I don't understand the point of the mini PCIe slot if it isn't actually PCIe. It's just a USB port diverted to a mini PCIe slot that can only be used with specific wifi modules. It even disables one of your USB ports when in use. Why not just use the USB port for WiFi

Good one.

I purchased this motherboard for build and it has worked great.I matched it with an I7 8700 and 16 gb of ram and everything works great.
