WOL by PME doesn't work after a while

[Sandr]

Hi guys,

I succesfully set up my PC to boot on LAN, everything works just fine, but...
After powering down it only works for about an hour or so, then, nothing happens. I thought it might be because my router cleared the routing table, but I set up DHCP for a static IP so I think that shouldn't be an issue.
Any ideas as how I could start troubleshooting this?

wonder if it is some power state setting in your BIOS

Possible but i dont think so, ive been through every nook and cranny of that bios,several times

do other computers work just fine and not just this one?

Cant really say, i dont have any other pcs that support this.
But I think i figured it out, i changed the forwarding for udp 9 on my router to x.x.x.255 so that the magic packet is broadcast over the entire subnet and not just my specific address (i figured that dhcp didnt point anywhere specific after clearing the arp table, but this is just a guess and may be specific to my dlink di 524) Tried it out this morning and worked like a charm, both from wan and lan!
I got some more info from these urls:

Especially article 1.1 from the last link helped a lot. If anything changes ill keep this thread updated, my google searches taught me many people have similar issues.
