A basic $20 Ethernet cable tester is one of the most practical home networking tools available. About a third of accumulated cables in a typical household can fail silently, causing intermittent issues that get blamed on other things. A continuity tester quickly identifies open, shorted, or crossed pairs with no ambiguity — the cable either passes or it doesn't. While a cheap tester won't catch every possible issue, it covers the most common physical-layer problems and lets you audit your entire cable collection in an afternoon.
