•Try inserting the network card in another slot. If the new position works, the original slot in your system may be defective.
•Replace the failed network card with one that is known to work properly. If the second card works in the slot where the first one failed, the original card is probably defective.
•Install the network card in another functioning system and run the tests again. If the card passed the tests in the new system, the original system may be defective.
•Remove all other network cards from the system and run the tests again. If the card passes the tests, the other cards might be causing conflict.
