I have a cat6 wired home network and have been trying to replace the jack for one of the cables but there seem to be an issue. When I use the cable tester, I see this sequence:
1, 2, 3, 4, 5, 6&8, 7, 6&8. I tried redoing it many times and I keep getting the same result. I am guessing there is a short circuit somewhere, but not sure how the coloured cables map to the LEDs. With T568B setup, is there a standard mapping to the coloured cables that I can use to figure out which two cables are short circuiting? I can keep removing the cables 1 by 1 and add them back, but there is not much cable left outside of the wall so I do not want to keep cutting them out.
