|If you're not finding the device in DM then it's likely there's a hardware issue with the actual device. |
First, if it's an onboard NIC, ensure it's enabled in the BIOS. If it is enabled, and the windows still can't find the device then it seems likely the device is bad and should be replaced.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
