You need to have the card inserted before you configure and make ndiswrapper, not after. You state that after running ndiswrapper -l the drivers are present. Is it saying "hardware present" as well? If not then its a hardware problem ie. If you have hotplugging installed then Fedora will show the card in your hardware list. If its there then you need to run through a ndiswrapper uninstall
procedure and then run through the whole install procedure again, making sureyour hardware is installed.
Hope this helps
