Hi, I know I may post here wrongly but please bear with me, because I don't know where else I can get help. My question is how to make a Giga Ethernet network wiring. I know from Internet there are diagrams for cable but I want to know the wiring of the module (the plastic box that I insert the LAN cable. I house has a "CAT 5" cable laid, but it is only "half connected" because I found there are 4 wires unconnected. This is what the wiring when view from the rear (with the notch at the bottom). Green - White - - Orange - White The 4 wires unconnected are (blue,white) and (orange white). The colors inside () means they are twisted pair. So in order I can use Giga Ethernet, how should I wire the unconnected wires? My 2nd question is is the wring symmetrical? The above module is what I see at A end of my house, so I wonder if the B end is the same? My 3rd question is should I make a straight or crossed cable? The A end is to be connected to a Giga Ethernet Switch, where the B end is connected to an AIrport Extreme via a LAN cable Thank you very much.
