I recently went to India and over there I had to configure my laptop to use Broadband internet. So I followed a guide similar to this one. Everything worked fine and I was able to get online, however, when I came back to states my ethernet connection does not work anymore. When I simply plug-in the ethernet cable, the light blinks but nothing happens on the laptop. My wireless still works.
Is there a way to reset my ethernet settings back as they were when I first installed ubuntu so that everything works as desired?
