Forgivge me, but are you sure this is about StrokeIt? What exactly do you mean by the "StrokeIt menu in the taskbar"? StrokeIt has an icon in the system tray but it has no menu; and in any case StrokeIt has nothing to do with your wireless network connection.
Do you have a Dell notebook perhaps? Was it the Dell Wireless LAN utility? That has an "enable radio" checkbox...
