You probably do not need to install drivers for the new card. As long as the new card is fully supported in Linux, then it should work out of the box.
I performed a quick search on the Internet and I could not find a relevant post on the term
ADDON NWP210 with relation to Linux.
If there is no free driver for the card, you can install the Windows drivers with ndiswrapper. Therefore, what you can do now is install the
ndisgtk package from the Software Center and have the CD handy. If the card does not work out of the box, you have what is needed to install the Windos driver for it.
