Wake on LAN in HP Compaq Elite 8300

Hello, 

I  am trying to turn on my lab computers at a time with "Netsupport school" Software.

I unchecked " Turn on Fast startup"

I disabled " S5 Maximum Power Saving". ( I tried Enable/Disable both) 

I changed " Change "Remote Wake up Boot source" to "Remote Server" "

I checked " Allow this device to wake the computer" 

and I can't find wake on LAN option in Advance tab.

But I still not able to turn my computer on with " Netsupport school" software. I am using HP compaq Elite 8300.

Kindly do the needful.

Thank you
