Just Bought a new AC wireless PCIe card, and after install all it will do is 2 Mbps... I have a half dozen other devices in my house that can pull 30-70 Mbps from my router. I can not figure out the problem. My computer is an asus Crosshair V Formula Z Mobo, with AMD FX8370e running Windows 8.1. I installed the drivers from the disk that came with it, and then I tried the drivers from the Gigabyte website. I love the Bluetooth, but if this thing is stuck this slow I am going to send it back. Any suggestions are great. I have already tried different antennae placement, moving the router into a closer room, adjusting settings... I am at a loss
