Hi; I've been reading other forum posts but still a bit confused. Here is a picture of the hub in my closet: http://imgur.com/a/7abk7 . My router/modem is connected in the living room to a co-ax cable in the living room. What I've attempted so far is to use a patch cord to plug the router into an ethernet port into the living room wall. Next, I hooked up my PC and tried plugging in each of the black ports in the hub; none of them gave me a connection. My plan was to find the port for the living room, then use another cable to connect that living room to the corresponding port that connects to the bedroom. What am I doing wrong? Thanks.
