phsilver,

Install or recent changes
Could you describe your method of install? Did you install any specific kexts(drivers) to handle your network adapter? Did the network adaptor worked properly under OSX but has not stopped working?

Current installed kext
If you can run the following command in Terminal, it will give us a bit more information. Reply back with what you find:
Code:
kextstat | grep Ethernet
Dump Preferences
I would start by dumping the current preferences for your networking. To do so, remove all instances of ethernet adaptors using the minus button in network preferences.

Open terminal and type:
Code:
cd /Library/Preferences/SystemConfiguration
sudo rm -R com.apple.airport.preferences.plist
sudo rm -R com.apple.network.identification.plist
cd /User/INSERTYOURUSERNAME/Library/Preferences
rm -R com.apple.internetconfigpriv.plist
rm -R com.apple.internetconfig.plist
Repair permissions
While you are in Terminal, you may want to repair permissions. You could get lucky and your problem may be permissions based.

The following command will repair permissions throughout your system. This is relative to how you installed. You may need to take additional steps.
Code:
diskutil repair permissions /
sudo chown -R root:wheel /System/Library/Extensions
sudo chmod -R 755 /System/Library/Extensions
Restart using the flags -f -v

If the aforementioned did nothing to help, you may consider looking into alternate kexts. I would strongly encourage you to backup your system prior to modifying system files.

In addition, I always prefer illuminate as many variables as possible prior to diving into the system files. If you have a USB ethernet adaptor, you should give it a try.

Do some research via google such as:
