Lenovo USB Dock 3.0
I have a Lenovo USB 3.0 Dock (not sure if 3.0 is a version number or just indicates USB 3). It has an Ethernet connector, and to simplify taking the notebook with me, I was using that port instead of the built-in one on the notebook. But it has never worked real well, so I have been plugging my Ethetnet cable into the notebook. I have seen complaints by other Lenovo users about this. The solution? Disable the built-in Ethernet port under Network and Sharing Center->Change Adapter Settings, and enable the USB Ethernet port. Then reboot. It appears that having both enabled even with only one plugged in was causing IP address conflict problems.
