I have the GS. My desktop computer is connected directly to the router. I have a laptop that connects wirelessly and a PDA that connects wirelessly as well. This setup works as expected and I have no problems. Occasionally I work on other people's computer and need to plug them into the router. Generally these computers are infected with spyware, etc. To avoid infecting my other computers, I have to disable their network connections or turn the computers off. Is there a way to make it so that any computer (other than my original three) that connects to the router can not see any of the other original computers and still use the internet connection?
