That would be an extraordinary achievement were it possible, but power lines ultimately are not connected to data lines, so such a “common” path does not exist. In theory you could hack a WiFi system and ”shut it down” or perhaps “crash” its power supply (though exactly how that could be done is not clear).
Were it possible to remotely shut down that power supply, it would make no difference to the avionics, which have multiple backup systems. On board WiFi and entertainment systems do not. When either of them fall over, which occasionally happens, the system has to be rebooted. If it stays failed, then you fly without entertainment or WiFi.
Imagine a scenario where you park outside your neighbor’s house, hack into his WiFi network, and start up the motorbike in the garage.
