Wake-up PC with Magic Packet

WakeOnLanTool enables you to remotely power on computers within your network by sending a so-called Magic Packet. This special network message is used to signal a powered-down or sleeping PC to wake up. In order to successfully send the Magic Packet, the MAC address of the target computer must be provided, as it uniquely identifies the network interface. If the computer you want to wake up is located in a different IP subnet than the sender, you must also specify the correct broadcast address so that the Magic Packet can be properly routed to the target network.

Please note that not all Windows computers are configured to support Wake-On-LAN by default. Some system and BIOS/UEFI settings may need to be adjusted before the feature works correctly. For detailed instructions on how to prepare your computers and network for Wake-On-LAN, please refer to the following article: Wake On Lan Windows 11.


How it works

When WakeOnLanTool.exe is started, the user can select his/her own PC from a list and then wake it up. WakeOnLanTool remembers the last woken PC, so that it is already preset when it is started again. The user is also able to ping his machine and to establish a Remote Desktop connection.

Data source

The computers.txt file serves as the data source. The position of this file can be set in the WakeOnLanTool.ini file. The computers that are to appear in the selection list (ComboBox) must be listed here in the following syntax:

Computername <Tab> Mac address

Example:

PC2065    000b9733207e
PC2066    000a9733219c
NB0680    000a977d81cc
NB0682    000a977d61a8
VD0351    000a977d91c1
VD0352    000a977d94c2
VD0356    000a977dc3af
...

You can create this list by exporting your DHCP database, for example. Most companies have other data sources for assigning computer names to Mac addresses, for example the CMDB (Configuration Management Database).

Wake-up across subnet boundaries

Most routers are not configured by default to allow wake-on-lan packets to pass. Read here how to solve this problem: Wake-On-Lan to other subnet. There you will find step-by-step instructions for Cisco and HPE Aruba routers.

System requirements

WakeOnLanTool runs on Windows 7/8/10/11 and Server 2012/2016/2019/2022/2025 (32 or 64 bit). It requires at least .NET Framework 4.
