[SOLVED] Wrong color coding for Ethernet cable

[KAD03]

So a few years back my dad got me an Ethernet cable to my room that improved my playing experience. I used it for PS4 and it worked great. Then I got a pc 2 years ago and that same cable didn't work with my pc. I didn't bother much because I didn't understand that stuff and I left it there. Now, when I am a bit more experienced I was wondering why doesn't it work. And I checked the cable and color coding on both sides was wrong. The standard used was T568B and green and blue were switched up. Is that the problem? But if it is how did it work on PS4?

The electrical signal does not know the color of the plastic. There are cables that have 50 pairs of wires that are used between patch panels and those obviously must be different, you would never get it right if there were only 4 basic colors.

What is key is that the pairs of wires are correct. Now if only the solid green and solid blue wire were switch it would be a issue but if both the green and the green/white were swapped with the blue-blue/white it would work fine.

Many years ago before even cat5e they made cables where the brown and blue pairs had fewer twist. I guess it was to save costs somehow. Those you had to be more careful and you still only ended up with a 100mbit cable.

Cables are really strange when they go bad. They likely no longer fully meet the specs for data transmission but some devices are more tolerant of a poor cable. Can be as simple as corrosion on one of the pins or a slightly loose connection

Only solid green and solid blue are switched up. Instead of normal T586B standard, it goes white orange, orange, white green, green, white blue, blue, white brown, brown on both ends.

That should not work on anything because you have broken the pairs. The wire pairs and the twists are used to detect a differential voltage used for signalling. If the wires are not twisted together the voltages between them can be way off and you get a all 1 bit or all 0 bit condition. If it worked at all you got lucky.

That cable pattern though is a valid one used by many digital pbx. If it is a flat cable then that is what the cable actually is.

Honestly, it doesn't matter what the colors are if actual wiring follows the correct pattern. Not sure why it doesn't work, but I would start by looking for any strains/cuts.
