CHECK THE DEVICES WHICH CONNECTED IN THE SAME NETWORK

WakeMeOnLan which scans the network and gives the connected devices details like MAC address and IP address. WakeMeOnLan is a simple tool which enables you to turn on sleeping networked computers by sending them a Wake-on-LAN packet. When you first launch the program it'll scan your wired network (it can't be used with wifi), collecting the network name, MAC addresses and other details of everything it finds. Which makes WakeMeOnLan useful as a simple network scanner.

Later, though, if a network PC has been turned off or is in standby, you may be able to restart it by selecting the system in WakeMeOnLan and clicking the "Wake" button.
