Since you already ran a new cable, this is more for other people who stumble in here unless you still want to try to make it work...

Since you're talking about a new house, hopefully all the wiring inside the house terminates in the house. You'd hope to see some wires from this location to the box outside the house.

If you're having a problem with network wiring in a house the main things you need to look at are:
  • Where does the wire go?
  • What is it connected to?
  • How is it terminated?
  • What type of wire was used?

Sometimes you'll see Cat-5e wire run for phone lines, but instead of running all the wires to a central location they daisy chain one phone outlet off another. Sometimes they home run all the wires, but run them outside to the phone DEMARC box. In both of these scenarios it's hard to use the wires for networking. Sometimes they run it to a central location but punch everything down on a block that connects all the wires of the same color together for phone, you can use this for data but have to disconnect and re-terminate the wires you want to use.

The use and allocation of twisted pair wires in an Cat5+ cable isn't arbitrary. If the cable isn't terminated according to T569B (or A) on both ends it won't work. Don't mix A and B, B is generally used for data.

There have been many similar threads over the years and unscrewing wall plates and taking pictures is almost always required to sort out what's going on.

To add to jkee's post:

A lot of times the cables will be run back to the Master Bedroom Closet and terminate there.

+1 on pulling ALL the face plates off where you can find Jacks and mark them down on a hand-drawn floor plan of the house.
Look at the cable, there *MAY* be a number or letter written on it with a sharpie, note that down as well.

Chalk it up to the adage.... an ounce of prevention (labeling on install) is worth a pound of cure (trying to figure it out after the fact). Seems very poor workmanship, to me, to pull data/pots/rg6/etc and not at least label them, let alone do it properly (home runs to a central location). That's like accepting workmanship from an electrician that willy-nilly runs power to all the outlets on one floor to a couple unlabeled breakers in the panel.

This is a situation when a cable toner is absolutely invaluable. If you ask around, you may find someone willing to loan you one.

My cousin had a house built last year. All the rooms had ethernet ports and wires running to the network closet. The technician only hooked up what they wanted, leaving all the other cables behind the panel. Short of pulling the panel, not sure if they even put the male connectors on the cables.

thanks for the help guys.i tried 3 different cat5e cables from inside the house.they were on the wallplate along with coax connection.outside box had all the wiring,couple of coax connectors,three cat5e connectors and one phone line connection.didnt want to troubleshoot anymore so i just ran a ubiquiti cat5 wire along the bottom to the garage.seems like the ubiquiti wire is higher grade compared to the one installed in the house.the five wires cat5e was super thin.

FYI, Overall size of the cable can vary from manufacturer, but they have to meet the standard for 5e, etc...

What can kill a good cable is a crappy installation. Stapling the wires in the wall, etc... will deform the cable and degrade the performance significantly with just 1 bad staple.
We had to use rated supports that didn't put undue bends on the cable as well as several other things for the physical installation.
In a commercial building, it was the norm to just run the cable on top of the false ceiling, but the grid every 2 to 4 feet would put a sharp bend in the cable, so you couldn't do that. Then it was a bridal split ring hanging from the structural ceiling that also put a bend in the bottom cables in the bundle, so that gave way to a rated J-Hook that had a nice rounded sweep so the bottom cables didn't get mashed...and that was when it was just Cat 5 not the higher 5e rating.


I don't blame you for just running your own cable vs. trying to troubleshoot as that can be very frustrating to do.

Cat-6 is generally much thicker than Cat-5e as most Cat-6 has a plastic spline in the middle. A lot of Cat-6 is also slightly heavier wire.
