    I am waking my computer up by sending magic packets. But if I close UDP port 9 from windows firewall, my computers is not booting. And also, the lights on ethernet port are off.

    It looks little too strange to me. Afaik, the software firewall, windows or any operating system should be off if computer is powered off.

    Any ideas? How software firewall effects the network card while it is not running?

    Why can't I use Wake on LAN on my computer?

    I am trying to wake up my computer. Wake on LAN is enabled in that computer's BIOS – actually it's called "Resume On LAN", but it must be the same as Wake On LAN right? The computer doesn't have any operating system installed.

    I have turned the computer off (it's still plugged in of course) and I'm trying to switch it on by sending the magic packet. The problem is: It's not working.

    It's called "Wake on Lan", so does the computer have to be actually working and needs to be in standby mode? Is there no way to remotely power on the computer?

    When I run arp -a, I don't see it's there either.

    It is possible that you have to enable another BIOS setting or check the LAN card configuration

    Computer must be in standby or sleep

    Wake, in this case, means wake up from sleep.

    Suggest trying s1 or s3 sleep as some power must be running throught the NIC in order for it to receive the magic packet
