I have a motorola surfboard 5100 cable modem and I am not able to use the internet in version 3.8.1. In 3.6, using either kernel, the internet worked without me having to do anything. What can I do to fix this. Keep in mind that I am a newbie. I have tried looking in other topics, but usually couldn't understand what to do or I tried to do something suggested and couldn't. Is there anyone out there that can help me? By the way, it's hooked up via usb, because I have no ethernet.
