in your control panel (configuratiescherm) there is an option network connections. (netwerkverbindingen)
There you can see all the connections and their status...so if they are connected or not.
Keep the internet conn. alive of course...the rest, such as a 1394 connection you can disable by clicking the right mouse button.
I only have 2 connections there, my internet connection and my lan-connection. I've turned the lan-connection off now so i'll give it a try
