I have a desktop (possibly 2),a laptop, and a surveillance camera that I want to network. All the hardware is linksys except the camera. It is a D-Link DCS-900W. I also have an Alphashield that goes from my cable modem to my router. One of the desktops is wireless with the potential other as a wired one (for now). I have high gain antennas and a G & B router, a G access point, a G print server, to name the core components. I want to utilize all these components in the most efficient way. I want the camera to be on a different network entirely, as well. I may get the netgear powerline range extenders soon. Can anyone help me sketch out a diagram so I can set these components up in a manner that is highly efficient? Thanks!
