means the rfkill output signal from the laptop is active.
Note that you might have to reset the BIOS settings to defaults after adding a modem, or the rfkill software control is disabled and the rfkill signal is permanently asserted. Unless your laptop has a hardware switch - in that case you need to flip it.
