So I have installed the Dell software… then installed the wireless driver you have listed above… I am on a XPS M140 with Windows 7 currently installed and am getting no results for wireless… I do not believe there is a switch for the wireless besides the [fn] + [f2]?
Can you provide the hardware IDs?
