Enable Wake-on-LAN persistent
This guide was tested on Ubuntu 22 and Debian 11/12.
Check current setting and enable manually
Firstly find out the interface on which WoL should be enabled. Therefore use ifconfig
that is shipped with the net-tools
-package on Debian/Ubuntu:
ifconfig
Your output may look like this:
enp1s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.0.2 netmask 255.255.255.0 broadcast 192.168.0.255 inet6 fe80::ed26:e33:5d38:2468 prefixlen 64 scopeid 0x20<link> ether xx:xx:xx:xx:xx:xx txqueuelen 1000 (Ethernet) RX packets 138808 bytes 178312866 (178.3 MB) RX errors 0 dropped 3324 overruns 0 frame 0 TX packets 70435 bytes 59140948 (59.1 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 [...] wlp2s0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500 ether xx:xx:xx:xx:xx:xx txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
Then check the current Wake-on-LAN-state with ethtool
. (Package to install has the same name):
sudo apt install ethtool
ethtool <interface>
Replace <interface>
for examle with enp1s0
, if this is the ID of your interface.
The output may now look like this:
Important are the following lines:
[...] Supports Wake-on: pumbg Wake-on: d [...]
If the line Supports Wake-on:
contains g
, then Wake-on-LAN ist supported.
If the line Wake-on:
already says Wake-on: g
, then WoL is already enabled, if not, you can enable it with:
sudo ethtool -s <interface> wol g
Enable automatically at boot
