How to make USB Wireless Adapters work on DM6467T??

Hi, I'm new with DM6467T...

Now I have problem about using USB Wireless Adapter on DM6467T

My adapter is D-LINK DWA-140.

In my opinion, I should download the Linux driver on official site first.

so I download the driver from the Link (as bellow).

http://www.dlink.com/products/?tab=3&pid=DWA-140&rev=DWA-140_revB

After I unzip the tar file, I find there is no proper option in PLATFORM of "Makefile"...

Can someone help me to solve this problem??

Thank you very much:)
