For some reason you did not install the driver correctly.
This installation works, maybe you had some issues with your internet connection?
After installing the driver you have to reboot the box, after that you should be able to configure it.
You might have to set up autostart there depending on your box.
I don't even think that there's any possibility to get this wrong since it's proven for years, the only bad thing that could happen is bad internet or that you aborted the installation somehow.
