Actually, if you're connected to the internet, you're on a network. That 255 number is a network mask (Which I've never really understood), but I believe it should be 255.255.255.0 From the run line, type cmd, click OK. From the command line, type ipconfig /all (This will give you your network settings) and post the results here.
