I need some ethernet cables between my computer room and the TV room. The
easiest way is to run the cable in the crawlspace and then up through the
floor for about 1 foot.

The plan is *to drill a hole from the crawlspace up into the space between
two inside walls (one of them is the TV room) and between two studs. Then I
can make an opening on the wall for the faceplate and the network jack.
There is an electrical outlet on that wall, but I don't think that's going
to help.

If I could drill the hole from the top between the walls and between studs,
that would be easy. But since I can't get a drill inside the walls, I have
to drill up from the crawlspace. How do you identy the area between two
drywall, from the crawlspace looking up?

just figure out where you want the jack to be and start from there.
The presence of the receptacle really doesn't help, unless the wiring
for that comes up from below as well in which case you can use that to
establish the line of the wall. *You probably don't want to have the
jack in the same stud bay as the receptacle unless there is a
compelling reason to do so.

If you have baseboard it might be helpful to remove it, drill a small
hole down through the floor that will be covered by the baseboard,
then use that as a reference to drill your real hole. *have a helper
shine a flashlight through that hole while you are in the crawl
space. *Remember that if you have a 2x4 studded wall with 5/8 drywall
the actual width of the whole wall without baseboard will be about
4-3/4".

Alternately if you have a right angle drill and a lampmaker's drill
bit you could rough cut the opening for a single gang box where you
want the jack in the wall, then use those to start the hole in one
shot (might need to shorten the lampmaker's bit so that it fits in the
wall right,) then hog it out with a spade bit from underneath. *Then
put in your low voltage ring and continue as per normal.

As an aside, I just got a brilliant idea although I don't know if it's
practical - a right angle drill with a chuck such that the lampmaker's
bit could pass completely through the head of the drill for length
adjustment, for just these kinds of jobs...

good luck!

Never heard of a lampmakers bit, got a web site for a description?

That's what I've always heard it described as, it's just basically a
really long standard split point bit. Got a couple in my toolbox that
I've been given by friends/family when cleaning out deceased
relatives' stuff, picked up for cheap at garage sales, etc. Name
makes sense to me as if you were making a lamp from scratch from a
piece of turned wood you'd need it to provide the path for the zip
cord between the base and the socket.

The special flexible electricians' bits as sold by Greenlee etc.
probably work better for the OP's application, but I don't have any of
those, and they're spendy for as often as I have an application for
them. (I did have to break down and buy some long shank spade bits
though for running wires in instances where joists were doubled or
tripled and a regular spade bit wouldn't punch all the way through in
one pass.)
