Why am I getting poor network speeds on my self crimped cables.

Looking to install IPCameras around my house.
I've been practicing howto crimp with short cable runs, and I've noticed my devices are falling back to 100/10 instead of gigabit (or I lose packets) when I use my self terminated cables.

This is the pinout I followed: https://i.pinimg.com/originals/84/eb/95 ... f1063e.jpg
Plugs: https://www.amazon.ca/dp/B07X9V97MG/
Crimp Tool/Test: https://www.primecables.ca/p-309139-cab ... rimecables

I use scissors to cut the excess wires that come out of the plug. I crimp each plug a few times to make sure I didn't miss any. The 10T tester doesn't see any problems (even under pressure)


I've watched youtube videos... I'm not sure what I'm doing wrong.

*slowly raises hand*

Are you using cables rated for gigabit? ._.

That usually happens if you crimped the cables incorrectly. Make sure split the green pair, idk why but that's something you need to do for cat5e.

Maybe not enough pressure applied on the crimp? You want to make sure the metal contacts are deep into the 8 conductor lines

how come the crimps i used did not allow the conductor to come out like yours?
I had to trim them level, make sure the outer sleeve would be squeeze in the connector before I could crimp

Those are the fancy pass through ones.

Most IP Cameras *ARE NOT* gigabit enabled. So even if you have them crimped properly the cameras don't have the technology to do gigabit even if your cables or switch can.

It's cheaper IMO to buy a large cat5e spool and just cut your own cables.

oh it is no question. But your now knee deep into why its cheaper.

Its a niche that is dependent on quality of tools,parts, and the most important factor "practice" helps most.

There is absolutely no resistance when I go to recrimp them. So they are pressed in as far as this crimper allows.
I have the green cable split.

The spare cabling that I'm practicing with is CAT6.
The cabling I plan on using for the cameras is 23awg CAT6A (I realize this is a waste, but it beats having to go buy a Cat5e spool).

I think you're right.
I thought I was getting a quality product given the price and the rating.... but I guess I was wrong.

Plus, most of the positive reviews are for the 24awg plugs, whereas I bought the 23awg.

Make sure you cut those protruding wires back flush with the plastic connector too. This can, and probably will, cause the cables to not seat properly inside the plug would could cause poor contact on the pins and also lead to slow speeds. On tighter fitting plugs, they may not fit at all.

Do you have a cable tester ? An inexpensive one is good enough ... it can detect possible individual cable issue also crimping mistakes. I strongly recommend you test every self-made cable.

10/100 only needs 2 pairs ... It is possible that there might be issues with 1 (or more) of the remaining 4 wires ... just a wild guess ...
