I have a strange issue with the Airport Extreme Card in my iBook:

Some weeks ago I managed getting AE in Linux to work using the bcm43xx driver. Since about the same time, Mac OS X does not see the AE Card anymore. It just says there is no Airport Card installed. To exclude anything broken in my OS X installation I also tried this directly with the system profiler booted from the installation CD, but I get the same result. But in Linux AE is still working.

So maybe Linux has changed the card in a way that it is not recognized anymore by OS X?

Is there a way to "reset" the AE Card? Maybe from inside OS X? Should I try to reset the PMU?

cu, Magnum

The driver does nothing permanent to the card. There is an SPROM editing tool that can change values and if you've used this I wouldn't be surprised if there was something changed. You could try resetting the PMU, but I don't know if there will be a difference. Have you checked your system logs in OSX and verified that the Airport2 kext is loading?

I have done nothing special with EPROMS and such things, I just emerged the bcm34xx and the softmac package.

Ok, now I looked into the OS X logs and found the following in /var/log/system.log:

Feb 26 05:16:02 localhost kdernel[0]: Couldn't alloc class "AirPortPCI_MM"

I reinstalled the Airport driver, but not difference.

Also I have run the Apple Hardware Test without errors. Here the AE card is detected.

Do you have an external hard drive that you could use as a test?

What I am thinking is use something 2GB in size or more, do an installation onto the external device using a limited package set (so, just the core os and necissary tools, not the bundled applications, additional font packs, language packs or printer packs).

Then, try it in there.

If it works, then congratulations, you have solved the puzzle.

If it does not work, then I hope you still have some coverage on your system, or if not, maybe swing into a local apple store and pick up an applecare protection plan.

No, I don't have an external drive and also no disc space with HFS partitions for backup, so I just dared to reinstall OS X. Nearly all configurations and files are still where they were before, that's nice with OS X. And Airport works again.

Sorry for the confusion, thank you all :-)
