I know there are thousands of threads that have fixes to this but none match my circumstances

I have a Dell Dimension 4550 and I am trying to install this wireless card into Ubuntu 9.10.
When I open ndisgtk after I have installed the driver it gives me the message "Unable to see if hardware is present.", but after I press ok, it shows the driver and the status "hardware present: yes" underneath it. For any help, thanks in advance.
