Why won't my home made CAT5 cables work?
I made a 75 foot CAT5 cable with a generic ends and an RJ45 crimping tool. I used a cable tester that verified all 8 wires are aligned, but it doesn't work. I removed all other variables. I tried making 3 and 5 foot cables and they both work. What could the problem be?
I've seen a similar symptom like this that was fixed by recrimping the ends and making sure the gold teeth in the RJ45 connector had a good bite into the copper.
It's odd that your network tester isn't complaining, but it *could* be that there's enough signal for the tester, but maybe there's some inductive noise or something else causing errors on the data stream.
Be sure you don't strip off more than about half inch to an inch of the outer casing, as this helps shield the wires from noise. Also, only untwist as much wire as you need to to get them into the connector - same reason.
