This API is available on Firefox OS for internal applications only.
Summary
The enabled property value indicates whether the wifi is turned on (true) or off (false).
Note: Enabling or disabling WiFi can only been done by using the Settings API to change the wifi.enabled setting. Each time this setting changes, the WifiManager object will send an enabled or disabled event. Those events can be handled by using the WifiManager.onenabled and WifiManager.ondisabled event handlers.
