I searched everywhere to figure out how to get my Linksys EG1032 v3 Gigabit Network Adapter to work with Mac OS X Leopard, and since I finally figured out how to get it working, I thought I would share it with the rest of you.
The Linksys EG1032 v3 Gigabit Ethernet Adapter has a Realtek RTL 8169S-32 chipset. What this means is that we can use the existing AppleRTL8169Ethernet.kext in /S/L/E/IONetworkingFamily.kext/Contents/PlugIns and simply update the info.plist with the Device ID for your Linksys EG1032 v3 Gigabit Ethernet Adapter, and copy it directly to /S/L/E.
If you want to skip all these steps and just download the kext I modified from 10.6.7, then please DL the attached zip AppleRTL8169Ethernet.kext.zip 42.54KB 166 downloads, or with install script AppleRTL8169Ethernet.kext.with.install.script.zip 43.88KB 100 downloads.
To find out your Device ID (which should be 0x10321737 for this card) you will need to use DPICManager DPCIManager_02.zip 159.22KB 109 downloads.
When you run DPICManager, you should see a line that looks like this:
1737:1032 Linksys Gigabit Network Adapter
1737:1032 means that your Device ID is 0x10321737.
To edit the Info.plist may use your TextEdit.app, or use Property List Editor which is available free when you install Apple's Xcode. After installing Xcode, you will find Property List Editor in /Developer/Applications/Utilities.
Copy the AppleRTL8169Ethernet.kext from /S/L/E/IONetworkingFamily.kext/Contents/PlugIns to somewhere on your Mac. Now, right-click on the copied AppleRTL8169Ethernet.kext and select Show Package Contents.
Under the Contents directory, you will see Info.plist. If you right-click this, you may select Open With.
To edit Info.plist with your Property List Editor:
1. Expand Root, IOKitPersonalities, & RTL8169/RTL8110
2. Add your Device ID (0x10321737) to IOPCIPrimaryMatch, which should now look like:
0x816910ec 0x816710ec 0x103217373. Save
To edit Info.plist with your TextEdit.app:
1. Find the following code:
<key>IOPCIPrimaryMatch</key> <string>0x816910ec 0x816710ec</string>2. Replace with:
<key>IOPCIPrimaryMatch</key> <string>0x816910ec 0x816710ec 0x10321737</string>3. Save
I would recommend installing AppleRTL8169Ethernet.kext directly to /S/L/E. That way it should continue to load after using Apple Update until Apple changes something in the actual /S/L/E/IONetworkingFamily.kext/Contents/PlugIns/AppleRTL8169Ethernet.kext. (Current version for 10.6.7 is 1887.)
The easiest way to do this is to copy AppleRTL8169Ethernet.kext to /S/L/E and then rebuild your kext cache. You can rebuild your kext cache by entering the following commands in Terminal.
sudo chown -R 0:0 /System/Library/Extensions/* sudo chmod -R 755 /System/Library/Extensions/* sudo rm -Rf /System/Library/Caches/* sudo touch /System/Library/Extensions/
sudo chown -R 0:0 /System/Library/Extensions/* sudo chmod -R 755 /System/Library/Extensions/* sudo rm -Rf /System/Library/Extensions/Caches/* sudo rm -f /System/Library/Extensions.* sudo touch /System/Library/Extensions/
After successfully installing AppleRTL8169Ethernet.kext, you may need to go to the "Network" section of your System Preferences and add the interface by using the + sign at the bottom of your listed interfaces. (However, it may recognize that you have a new adapter automatically.). I would also recommend removing any Ethernet interfaces that are invalid (do not have a MAC Address under "Advanced" -> "Ethernet").
If you use the kext I modified instead of creating your own, and your Network Card still isn't recognized, verify whether or not the Device ID of your card matches the one I listed above. If you have a different Device ID, you will need to modify the Info.plist with your cards Device ID.
