I have a Pavillion ze5375us notebook. All of a sudden my ethernet connection just quit working. Now, whenever I plug an ethernet cable into the jack, rather than the light just turning green and staying on, it flashes the green light then flashes the orange light then they both turn off. This repeats about every 5 seconds. I'm pretty sure this is a hardware problem because I have tried three different cables in both Windows and Linux and have experienced the same issue. I think the problem could be a bad pin in the jack but I'm not sure. Does anyone know if this is the case or what else could be wrong. Any help in addressing and fixing this problem would be great.
