I understand that you cannot boot your system from S5 using the wake on LAN feature.
I have not tested this myself so I will escalate your report to the testing department so that they can check if there is an issue.
Actually WOL from S5 sometimes works. After further tests, I found it depends on how the system is shut down.
If I turn off the system from desktop or by ir remote, the network adapter remains active after the system is off, and WOL from S5 works.
If I turn off the system via remote desktop, the network adapter then is deactivated (from the router, no led on the corresponding port is up), and WOL from S5 does not work.
