I've got the same issue with a new out of the box Elitepad 900 but I dont think its a hardware issue I think its software as you can unistall, Reboot install the driver and the wifi will work whilst the device is left on however if you reboot again the wifi disappears from Windows 8.1.
The device is still there but you cant toggle it in the wifi menu or see it on an ipconfig....

This may or may not be of any help but I found when replacing WLAN adapters that I have to pull the battery plug out of the main board. If I try to switch a WLAN adapter while the battery is still plugged in then it won't register the new adapter at all, even after a reboot.
Hope that helps!
