 Check to see if "Network-Manager" is installed.  If it is, un-install it.
 I had the same problem with my Atheros based card & no matter how much
 dickering, tweaking & whatnot, nothing seemed to work - couldn't
 establish a DHCP offer.  After removing "Network-Manager", things worked
 - I've now read that there are issues with this particular app - it
 seems to work for some & doesn't for others.

Hope this helps.

Sincerely,
