Interesting to not see N listed. 
B and G modes are only supported on 2.4Ghz and A was supported on 2.4Ghz and 5Ghz however was dropped from 2.4Ghz a while back.
I recommend that you phone contact your regional D-Link support office and ask for help and information regarding this. We find that phone contact has better immediate results over using email.
Let us know how it goes please.
tried regional support.
tldr they sucks, and driver from regional site isn't working, had to use US latest driver
EDIT:
latest results after forcing Win1064 latest US drivers on my PC
