  1. What operating system are you running, I recommend you go to the Dell website and look for the Ethernet Drivers.

    Good luck
  2. Have you installed the LAN driver? Same thoughts.
  3. On your Dell, unless somebody has added a separate one, the NIC is built into the motherboard and is non-removable. If a separate one has been installed, it could be found in a PCI or PCI Express slot on the board.

    If you are using a wireless card, the computer will see it as a NIC also.
