Hi, I have the current networking setup for our home office (see pic) The G4 shares an external FW400 disk that is connected to the Mac Pro. The Mac Pro however is going to be replaced by a Macbook Pro laptop. While working in this room, it will be connected to the 23" ACD. So no need for wireless here. I can plug it in to the router. In another room however i want to be able to wirelessly connect to the internet, print, and have access to the external disk. What do i need to get this working? Can i keep using my router?
