I'm trying to set up WOL for my desktop. I've enabled the feature in BIOS and set my router config to send magic packets on the wired connection, but clearly there's something else I need to do. Wakeup does work from the front panel button on the case, but nothing happens when I try it over the LAN.
WOL is often problematic, you should at least try to see
- if your client is really sending the packet (sniff the network and
check); if not, try to specify interface or similar options
- if the machine has an active ethernet interface (if the LEDs on it
or on the switch are off, no chance, there must be at least 10/100Mbit/s link active); if not, you have to enable WOL (or wake on event) in the BIOS, or with ethtool on a booted system
Bad experience I had in the past (or present):
- NIC firmware bugs requiring you to send the MAC with octects in
reverted order
- WOL listening only after a shutdown; if the power goes away and
comes back WOL doesn't work anymore (the BIOS was just "playing dead" waiting, but needing power to keep this state)
Thanks.
