Have one computer running behind a D-link DI-804HV wirred router, can a D-link DI-784 wireless router be connected to the wired router to connect/feed a second computer running wireless, as for more security for the main computer? Or would this be too messy for the second computer? If not too messy will the wireless router have to be set-up by it's self on the main computer, then the wired router connected back to the main computer then the wireless router connected to the wired router to feed the second computer? Or will this cut down too much from the cable 5 Mbs main cable line/feed?
