I'm using a Litebook Intel Laptop. I had connected to the wifi and was updating the drivers in it. It required me to restart it, and I did.. when I turned it on, it showed that square with the red X, saying No connections are available.
You need to mention the make and model of your laptop. Are you sure you're not referring to the HP EliteBook? If not Then please pass on the SKU to your Litebook. We can work our way from there in trying to locate the right drivers for your networking adapters.
