I haven't tried the System.Net.NetworkInformation namespace on WP8. But the new WP8 Windows.Networking.Connectivity Windows Phone Runtime namespace works just fine.

Use Windows.Networking.Connectivity.NetworkInformation.NetworkStatusChanged to know when network conditions change and use Microsoft.Phone.Net.NetworkInformation.NetworkInterface properties or Windows.Networking.Connectivity.NetworkInformation properties to see what's up.

    private async void MainPage_Loaded(object sender, RoutedEventArgs e)
    {
        PrintNetworkStatus();

        NetworkInformation.NetworkStatusChanged += NetworkInformation_NetworkStatusChanged;
    }

    void NetworkInformation_NetworkStatusChanged(object sender)
    {
        PrintNetworkStatus();
    }

    private void PrintNetworkStatus()
    {
        Dispatcher.BeginInvoke(() =>
        MessageBox.Show(NetworkInterface.NetworkInterfaceType +
                        Environment.NewLine +
                        NetworkInterface.GetIsNetworkAvailable()));
    }

And once I shutdown my WiFI router and the WiFi connection on the phone is lost I see the following MessageBox:
