First step is probably to makes sure the driver was installed OK: As root, type command: ndiswrapper -l to verify the Windows drivers were installed.
If that gives an error, you need to go back through ndiswrapper installation again.
Also as root, try command: iwconfig and see if it finds any wireless interfaces.
