I Have an HP dv7 laptop with Ubuntu 10.10 installed when i plug the cable no connection is established and a white light starts to flashes intermittent, the system tells me that no connection is active I tried to reinstall the OS but nothing works. Any idea?
After all I found the problem was about the "weak-on" setting of the eth configuration. To find it I installed the ethtool to discover all the ethernet configuration settings, as this post suggests Resolution Post
..and incredibly what was the solution?... ..first shut down the laptop ..second REMOVE the battery... oh my... ..third ... everything works!! incredible...
hope this helps
