Blue 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.

Thankfully I don't need to worry about that for stuff later than ~2010.

Yeah but it still explains the “why?”

Useless for 10/100. If you want gig you need the 4th pair.

So, useless for home internet, but useful if you want to use your PC VM on your laptop
