I've got the same problem and i have no real idea on how to fix it, but someone did mention that if you ran netcardconfig as root from a shell, it should help you get on to the internet...it does not seem to save this setting and the next time you boot you may have to run the command again. At least with me it doe not save the setting. It might save it for you.

Is there anyone out there who know how to fix this so I don't have to keep doing this at boot up?
