I was using Wake on Demand (not WOL) to access my mac remotely.
I was able to turn in on from LAN or internet through SSH, VNC or HTTP.
The problems came when I upgraded to Mountain Lion.
Initially It was working for a small amount of time after the computer was set to sleep: after about half an hour it wouldn't turn on.
Then, a few weeks later, as soon as it went to sleep there was no way to wake it up. I recently upgraded to Mavericks with the hope that it would have solved the problem but nothing has changed.
I tried all the possible solutions in this article but nothing helped me. In the last updates there are some workarounds but those are not what I want: they are simply keeping the mac on with the screen off, not sleeping.
Is there anyone who managed to use the real wake on demand after Mountain Lion?
Thank you.
Update:
Today, after the update 10.9.2, wake on demand suddenly started working again.

It appears this problem has been solved for the questioner by upgrading to OS X 10.9.2.
This appears to be a widely reported problem but no obvious cause or answers are documented.
