Thank you all for helpful and actionable ideas. Â I’ve now got twice the bandwidth in the house that we had before, 6x in the garage loft where I hang out, and 20x in the cabin (which sucked before) where two college students will attend their Fall Semester.
To perhaps return the favor, this was the most helpful video I found for how to terminate Cat-5 cables.  I wasn’t getting it right in my first attempts (I’d even RTFM’d the package instructions), but once I watched this, all my cables have
worked.https://www.youtube.com/watch?v=rZKVPuInQ2Y
Many of you probably already know all of it, but it might prevent you from getting drafted as a cable technician by others if you can just refer them to this how-to video.
It reminds me of how I learned and how I teach soldering copper pipes – pretty detailed and a bit tedious and you *might* get away with sloppier technique, but I NEVER have leaks and that’s worth it.
