I recently purchased this devise in hopes to go from a 4-port router (Netgear RP114) to an 8-port (Netgear FVS318). My problem is that when I swap routers, I get no connectivity. When I switch back, and reset everything, I get connectivty again. Can someone please post a detailed walkthrough in setting up either both routers, or the FVS318, so I can have connectivity on up to 8 PCs? If its even possible.
