Question

How can I determine which network adapter (NIC) I am using?

Answer

Open your network connections

• Hold down the Windows Key (to left of space bar) and press the R key
  This opens the Run or Open prompt
  
• Enter NCPA.CPL and hit the enter key
  You should now see all of your network connections

Determine which adapter you are using

• Unplug the Ethernet cable you are using at the PC
  One of the adapters will show a Red X or a notice of limited/no connectivity
  
• Plug the cable back in
  If it removes the Red X or notice, you have identified the adapter you are using
