New home owner. I need to wire some ethernet and coax across the basement up into to the first floor wall. The perimeter wall is cinderblock, it is a twin and this is the shared wall. It looks framed. I believe I would want to go up through the sole plate? of the framed wall but there are two joists that run lengthwise across the basement that I can't get through very easily, there is a very little crack in the back of it I can scope up and can see what I believe is the first floor and not the sole plate.
Can I drill an angled hole through these joists and up into the wall behind the drywall or should I be worried about the structural integrity? Can I reinforce them? Looking for options.
