Tired of Ethernet cables that are too long, too short, or have clips that snap off the second you look at them? Same. So in this video, I’ll show you how to make your own custom-length Ethernet cables using RJ45 connectors, a crimping tool, and a simple network cable tester. Whether you’re cleaning up a messy home network, wiring a new office, or just sick of dealing with tangled patch cables, this step-by-step guide will bring some much-needed serenity to your setup.

We’ll cover:
✔️ Cat5e and Cat6 (and why the method is exactly the same)
✔️ Why passthrough RJ45 connectors are the only sane way to crimp cables
✔️ Stripping the cable, untwisting pairs, and prepping the wires
✔️ Using the T568B wiring standard (or matching whatever’s on the other end)
✔️ Crimping the connector and getting that ✨beautiful✨ click
✔️ Testing your cable with a cheap network tester (and what the lights actually mean)

If you’ve never crimped your own Ethernet cable before, don’t worry—it’s easier than you think, way cheaper than buying pre-made cables, and extremely satisfying. And with a basic crimper kit you can get online for around $25, you’ll be fixing and customizing cables for the rest of your networking life.
