Wake On LAN (WoL) - HP T620 + DietPi - how to enable it permanently on interface?

Troubleshooting

Hi,

I’m trying to enable Wake On LAN on my PC HP T620 where I have installed DietPi. I enabled it in BIOS and I know it is working - WoL works when Windows 10 is installed.

I can see that WoL feature is available on interface, but it is disabled:

ot@DietPi:~# ethtool eth0
Settings for eth0:

I can change it manually:

But after restart, it comes back do default value where it is dsiabled:

Is there any script that changes this setting to disabled before system is restarted / shut down?

How to make this change permanent?

I tried to follow steps from here Wake-on-LAN - ArchWiki but it didn’t work for me…

Cheers,

Hi,
dietpi is based on debian and uses ifupdown, so use debian wiki.

Thank you pulpe! I followed the instructions:

Add an interface config file /etc/network/interfaces.d/eth0 :

auto eth0
iface eth0 inet dhcp
ethernet-wol g

Activate it:

sudo reboot

And WoL started to work :slight_smile:

Cheers,
Przemek

eth0 interface should be defined within /etc/network/interfaces already. Hope it is not causing any conflict now.

As of now it is working fine and I don’t see any issues - DHCP is working, WoL is working :slight_smile:
