Hi,

 

I have the exact same wireless card and dis that and it was successful! The card is recognized as an Airport Card.

 

1. Grab the Intel 10.4.5 update from the Apple Website: http://www.apple.com/support/downloads/mac...45forintel.html

 

2. Mount it on your desktop (Double-click in it)

 

3. Copy the file IO80211Family.kext from the folder "/System/Library/Extensions" of the update and paste it to the one of your system "Volume Name/System/Library/Extensions/"

 

4. Repair permissions using Disk Utility or terminal or you can do it manually

 

5. Load the extension using terminal using these commands (I think this step is optional because I don't remember if I did it or not)

sudo rm /System/Library/Extensions.kextcache

sudo rm /System/Library/Extensions.mkext

sudo kextload /System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AirPortAtheros5424.kext

sudo kextload /System/Library/Extensions/IO80211Family.kext

sudo kextcache -k /System/Library/Extensions/

 

6. Reboot and you should have the card recognized in the Network Preferences.

 

Good Luck ;)
