Note
If the LED for the WLAN port is not green when the device starts up, although it is activated,
the port is not ready for operation (interface not initialized).
The main reason for this is usually that during commissioning of the SCALANCE W78x
products, a waiting time of up to 15 minutes can occur when the ambient temperature is
below zero. The device is ready for operation at the specified ambient temperature as soon
as the LED for the WLAN interface is lit green.
