I'm experiencing this problem later this afternoon. I cant connect to the internet because it shows that the cable is unplugged. I tried everything I know about troubleshooting but still problem remain unsolved. I also had a more than 30 mins technical assistance from my internet provider via phone and we both conclude that maybe its the device that has a problem. That's after I tried to plugged the internet cable to my old laptop and I had connection. This problem is with my 5months old laptop with Windows 8 operating system. I don't have router, only direct cable/canopy to my laptop. Hope somebody would take some time to post about the solution for this kind of problem.
