Problem with cat5e

By laf0705 ·
Ok, here is my problem. I recently dropped a cat5e cable from a home office to my family room. I used wall plates at either end and have tested the connection which has signal accross all eight strands. Now, I use a patch cable from my router in the office to the wall plate, and a second patch cable from the other wall plate to my laptop.

Will not work. The computer knows something is plugged in and it shows 4 - 6 packets received, but nothing sent.

I tried using both patch cables directly to the router and they both work. The run is only 45'. None of the cables are crossover.
I'm as a loss, any ideas, thanks.

How did you terminate it?

by ThumbsUp2 In reply to Problem with cat5e

Did you cross any strands in the one in the wall, or is it straight through to each end? If crossed, you've essentially got a tripple cross, one on each patch cable and one in the wall.

So, what's in the wall and how's it terminated at each end?

straight through

From plate to plate it's straight through

Might Need 1 Cross

by TheChas In reply to Problem with cat5e

When I set up my home wiring, I ended up needing to cross the cable from the router to the wall jack in order to get a one to one match from my test tool.

But, I did run the cable basically as an extension cable rather than a patch bay.

Also, most of your wall RJ45 jacks do NOT run the wires across from 1 to 8 like the RJ45 plug on your cable.

So while you might have a 1 to 1 wiring, if the pairs are not properly matched you can have an impedance mismatch that will degrade the signal.
