Hello,
I seem to be having the same issue so I did some testing.
I just tested 2105 and 2105b and got the same results so I assume a setting or issue within 2105 is present. Neither of them seems to work on my PC from a power off state but work fine from a sleep state. Previous to 2105 I have been able to WOL after a shutdown.
I checked my BIOS settings and have the Wake from PCIe enabled. I have also checked my NIC and it is set to allow WOL.
I tested from remote and local using two different apps. I used WHS2011 Add-Inn “AWIECO WakeOnLAN” and a WOL GUI app from “Brian Slack”. Both these apps worked previous to 2105. Both the apps are able to wake all my other PCs just fine.
Is there another setting in the 2105 BIOS that we need to change besides the “Power on by PCIe”?
