I need better internet in my basement because work forces me to work from home half time. I have spotty wifi at one end but really need to work at the other.

So, the quick and dirty way is to buy a premade "patch cord" from the big box, go out a window on the ground floor where my cable router is, and drill a hole in the concrete block wall to get it in the basement. The local stores have half inch masonry bits - can I get the connector through a half inch hole? And why does a premade CAT 6 patch cable cost less than bulk cable in 5e or 6, even without connectors? I'll do that if I have to.

But I'd rather do it right, which is to go up into the attic and back down in the basement. How in the heck do I fish a wire into the basement? This is not obvious. But I know some of you do it routinely.

The real way this is done in a commercial environment is you run the
CAT 5/6 cable and terminate it in keystone connectors in a shallow
handy box with a plate on it. No special crimpers and the hole can be
1/4" or so. Then you can use premade patch cables for the connection
to the machines. You have about 100 meters of total cable you can run
so you take the path of least resistance not necessarily the shortest
one. Getting an RJ45 through a half inch hole probably is not going to
work for you. If I really need to do it I punch a 9/16 or 5/8 but I
usually do it right and terminate in keystones.
