Yes, that is your wireless card. As it is an Atheros card, it should be 
supported by the madwifi driver, not by ndiswrapper. Check if you have 
package "linux-restricted-modules" installed. The madwifi driver is part 
of that package. If you have the package installed, use the command

sudo modprobe ath_pci

in a terminal. I don't know if there is any output already about your 
card. If there isn't, type the command


and see if there is something mentioned about your card at the end. If 
your card is supported, you should find an interface ath0 with the 

ifconfig -a

If it isn't supported, you would have to compile the driver from source. 
Here <https://help.ubuntu.com/community/WifiDocs/Driver/Madwifi> you can 
find instructions if that would be necessary.
