Wake On Lan only works when computer is turned off

I can turn on my computer with WOL, but I can't wake it up when Arch suspended my computer. Did I do something wrong?

I don't think WOL supports waking from standby.

It is. It works on Solus

It might be possible to look up the pci id of your network card with lspci and then enable it in /proc/acpi/wakeup.

I too can confirm WOL will wake up a system from standby.  Not sure about a laptop and if something else like lid status might affect it.

Re: Wake On Lan only works when computer is turned off

Not sure if this works as I think, but:

Maybe there is a difference how Your motherboard/network card acts in S3 (suspend) and S4 (hibernate) states?

Try if it wakes with WOL after

#systemctl suspend

or

#systemctl hibernate
