2009 mac mini wireless ac adapter

I have a early 2009 mac mini with el capitan does anyone know where I can find the drivers for a dlink dwa-182 wireless ac usb adapter ver. 1? i've checked the dlink site and there are no drivers for OS X and i can't find what chipset this adapter is using, any help would be greatly appreciated. Before it gets brought up, I do have a wireless ac router,netgear nighthawk AC 1900.
