You have inserted, re-inserted, moved, removed, or
swapped your NIC card across various PCI slots without
first removing it from the Device Manager. That's a no-
no. It results in a phantom NIC card evidenced when
another NIC is installed and is reported as Adapter #2.
The "Set DEVMGR..." along with "View Hidden Devices"
trick may not work for you. It didn't for me.
The 'phantom' NIC card wasn't really hidden. 'Non-
present' may indicate 'yanked', maybe not.
You've got half of your networking subsystem wanting to
access a now phantom card and the other half accessing
the current card in the current PCI slot.
It's going to be messy getting the extra Local Area
Connections and/or the extra Adapters cleaned out of your
registry.
I have an article that might point you in the right
direction.

I don't know if any of the various registry cleaners will
find and clean references to improperly removed hardware.
