Since I ran some update in the past week or so, I have not been able to get a wired connection. Specifically:
- Initially, during boot up, the ethernet link light is on As ubuntu boots up, the link light will go off Ubuntu reports cable is disconnected If I boot into Windows 7, I can use the internet without issue.
My problem is similar to what is described at: Ethernet Lights Not On When Cable Connected And Not Working

As I lack another network card, I can only use windows right now. Advice on how to fix this is appreciated.
Thanks!
