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.
