Wake On Lan problem - my computer can't be turned on with magic packet

Hi,
I can't enable wake on lan on my computer.
First I tried with an on board LAN cart then I added external cart - Intel(R) PRO/1000 GT.
In the device manager I checked "Allow this device to wake up the computer" and "Only allow a magic packed to wake up the computer" for the network adapter.
In BIOS I enabled the PME Event Wake up property.

On my machine I installed a Magic Packect sender/receiver to check whather the packets can reach the computer and I see that the packets are received when I send them from my phone.
But when the computer is turned off I can't wake it this way. Also there's light from my LAN cart, so I assume that is has power from the mainboard when the computer is turned off.
My mainboard is Gigabyte GA-MA770T-UD3 and the operating system is Windows 7 32bit.

Any help will be greatly appreciated

Not sure if it's always that way, but if the computer is turned off, Wake on LAN doesn't works. You need to hibernate or sleep it instead, and the it will resume normally.

Also, is your phone connected though the local network? Like sharing a router and entering by normal WLAN? If not, if you're using internet access to send the magic packet, you have to forward port 9 (by default) on your router.

Hi,
Thank you for your answer.
Wake on LAN should work when the computer is turned off. I'm quite sure of that. But may be my matherboard doesn't support it or it requires some additional settings. I can't find enitything in the net anyway. May be some of the jumpers must be moved or something like this. I tryed everything that I found but nothing helps.
Also my rooter has port 9 redirected.
