When configuring the Power Management options on an adapter, be it wired or wireless, there are traditionally three checkboxes available:
Allow the computer to turn off this device to save power Allow this device to wake the computer Only allow a magic packet to wake the computer
On the older hardware, all three checkboxes are present and all three can be configured.
On the newer hardware however, only the first two checkboxes are present and only the first can be checked; the second is completely grayed out.
This isn't some visual glitch or odd GUI limitation:
All machines are fully up to date from TVSU and we even pulled not just the drivers but also the Intel PROset suite directly from the Intel site but that didn't change anything.
That said, all of this almost looks like a 'regression', but the root cause is not known:
So why are we missing an option and why is the second option grayed out?

How do you expect to use the wireless adapter to wake the system if it is asleep...? That assumes a disconnected (not wired) computer, monitoring "the airwaves" for information directing it to wake. While it is in a suspended state...with the wifi card off...
Note that WIRED WOL capabilities are still part of the machine...if you allow it.
Waking a system from a sleep state is possible if you have full Intel AMT capabilities for Wake via wireless properly configured on an AMT aware management console AND the system....a rare deployment situation. And rather tricky to configure. VERY tricky.

Hey rbkirk and thanks for the response.
Your response, while greatly appreciated, doesn't answer the core questions:
However you have a solid a golden nugget in there: Are you suggesting that WoWLAN is *only* (i.e.: exclusively) supported in environments where AMT is enabled & configured specifically for Wake on Wireless LAN?
"How do you expect to use the wireless adapter to wake the system if it is asleep..."
Not having used/tested this before, it seems like a real thing:
But I just want to be clear: My goal is to understand why the Power Management options are different.
I'm not here to focus on what's involved to get WoWLAN setup & working; that might be a separate thread.
Many thanks again.
