|If you're connected to a network there will be activity. What happens, even when you're not using your connection, is your NIC sends out a signal to check and see if there's a network available. If it gets a repsonse it knows it's still connected. If it doesn't get a response you get the "Network uavailable" error.|
It's not a problem and is in fact necessary.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
