I've got a Dell Optilex 3080 MFF set up as a proxmox server for my home lab. I got the WOL setting set and tested it.
To my surprise, I can't bring it up back after getting back up in the morning. What I noticed was that the ether3 link light was off from my hex gr3. I'm pretty sure no one plugged it off so was wondering what caused the light to turn off rendering WOL inoperable.
When I unplugged and plugged back in the Optiplex, the link light came back, which made WOL work again.
Does this router have some sort of setting that could have turned the link off after a while? I can't really tell how long cause I was asleep overnight :p
