[SOLVED] Need help setting up my home network

You need to provide more specifics. What network hardware do you have? What ISP speed do you have? How much area are you trying to cover with WIFI? How many wireless devices? How many wired devices? Do you have ethernet cabling in your home? Is it a house, apartment, a boat or some other unusual "home" ? Even provide a drawing of the floorplan.
