miniWOL

Wake-on-LAN is a world wide networking standard protocol that basically allows your computer to be turned on remotely by a network impulse, named packet or magic packet.
This said, enabling Wake-on-LAN on your system is not that difficult: simply go to the Device Manager, find the appropriate networking device from the list, access its Properties section and, in the Advanced tab,  find the 'Wake on Magic Packet' section and change the Value to 'Enabled'.
While this is hardly a difficult task, there's an even easier way to do this with a small and lightweight piece of software, appropriately named miniWOL. In a few words, this utility makes it as simple as possible for you to send a 'packet' to a predefined server with just a few mouse clicks.

Streamlined installation and straightforward workflow

The application undergoes a streamlined installation process, subsequent to which it automatically integrates itself with your computer's taskbar. By right-clicking the app's taskbar icon, you can easily access the Settings section.
miniWOL's interface is quite functional and looks fairly good on modern versions of Windows. From the app's Settings window, which is also the only window, you can effortlessly add or remove new WoL devices. Click the designated button, type an Alias, fill in the Device Address and MAC address information, as well as the WoL Port.

Minimal set of features, actually its strong point

In terms of features, the app is not exactly stellar but that is exactly the point, to be as novice-accessible as possible. Consequently, you can perform quick Wake-on-LAN tests to see if the server is responding as it should, find the MAC address for your device and enable miniWOL to automatically launch at system startup and that is about it.
The utility automatically saves your settings and, once a device has been properly added and configured, you can send a 'magic packet' directly from the taskbar, with the minimum amount of fuss involved.

Efficient and lightweight Wake-on-LAN tool for your computer

Taking everything into consideration, if you are looking for a hassle-free application for waking up devices using the WoL protocol, then miniWOL should definitely find its way on your computer's system.
