WITH 10.4.x
Checked with 10.4.8/.9, gives you a 100% airport extreme experience.
For use with 10.4.10+ you need to copy the kext from one of the previous versions. You can get it easily by downloading Apple's 10.4.8 update, then using Pacifist to extract the IO80211Family.kext


WITH 10.5.x
Using the 10.4.8 kext with Leopard gives you a working airport extreme, but only for WEP or open networks. WPA is proving a bit belligerent, you can connect to wpa2/wpa networks using the "chipxsd method" described at the end of this post. Editing the 10.5 kext can lock up your system when trying to use your airport. Feedback would be greatly appreciated if you have found a way, or even if you tried and failed.

Leopard "instructions" after the Tiger ones.


10.4 up to 10.4.8


Manufacturer ID: 168c
Device ID: 0013

(168c:0013)


Edit:

/System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AirPortAtheros5424.kext/Contents/Info.plist

from

<key>IONameMatch</key>
<array>
<string>pci106b,0086</string>
<string>pci168c,1c</string>


change to

<key>IONameMatch</key>
<array>
<string>pci106b,0086</string>
<string>pci168c,1c</string>
<string>pci168c,13</string>

if your manufacturer & Device ID are different, just change the line to

<string>pci{man ID,Dev ID}</string>


Then

sudo chown -R root:wheel /System/Library/Extensions/
sudo chmod -R 755 /System/Library/Extensions/
sudo rm /System/Library/Extensions.mkext
sudo rm /System/Library/Extensions.kextcache

(Or, use the script in the attached .dmg file if you can't be bothered cleaning up permissions by hand)

Reboot...

and voil� detected as an airport extreme card


LEOPARD INSTRUCTIONS:

The previous kext method:

For use with 10.5 you need to copy the kext from one of the previous versions. You can get it easily by downloading Apple's 10.4.8 update, then using Pacifist to extract the IO80211Family.kext

Edit the kext as per the Tiger instructions above...

(Thanks Eclau.)




The new kext method

For 10.5, follow the same procedure, but edit the System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AirPortAtheros.kext




warning:

With Leopard kexts a lot of computers get this problem -consider it a "work in progress." This seems to help in some cases:



Connecting to WPA/WPA2 in 10.5

To connect to WPA/WPA2 networks follow this guide (thanks chipsxd). Your airport icon in the task bar may or may not work, and, you might get an error at the end of the steps - BUT you will be connected to the network



A little tip to make life easier. under /system/library/CoreServices is the Network Diagnostics.app. Drag it onto your dock and use it to connect - saves a few clicks

To make it connect automatically at login:

Use chipxsd's script from here

or:



Note: if you get these symptoms:



Then
