I have a Linksys wrt54gs router that connects my Windows XP Pro PC to a HP DesignJet 1055CM plotter. The connection is wired between the router and the plotter. My PC is wired also to the router. I cannot successfully ping the plotter and my router has limited capability since it does not list all connected devices to the network. What must I do to get the router to recognize the plotter and what is a good software to list the IP addresses of all devices connected to the network since my router does not? Note, the plotter has an IP address in its configuration file.
