I have broadband coming in to a D-Link DI-604 Router/Gateway and one patch cable going from the D-Link to a NetGear DS-108 switch. I have 7 computers plugged into the DS-108 which uses up all the available ports. All my computers use static IP addresses. I want to add to the network another computer and a Toshiba e-Studio 550 network ready copier/printer, both of wich are configured for static IP addresses. My question is: can I use two of the three open ports on the D-Link to extend my network and will I have to change any settings in the DI-604 or the DS-108? One thing that is confusing to me is that the DI-604 distinctly says "gateway" on it (not router) byt the D-Link web site calls it a router. Does it matter for my network?
