DO NOT REPLACE THE KEXT... It won't even find your AirPort card if you do...

Working on extracting the old one from the restore DVD...

Haha yeah too late. :p I probably have to reinstall Leopard now.

Thanks a ton for the help man. I'm not at home right now so you're a life saver. :)

Yeah... I'm not having great luck so far. Some posts on the Apple boards aren't looking to hopeful either...

And I just had to go and try it... lol...

[edits below]

I'm back to a working state... but I tried so many things I wonder which it was that has "fixed" it.
I too completely lost my airport card... [more edits below]

On my new MacBook Pro this is what I did... (now this is using the included install DVD which is 10.5.5, you might have to use the 10.5.5 combo updater or something similar... maybe at the least this will give someone a direction to head in)

sudo rm /Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
sudo rm /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
sudo rm /Library/Preferences/SystemConfiguration/com.apple.network.identification.plist

cd /System/Library/Extensions
sudo rm -rf AppleAirPort.kext
sudo rm -rf IO80211Family.kext
sudo rm -rf IONetworkingFamily.kext

I don't know if the below is the right path as I copy the whole DVD to a partition on my laptop HD for these very reasons ;) So check to make sure it's right...

sudo cp -R /Volumes/Mac\ OS\ X\ Install\ DVD/System/Library/Extensions/AppleAirPort.kext ./
sudo cp -R /Volumes/Mac\ OS\ X\ Install\ DVD/System/Library/Extensions/IO80211Family.kext ./
sudo cp -R /Volumes/Mac\ OS\ X\ Install\ DVD/System/Library/Extensions/IONetworkingFamily.kext ./

cd /System/Library
sudo rm Extensions.mkext

and reboot...

I had also removed the airport from the network preferences, and then re-added it. Some of this I did from the Mac OS X Install DVD, so you might have to try that as well. I really wish I had better instructions and a better idea of what fixed it, but, this is the best I can do...

Well, it's working for me anyhow... best of luck!
 
Earlier I reported that my Blackbook was fine, but it seems my wireless n may have been disabled by this update as I can't seem to connect to my time capsule, which broadcasts an n only network. Not confirmed this yet but I see no other reason why my lappy would default to my a/b/g network rather than the TC, when the TC is much closer.

Well now I'm connected to my n-only TC, so looks like everything is fine really. Not that I'm complaining.
 
I see some of you messed up installing the kernel extension.
What you need to do is..

- Move the /System/Library/Extensions/IO80211Family.kext that came with the pulled Apple Update to your Trash.
- Download the one linked earlier.
- Copy that to /System/Library/Extensions.
- Open Terminal and execute these:
sudo chown -R root:wheel /System/Library/Extensions/IO80211Family.kext
sudo chmod -R 755 /System/Library/Extensions/IO80211Family.kext
sudo touch /System/Library/Extensions
- Restart and all set.

The posted kext is the latest one from the 5.5 combo update. Whatever kexts you are going to get from the restore DVD (unless its 10.5.5 restore DVD) will be older, out of date versions and may cause incompatibilities.
 
I don't know if this is a coincidence, but literally overnight my battery is crapping out. I was at 98-99% health earlier this week and this morning I noticed that my battery was at "0%" despite running fine

Fired up Coconut and now my battery health has dropped to 44% (my macbook is 3 months old, 32 cycles)

Damn man, I owe you at least a few beers. Thank you tons. :D I was so getting mentally ready to reinstall Leopard (and reinstall apps, settings, etc.). I can't try this yet but I'm confident it'll work. I'll check back in later to confirm.

I'm probably being superstitious too but I also noticed iStat claiming my batteries health was suddenly at 90% (when it was usually at 98%) , then a few days later is now at 93%. This is probably nothing though.
 
this airport update is no where to be found. Some say Apple pulled it
for unknown reasons.

Yeah... and in some folks cases it seems very good reason. It's hard to say if all the issues are update related, but for now it's not a bad thing for it to be missing.

This method worked for me last night. So try it out!
 
I contacted AppleCare to see what's up. The rep told me that their KB article/memo/etc mentioned only the error with being unable to turn AirPort back on. He had not heard of the loss of "n" connectivity, and it wasn't anywhere in their documentation. So either they're unaware of that facet of the problem or it's not documented yet.

Well done! Pat yourself on the back. You'd have found that out just by reading the thread before posting. Even just the first page would have done.

:D
 
how can i check if i downloaded it? i'm pretty sure I didn't install it since I haven't restarted my computer to allow updates to install. But I'm not sure if I downloaded it. Is there a way to check it someplace?

System Prefs > Software Update > Installed Updates.
 
no but see that tells me what i have installed. I'm looking to see what I have just downloaded, but not installed yet.

Ahh ok, I follow you now. There probably is a way, but im not sure what it is (I expect downloads go into some type of not very accessible cache folder?)
Personally, I don't allow automatic downloads anyway.
I expect the update will be reposted shortly, in modified form. So you could wait and download/install that. That way, if you did download the previous one, it will be ignored/trashed. Won't be long surely..

Ok that's a good idea. Thanks for the suggestion. No harm in waiting :)
 
Went to update airport after seeing the update earlier in the week and it didn't show up..and now I know why..duh. Good to know that I didn't pull the trigger earlier. Glad I checked here.

FYI... People with Macbooks should not do this. It doesn't work. I know it doesn't work because I was able to replace my original file (2.1.3) and the terminal commands worked. I was forced to do this because the file posted (2.1.2) blocked airport when I restarted. So it's possible there is a different file for MBs and MBPs.

(Or I am screwing something up.)

Any tips?

:D

There is still no airport update to be found. Unlike many, I don't believe
everything I read. I actually check things out.
 
I just got my Mac back today from repair and told me I have this update (plus the CD/DVD sharing update) to install.

I installed it, then rebooted and I could no longer connect by wireless or ethernet (got a self-assigned IP).

Did a wee search, and it works if I disable the OS X firewall. However, once I enable it again, it doesn't work.

Argh.
