I am sorry for the trouble. I wonder if you have any other application intended to control WiFi connectivity. There is the possibility to use Intel® Proset Wireless Connection Utility and see if the WiFi can be turned on that way; furthermore, you can run the Manual Diagnostics Tool.
You may also want to consider updating your system BIOS or contacting the motherboard manufacturer for further assistance and compatibility information. We also have to bear in mind that the installation of these adapters is subject to local regulatory approvals.
