Besides disabling the option for the wireless adapter itself you may also need to modify the settings in Power Options (Control Panel), including the power plan being used.
Additionally, you can create a new package with Administrator Tool in the Intel® PROSet Software and enable PSP CAM in Adapter Settings, Power Management. The Administrator Tool needs to be selected during custom installation of the Intel® PROSet Software. You will need to run the (exe) package on the desired system once it is created.
