Network cables might fail unexpectedly without warning, causing sudden disruptions.
I've been employing Devolo Magic 2 powerline adapters for several months without any issues. Suddenly, my Ethernet link through the adapters stopped functioning, and the Devolo interface didn't recognize either device, prompting me to connect the PC to one of their products or verify my Ethernet connection. This issue appeared abruptly—about six hours ago, before bedtime—and everything was normal then. After turning on my desktop PC's Wi-Fi adapter, the cockpit software re-established the powerline setup and confirmed proper operation. I inspected both adapters; they both displayed a clear white LED, confirming a stable signal between them. My router is active, and I can browse the web from my desktop, laptop, and mobile phone via Wi-Fi. I tested the Ethernet cable connections on both ends and even reinserted it between the PC and the adapter. The mainboard's adapter appears to be functioning correctly, with its LED lit. My only guess is that the network cable linking my PC to the powerline adapter might have failed overnight. I turned off my PC completely before going to bed last night, but I can't explain how this could cause such a persistent problem. Unfortunately, I don’t have a spare Ethernet cable to test for wear. Given that the cable is only six months old and came with the adapters, it seems possible a new LAN cable simply stopped working unexpectedly. Anyone have any suggestions?
They might face damage from stepping on them, corrosion, pulling force, or any condition that weakens a wire segment. Ethernet cables are frequently produced with minimal expense, which often means they’re less durable. I’ve encountered (somewhat outdated) network cables that weren’t actual wires but rather layers resembling Mylar. Another issue unique to Ethernet is its four twisted pairs design; the twisting enhances signal transmission via magnetic fields. Certain Ethernet variants come with shielding, though many lack it, making them prone to interference. Regarding powerline communication, do you mean PoE? I’d check it by using a multimeter to measure resistance. PoE behaves oddly—it can operate across various voltages and is DC, leading to voltage drops over distance. If the wiring is sound, the problem likely lies with the connectors or the source injecting power. Edited November 30, 2022 by Bombastinator
It's improbable, but possible. Perhaps the issue arose from warm air escaping through a vent and disrupted a connection or introduced a new defect from the factory. Maybe electron movement caused a break, or perhaps some mischievous pixies altered your cable. Could it be that we stepped into a different reality?
It’s 10base2, right? The issue is it gets damaged by objects it wasn’t built to handle. It depends on following electrical standards to work, so any mistakes with cartoon elements could cause trouble. Homes with older knob-and-tube wiring usually won’t support it. You’re counting on a contractor who might be long gone, and a wiring setup that wasn’t meant for this kind of use. Anything could go wrong.
However, in this instance the component performed well since both connectors were transmitting clearly over WiFi and communication remained smooth.
