is shown as off, and clicking the button to enable it does nothing.

I did not find the two files to remove mentioned in my Extensions folder, presumably because I didn't do an Upgrade.

I just tried manually downloading the Keychain and Login update and installing from the DMG. No change. Hope we can get this fixed, or Leopard is useless to me. 😟

ZippySeven, Welcome to the discussion area!

Try booting while holding down the SHIFT key. After successfully booting in safe mode, reboot normally.

Thanks for the welcome, Duane.

I booted into safe mode in Leopard. The airport menu said "Airport card not installed" when I checked it. (Probably expectedly so). I then rebooted normally and tried again. This time, as before it said Airport was off, but again appeared to ignore any attempts to start it.
Fortunately I've got the original Tiger drive to use in the meantime. The machine is a long way from my other networking gear, so connecting to ethernet isn't practical.

I suppose I can start over from scratch with another Erase and Install, but I'm still hoping there's a simpler way... Unless other suggestions are forthcoming, the next step might be to install Leopard again, and NOT install the Keychain and Login update to see if that makes a difference. I kind of feel like I'm beginning to grasp at straws though... :/

It's starting to remind me of the days of SCSI voodoo... Change IDs, swap terminators, dance around the computer three times on one foot...

A little followup... I'm doing an "upgrade" now. If that doesn't work, I'll do an Archive and Install, followed by a new Erase and Install if necessary. What's interesting to note is that when booting Leopard from the Install DVD, it recognizes the card just fine and I can get on the network. Also, there were some problems with my keychain file not being found. I manually dragged the keychain file from the other system and used Keychain First Aid, which says it repaired the problem.

To be continued...

Followup... A second Erase and Install did the trick. Airport is now working as it should and I'm now another happy (if a bit frazzled) Leopard user.

I'm now having problems with my Keychain being missing after importing my files from the old drive. Not sure if I'll have to make a fresh account and then manually move files or not. I know that's off-topic for this area, but if anyone has a suggestion I'd like to hear it...

Hi: I recently upgraded from tiger to leapord and whilst re-installing my HP printer, I was asked to restart the aiport express and this destroyed my connection....I have never been able to restart airport since then.

My AT&T DSL is working fine with my Dell computer but when I hook it up to airport, the constant yellow flashing light ....is on.

I dont know what the problem is.??
