Sometimes when booting or rebooting my pc, the nic shuts off. If I boot into Windows, it turns it back on about half way through the boot process. If I boot into Ubuntu, it doesn't turn back on. If that's the case, I have to shut down and unplug the box for a bit, then it works fine. I can go from using the web in Windows and then restart and have a non-functioning nic unless I go back to windows. If the system boots normally, the nic activates when the pc is turned on. Any ideas?
