I have the same wireless controller in my nettop, and that works, so it should be possible for your PC to work:

What modules do you have running? Check by using the command lsmod as root user and paste the output here too.
BTW, if you're using KDE then the network manager is NetworkManager with the KDE Network Management plasmoid as the front-end.
Are you using WPA encryption? If yes, is the SSID cloaked? If yes, uncloak it and try to establish a connection.
EDIT: I just typed all that and it's working.

Aren't you lucky?!
