I have an outlet that is only getting 100Mbps instead of 1Gbps which it is setup to get. Im sure it is the cable and one or more of the wires has something wrong with it because Cat 5e cable running Gig uses all 4 pairs of wires so if a wire has something wrong with it, it will only run at 100Mb. What I want to know is, does anyone know I could easily test to see what wire in the cable could be causing the trouble? I have a toner but that wont do me any good if im only testing 1 of the wires. Any suggestions?
