WOL not working consistently

    I've been trying to set up WOL on a Windows 8 system and am confident that
    it's configured ok as I can confirm that the Magic Packets are getting
    through and are recognised both through the internal LAN and over the
    Internet (using a combination of Magic Packet software and TeamViewer). The
    problem comes when I shut the system down or set it to sleep or hibernate.
    Whilst I can wake it remotely for the first 20 minutes or so after this it
    doesn't respond at all. I've disabled hybrid shut-down and have read that
    WOL isn't supposedly supported in shut-down or sleep but even putting it in
    hibernate doesn't help. It's set up with dynamic DNS so I'm also confident
    that it's not due to the IP changing.

    Anyone have any suggestions or comments?

    Is the PSU maintaining standby power for the network port?
    Have you checked the correct options in the network card's Power
    Management settings?

    The green light is on when the computer is off so presumably yes it is
    Management settings?

    "Allow this device to wake the computer" is selected
    "Allow the computer to turn off this device to save power" is selected (is
    that right?)
    "Only allow a magic packet to wake the computer" is selected.

    Can't see a problem here - is there anything in Power Management might
    inhibit it?

    Wouldn't think so. If it's been turned off to save power how is it
    going to wake up except by re-application of power? It ain't goning to
    see any signal on the wire.

    If it's on even when the machine doesn't respond then that doesn't seem
    to be the problem.
    I'd be inclined to switch that one off, but I'm only guessing and I
    don't have a Windows 8 machine to play with.

    In the router's configuration, as well as the port forwarding you may
    have done, You might need to _statically_ assign the MAC address of the
    PC's network card to the IP address used for it. This normally has to be
    done in CLI, overturning the dynamic assign which is forgotton a time
    after the PC powers off.

    Which router?

    It's a Thomson TG587n v2 i.e. an O2 router (I know I've also posted a
    question about a TalkTalk router but that's a different story.....)

    Cheers Adrian. I've seen this and used it to successfully set my router to
    forward on the packets and I can see that the packets are getting through
    even from the internet. What is happening though is that after the computer
    has been 'asleep', powered down or 'hibernating' for longer than around 20
    minutes it doesn't reboot when the magic packet is sent. It's like it's only
    dozing initially and then something further powers off after 20 minutes and
    stops it from rebooting.....

    So you've done the arpadd stuff?

    e.g. arpadd intf=LocalNetwork ip= hwaddr=00:00:48:8f:03:9a

    Hmmm... me confused.

    Look at network card properties, advanced tab - there may be other
    settings there. Wake from power off, hybernate, sleep are all a
    minefield of known compatibility snags existing between BIOS, APM/APCI
    and OS. On some plaforms (e.g. HP Microserver) only wake from power off
    is properly supported.

    I've even come across slightly different implementions of the magic
    packet and differing port numbers. In windows powercfg.exe reveals a lot
    on current settings, and so does wireshark if you do some sniffing.
