"My mistake, the -contrlwlanradio function in CCTK 2.0.1 is updated but requires a newer BIOS that should be showing up later this month. Sorry about the confusion."
"I don't have a firm date, but I hope for it to be released by the end of the August."
I tried the "cctk --controlwlanradio=enable" command on an E6410 with latest BIOS (A10) but still getting same error message as AlliGaGa reported (see below). I'm also running CCTK 2.01 & according to its documentation, the E6410 is supported
"The option 'controlwlanradio' is not available or cannot be configured
Is the Wireless Radio Control feature only available on later Dell models?
Yes, the -controlwlanradio feature is only supported on the latest laptop models.
