WiFi
Whether the WiFi radio is enabled or disabled.
This action is ignored when Airplane Mode is on prior to Android 2.0. It also has no effect when a Wifi Tether (Hotspot) is enabled.
Note: it's not usually advisable to use the Toggle setting when also using a Wifi Near state with Enable Wifi checked, since the action will then have different effects dependent on whether wifi has already been auto-enabled for a wifi scan or not.
