Pci wireless adapter problems rnx-n300x

Hello, I recently bought a rosewill rnx-n300x which is a pci express wireless adapter. Ive run into some problems though with it not being recognized at all in my device manager. The pci port is working fine and I have tried it in every single port. I also tried a variety of drivers none of which have made it work. Does anyone know how to solve this problem?

Just put your name/email in there and download. I checked up on the chipset your Wireless card uses and these are the most updated drivers for it.
