Sounds to me you might need a different driver! Its not detecting your nic or doesn't know what it is. My suggestion would to be first to find out if your card is in any of the hardware compatibility lists, in which I did not find your card listed anywhere, Intel has all the drivers for most OS other than Linux or Unix. You might also want to go thru the howto's to see any other steps you might want to take, at:

This might point you in the right direction.
Hope this helps in anyway.
