Ran Long CAT 5e

[TheUnk]

I ran one about 125-150' and it's not working...

The light on the port on the switch it's plugged into turns green, but only briefly, and then back off. It just continues doing this unless I unplug it from the PC.

Does that mean the cable is too long or what? If it was the wiring then wouldn't the green leds not even turn on at all?

I've redone both ends of the RJ45 jacks and it was of no help.

You probably just have it wired wrong. If it is solid core twisted pair into cat 5e jacks it will be just fine upto 90 meters. All kinds of things would cause a flaky link light like that and most all of them are cable.

Double-checking something...to be sure we are talking the same thing. I'm not intending to insult you. Just don't know how much experience you have.

At the two ends of the cable, you're connected to JACKs like those in these photos., and not to plugs? Correct?

Plugs on both ends, so it goes directly into the PC from the router.

See link ... odds are you do not have it wired properly ... Most cabling is done to 568B standards .. either will work as long as both ends are done the same way. If you are making a crossover cable then one end is 568A and the other is 568B

Also, I have found that on some very long runs that the use of a switch at both ends works better than a NIC. Check the cable them try a switch between the PC and the long run and see if that makes any difference.

Yep I didn't wire it properly. I haven't done it in a long long time. I did neither A or B. I just wired them orange, green, blue, brown, starting with the stripes first. I just assumed that as long as both ends were the same then it would work.

So the way the wires twist around eachother really cause enough interference to cause it not to work if wired differently? Really never thought about that before now..

Just buy a factory terminated patch cable and save yourself the hassle. Sure, you might get lucky and your cable might work, but unless you have a tester you can't certify your cable will work at what you expect it to, especially in a longer run.

The entire reason it does work is how the wires are twisted.
