Sorry to bother everyone with this stupid question, but I haven't found an answer yet. Using the DS or DS lite, it turns wlan on or off automatically, when needed. Now with the DSi I can turn WLAN on or off manually. Does this mean it uses power for wlan all the time? Or is 'on' simply the same status which the DS & lite have and turning wlan off is a mode for airplanes etc, so no game can turn on WLAN?
