When using TLP for suspend/hibernate, the WOL_DISABLE setting should be set to N in /etc/tlp.conf to allow resuming the computer with WoL. Wifi.wake-on-wlan = ignore Enable WoL in TLP You can disable Wake-on-Lan for all connections permanently by adding a dedicated configuration file : The Wake-on-LAN settings can also be changed from the GUI using nm-connection-editor. To disable Wake-on-Lan, substitute magic with ignore. # nmcli c modify "wired1" 802-3-ethernet.wake-on-lan magic # nmcli c show "wired1" | grep 802-3-ethernet.wake-on-lan 802-3-ethernet.wake-on-lan: defaultĮnable Wake-on-LAN by magic packet on that connection: Wired1 612e300a-c047-4adb-91e2-12ea7bfe214e 802-3-ethernet enp0s25īy following, one can view current status of Wake-on-LAN settings: One way to enable Wake-on-LAN by magic packet is through nmcli.įirst, search for the name of the wired connection: NetworkManager provides Wake-on-LAN ethernet support. etc/netctl/ profile ExecUpPost='/usr/bin/ethtool -s interface wol g' NetworkManager If using netctl, one can make this setting persistent by adding the following the netctl profile: First, make sure cron is enabled, and then edit a crontab for the root user that contains the following /usr/bin/ethtool -s interface wol g The $name placeholder will be replaced by the value of the NAME variable for the matched device.Ī command can be run each time the computer is (re)booted using in a crontab. etc/udev/rules.d/ les ACTION="add", SUBSYSTEM="net", NAME="enp*", RUN+="/usr/bin/ethtool -s $name wol g" Otherwise, NAME would be undefined and the rule would not run. The file name is important and must start with a number between 81 and 99 so that it runs after les, which renames interfaces with predictable names. The following rule will turn on WOL on all network interfaces whose name matches enp*. Udev is capable of running any command as soon as a device is visible. This is an equivalent of previous systemd.link option, but uses a standalone systemd Īlternatively install the wol-systemd AUR package, then activate this new service by starting rvice. In the Match section, OriginalName= can also be used to identify the interface.This configuration applies only to the link-level, and is independent of network-level daemons such as NetworkManager or systemd-networkd.To be considered, the file name should alphabetically come before the default 99-default.link.The content of the default link file /usr/lib/systemd/network/99-default.link shipped with systemd has to be included, otherwise the interface might be misconfigured. Only the first matching file is is applied. The value g is required for WoL to work, if not, the following command enables the WoL feature in the driver: The Wake-on values define what activity triggers wake up: d (disabled), p (PHY activity), u (unicast activity), m (multicast activity), b (broadcast activity), a (ARP activity), and g (magic packet activity). # ethtool interface | grep Wake-on Supports Wake-on: pumbag To query this status or to change the settings, install ethtool, determine the name of the network interface, and query it using the command: Software configuration Enable WoL on the network adapterĭepending on the hardware, the network driver may have WoL switched off by default. Note that some motherboards are affected by a bug that can cause immediate or random #Wake-up after shutdown whenever the BIOS WoL feature is enabled. Look for terminology such as "PCI Power up", "Allow PCI wake up event" or "Boot from PCI/PCI-E". Different motherboard manufacturers use slightly different language for this feature. The Wake-on-LAN feature also has to be enabled in the computer's BIOS. Some wireless cards have support for Wake on Wireless (WoWLAN or WoW). The target computer has to be physically connected (with a cable) to a router or to the source computer for WoL to work properly. The target computer's motherboard and Network Interface Controller have to support Wake-on-LAN.
