NetworkManager

In version 1.0.6 NetworkManager adds Wake-on-LAN controls. One way to enable Wake-on-LAN by magic packet is through nmcli.

First, search for the name of the wired connection:

# nmcli con show

NAME    UUID                                  TYPE            DEVICE
wired1  612e300a-c047-4adb-91e2-12ea7bfe214e  802-3-ethernet  enp0s25 

By following, one can view current status of Wake-on-LAN settings:

# nmcli c show "wired1" | grep 802-3-ethernet.wake-on-lan

802-3-ethernet.wake-on-lan:             default
802-3-ethernet.wake-on-lan-password:    --

Enable Wake-on-LAN by magic packet on that connection:

# nmcli c modify "wired1" 802-3-ethernet.wake-on-lan magic

Then reboot, possibly two times. To disable Wake-on-Lan, substitute magic with ignore. From version 1.2.0 Wake-on-LAN settings can be changed graphically using nm-connection-editor.

When using TLP for suspend/hibernate, the WOL_DISABLE setting should be set to N in /etc/default/tlp to allow resuming the computer with WoL.
