Run ethernet from basement to attic.
When adding or replacing wiring in finished walls most electricians will attempt to make the horizontal portion of the cable run in the unfinished attic or basement crawlspace areas looping the cable down or up through the wall cavity across the floor or ceiling joists then vertically through another stud cavity to the next wall box opening.
From inside the living space position the bit against the wall directly above if accessing from attic or below if accessing from basement the desired location of the service the cable will provide.
When necessary use existing ducts or pipe runs to get wires from the attic into the basement.
If you re working from the attic you can drop a weighted string down wall cavity then attach the wire to the string and pull it through.
For the horizontal portion of the cable run this can involve drilling holes in the joists where the cable will pass.
