I am interested in setting up a sharing network using a sprint wireless card. Sprint says that I can buy a router with either a pcmcia card or a usb wirless card either one will work depending on the router. Now here is my question, I have seven networked cables ending in one room from all other rooms. I would like to hook a router up using the seven cables and then plug in my wireless card into the router( either the usb or pcmcia card) allowing all computers (up to 3 at a time) to run off of one wireless card..Can this be done and what type of router will I need. Can I use a hub in one port with a rj45 to expand the router.
