I have fairly new HP server: ProLiant ML150G6. On board video only supports low resolutions. Installed NVIDIA GeForce 210 (required a DVI-VGA adapter for my ViewSonic monitor).
Card works great, but since I installed the card, the onboard networking has stopped functioning: Tried with two different cables, verified as working, and booted both to Windows 2003 server and Ubuntu 12.04 - always the same result: "network disconnected" although the green light in the machine and the light on the router indicate that there is a physical connection. Seems the video card has created a problem with the onboard networking.
What's wrong? How do I fix this?
