You can obtain both the OS setting and the NIC driver setting through Relevance.
In the case of Dell Business Class hardware, you install Dell Command Monitor, and you can also check the BIOS setting through relevance. You can also configure it.
I have analyses on BigFix.me for many of these and related items.
There are some tasks to enable WOL in BigFix/IEM as well.
I believe you must have WoL enabled in the BIOS & NIC.
Also, you need at least one Wake On Lan forwarder awake in every subnet in order to do WoL to other endpoints on the same subnet.
We designate 100% of endpoints as Wake On LAN forwarders automatically. We designate “Last Man Standing” machines by hand if desired. “Last Man Standing” is a special designation for machines that should never be allowed to sleep so that they can wake sleeping machines. This is best done to an energy efficient desktop computer.
Personally I’d love to see something like a Raspberry Pi to be able to be used as a Last Man Standing, and nothing else, though Digital Signage machines are a good option as well.
