I have a Lenovo ThinkPad T440p with the Intel Dual Band Wireless-AC 7260 which supports WoWLAN, but for some reason I am unable to wake my computer using wireless.
Wake on LAN through the ethernet connection in both sleep and hibernation modes works just fine. The problem is only with wireless. I do have everything checked below as you can see, just like with my Gigabit ethernet card. This is on Windows 10, I never tried it on Windows 8 so I don't know if it would have worked in the past or not. I have the latest drivers installed as well.
