My house's builders seem to have cut one of the Cat-6 internet cables somewhere along it's run from the basement to the data hub where all of the other cables converge. It might even be between the floors. This is a low voltage circuit.
The basement outlet is about 12 below and about 25 feet along a single wall from the data hub box. (The Cat-6 cable does not turn corners. It goes up and over.) I have access to the other end of the cable in the data box.
Is there a device that I can plug in to either end of the cable and then track the path of the cable from on top of the dry wall? I hate to punch a bunch of holes in the plaster when I have no idea where the cut is. If I could punch one hole, I could splice the break with a male-female connector, put it back in the wall, and patch over it.
