Having searched extensively about this issue I find many people who are having the opposite problem, they're connected to their wireless network but can't connect to the Internet. Haven't been able to find information on how to connect a machine to a wireless network and keep it from connecting to the Internet. Just got a nice Asus wireless router, RT-N66 and thought I'd see if any of you might know a way to configure the router and the XP machines so I can share printing and files but not have the XP machines exposed to the Internet. Thanks.
