minus-squareHawke@lemmy.worldlinkfedilinkarrow-up5·3 days agoBlue in the middle is pair 1. Orange around that is pair 2. Green on the left, brown to the right. CC-B-AA-B-DD. Pair A is for telephone back when Ethernet was wired to a punch down block. Pair B and C are for data. Swap b and c on one end for crossover. The fourth pair is basically useless.

minus-squaresimpleslipeagle@lemmynsfw.comlinkfedilinkEnglisharrow-up7·3 days agoUseless for 10/100. If you want gig you need the 4th pair.

Yeah but it still explains the “why?”
