Wireshark can show you what network traffic is flowing as far it passes the network interface you capture on. If this traffic is not passing it, it can't show it. In short it can tell you the what, but not the why. Anything wrong at the physical layer (as cables and stuff are called) can't be seen. That is the domain of network drivers, etc, so totally depends on your operating system, which manages those.
