In this tutorial Allan Muller explains how to detect a network change.

When building RIAs you often rely on data being downloaded when up front via the preloader which is find for getting the look and feel and some static content but when you need to display specific data which the user has input into often you need to pass data to and from web services or databases. This obviously requires an active internet connection but what happens if the users connection drops? Well in Silverlight 3 the NetworkInformation namespace was introduced which allows you to hook up an event to your application and capture when the connection is alive or dropped. In this tutorial I am going to show you how to hook up this event and also inform the user of the issue on screen.
