I am trying to use the CCTK to disable the wireless on all my company's field laptops. I see there is a "cctk.exe --wirelessdevice=disable" option in the readme, but when I try to use it on any of our laptop models (Latitude D520, D530, E5400), I get a message stating the following:

The option 'wirelessdevice' is not available or cannot be configured through software.

I tried updating the BIOS to the latest version on the E5400 to A15, but it didn't help.
