You'd need to download and install the driver for the adapter card and OS. The first thing is finding out what model the card you're using is and then downloading the relevant driver; but we don't know what it is as it's not mentioned.

Drivers can be packages or barebones. May be simpler to install via Device Manager (though I am making the assumption you've installed Windows), finding the adapter card and choose to install drivers that way. Choosing manual install means you can just point to the location you have the driver saved.
