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 W784-1xx /
W74x-1 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.
