I've setup WOL in my home pc and it works fine when I put the machine in sleep mode manually and test it connecting to it from my smartphone by tapping on the wake up button first and connecting .
However, if I wait until the machine enters sleep mode by itself after the wait period set in windows power settings, the wake up button doesn't respond waking up the remote machine anymore.
Any ideas - Thanks
A few things I would check. Did you set the power settings on your LAN and WAN adapters. Also did you turn on the WOL feature in your computers BIOS?
The last item I would wonder, because you are trying this from a mobile device. Are the tests that are successful happening when you are at home, and the ones where they are failing when you are outside of the house? If this is the case, What WOL Relay method did you choose? the IP/Port method or the one where it is forwarded from anohter TV host?
