So our extra room has the router in it. I just bought a 100 foot cat5e cable to connect my Xbox to that router with a wired connection. Can I use my old belkin router (n150 I believe) to attach that Ethernet cable to the upstream port on the router, then use the downstream ports to power my laptop desktop and Xbox? My desktop and laptop are currently wirelessly connected, and the Xbox gets its Internet from the laptop Internet sharing. Also, will this cause nat issues with my Xbox because of having double routers? I do not want to use the wireless feature on the second router though. I just want a more secure connection, and a open nat on my Xbox.
