GoKawiilReport warns flat Ethernet cables are more prone to signal loss than round ones
An explainer on home networking details why flat Ethernet cables underperform compared to round ones: their wire pairs sit side by side instead of twisted together, offering less protection from interference, and they typically use thinner wire gauge, which increases electrical resistance over distance. The report also notes flat cables are often routed under rugs or doors, where bending and compression can damage the thinner wires inside.
