Hello Nash,
In this case we suggest you to contact the seller or integrator of this system since the Intel Wireless Adapters are meant to be professionally installed by Original Equipment Manufacturer (OEM) technicians on certified systems only.
I checked some information about this motherboard and even though it seems to be a legacy product now, you may try updating the BIOS:
