[amx]

currently my ethernet is set to en3 as interface name but i want to change it to en0. How would i got about deleting and reinstalling the ethernet driver. or is there a way to change that without removing and installing.

There is a way. OSX remembers every ethernet connection it ever sees according to the hardware MAC ethernet address. For instance, if you have an ethernet adapter with the wrong driver OSX will remember it forever as "en0" even if it was never a working connection.

 

There are 2 files you need to edit. I can't tell you what they are exactly since right now I'm booted into XP because my ethernet on Leopard isn't working at all. They're either under /Library/Preferences or /System/Library/Preferences. One is "preferences.plist" and the other is also a plist file that should be recognizable by its name. It is network related and should be obvious. There are sections in it that refer to "en0", "en1", "en2", etc. You need to remove those sections completely. The next time you boot it should see your ethernet as a new adapter and make it "en0". I went through this a couple of times. It's not that hard, and even though I can't be more specific I just wanted to let you know it is possible.

This came in handy. It is a Plist in the /Library/Preferences/SystemConfiguration called NetworkInterfaces.plist

 

I backed up the original, then deleted everything in between the <array> </array> tags (almost the whole file) then rebooted. Interfaces are all re-generated and en0 is detected again. Thanks.
