According on various research, this problem may come on possible situation.

1) Yes it might be on BIOS Settings, check from LAN wake up option and disabled it; this makes a retrieving operation when a data is receive thus computer would boot up itself.

2) Go to device manager and search for any related LAN drivers, go to its settings and untick "allow device to wake up the computer"

3) Scheduled updates may also be a culprit, check for any existing operation and disabled them.
