I just asked a question about running an Ethernet cable.
There is a two opening low voltage box in the area with a TV cable and a filler. I decided to run the Ethernet in place of the filler.
First problem is that the area to drill was above the basement wall, so I only had 6" of space to drill iin.
Second problem is that it is an exterior wall, full of insulation. It took me an hour to poke a wire in the new hole and find it at the box. (the box was like a standard electrical box, but the back was missing; not as minimal as it should have been.)
I taped a string to the wire and pulled it though.
I taped the Ethernet cable to the string and pulled it through.
That was the big problem. It kept getting snagged on the insulation and I was really lucky to have succeeded.
Presumably there is a better way. I mean, they get them up a full story don't they and I only went 15".
So how do you get an Ethernet cable through an exterior wall? JIt would have been much better to have taken plain cable and put the end on once it was through; can you do that?
