Not quite true, it also matters whether the pairs are swallowed to star standard T568A or T568 B; if there's a mismatch with the other end of the cable he may not connect properly.

This one is punched down T568A! I wonder if that’s standard in Finland, or if it was punched down incorrectly.
That might explain why I’m not getting a link, but I do have one broken pair just inside the wall according to the TDR.

so, i moved into my grandmas house, and found there’s ethernet ports (and one phone jack) installed throughout. it seems they all lead here. she said it was all done during the reno ~15 years ago, and she always thought they were all phone jacks.

I wonder if they use t568a or t568b. Maybe both?? Not that it matters. There are a few differences about the color of the wires and their order, but I have a visual guide of the colors in my tech folder on my phone of other visual guides. I have no problem untwisting wires and crimping them.

Apparently there are 2 different wiring schemes. The one you described is T568A, but I had to use T568B because the other end of the cable had already been terminated that way.

Wow, bold choice going with T568B instead of T568A.

One thing I've never understood. Why cable testers report "36145278" when T568A is miswired to T568B on the other end.
Wouldn't it just be the orange and green pairs screwed up?

Not all cables are equal but they're all used for data transfer which isn't the case with USB-C. Plus, the category is generally labelled on the cable. If you're worrying about wiring standards, you can just use RJ45-T568A or RJ45-T568B.
USB-C really feels messier to me.
