Hi,
I appreciate the good explanation done by su airodump-ng -c ryan.
As clearly mentioned by him, we need to know the model number of your computer to install the required driver. You may check the Model number either from the manual that comes along with the system when it was purchased or check for it at the tower of the Computer.
Once you have the System Model Number, go to the intel website given below, select the product and download the required system file.

This should work.
