I had a problem connecting my dad's new Samsung NC10 earlier, and I found out (after many hours) that it was a jammed Fn key that meant I couldn't type in the correct Network Key. In my struggle to get it working, I had to change the IP settings. Now I can connect with my NC10, but not my Acer (which was fine before). I have got a bubble in the RHS corner saying 'Windows - System Error There is an IP address conflict with another system on the network.'. Can someone please help?!
