Having problems with your HP Media Center m7250n (ED842AA) PC Desktop ?

Eathernet no longer works but connecting through USB works fine. How can I tell if it is a card or just a driver?


Answers :

If ethernet previously worked with this card and driver, issue is not the driver unless it has become corrupted.  In device manager, uninstall ethernet card and then reinstall with driver (assuming you have it).  If card does not work with reinstalled driver, odds are you fried the card.

You could try the card in another computer if you have one.  In the meantime try another ethernet card if available.
