How to Run Ethernet Through Walls (Without Tearing Everything Open)

Most people skip straight to buying cable without ever asking how it gets from point A to point B. This episode walks through the actual infrastructure: how to find existing conduits (smurf tube, electrical raceways, HVAC cavities), what you can do yourself versus what requires a licensed pro, and how to pull cable without destroying your walls. From tone-and-probe kits to fire-rated risers, fiber vs. copper, and the one mistake that turns gigabit into 100 Mbps — this is the episode for anyone staring at a wall with a fish tape in hand.
