Well firstly, just to be sure that you know, LW and several other P2P applications all worked fine while still having the very same setup, although I know sometimes things can happen. Our setup is as follows: we have a main server which is directly connected to a scanner and an external burner. Then we have 2 printers and our internet which are all connected into the wireless router. The server and 3 other computers all have wireless cards to be able to access each other and the devices. Finally there's a third printer which is directly connected through my computer. Since I would have to set a static IP for every computer and then set these for the different devices to work with themselves this would take awhile and would almost certainly end with compatibility issues which I would prefer avoid alltogether. I hope this all helps and is pretty clear, just ask if something is uncertain or does not make sense.
