Use pass through rj45s and a Klein crimper that will also cut them. Ez pz. Anything else is an exercise in suffering.

One of the best pieces of advice that was never conveyed to me when I learned Ethernet termination: if it's a huge pain in the ass to get the wires seated correctly, try a different brand of plug.

I've had some take 15 min just to do one termination, and others where I can get 4 in the same time. Minor design tweaks make a world of difference.

Good luck, soldier.

Few potential pointers:

Initially, expose more length than you’ll need. I usually do 1 inch / 2cm

Untwist your pairs and get them loosely arranged

Pinch all the wires flat and arranged between the side of your forefinger and your thumb. Bend them back and forth, up and down, side to side, and generally “massage” them - being sure to keep them arranged - to get the kinks out. They’ll straighten out and you’ll form a new wire “memory” in your intended arrangement.

You can then cut the ends flush with one another at the intended length and you’ll have a much easier time threading them into the connector.

Crimpin ain't easy🥃💨🐙

The only part of making patch cables I reguarly have trouble with is actually getting the strands into the end before crimping. Sometimes they just wanna bend and bounce off the hole without actually going in deep enough for the thing to crimp onto. 🫩

I did this pretty much daily when working as an installer for a wireless ISP service. Usually it'd take no time at all. Other times I'd fight the damn thing for 20 minutes just getting it into the end cap.

I had about a dozen Cat 6 terminations fail to work in a row before I realized I’d grabbed the box of Cat5e tips.

Honestly just the worst when you end up not crimping down hard enough on some so they slowly come loose during use, so then you randomly start getting up but no down or vice versa
