WOL is not working after a software power off
When in my Fedora 10 I power off the system, by using the gnome icon or even the command line "poweroff", it shut down the machine and power off it as expected - EVEN THE NIC. I can see its led is off !
This happens when I put the machine in hibernate mode too, but not in suspend mode.
When I power on and and power off it just after the POST messages, when grub is waiting a key to select an option, I can see the NIC's led is still blinking at each second or so.
When I power on the machine and select windows (dual boot system) and then power it off, it power off as expected, I mean, it leaves the NIC on - the led blinks even with the machine powered off.
As result, I can't wake up my machine remotely by using Wakeup-On-Lan since the NIC is powered off by Fedora.
There is a way to control this, or a work around ?
Do you think I must post a bug report on kernel list ?
check the search details against your kernel version (uname -r)
Thank you grepmasterd !
Yes, it is not a kernel bug, but a "feature" of network driver.
Looks like the network driver does not check the BIOS information about WOL and always initialize the NIC with WOL disabled.
Not a big problem at all. A simple "ethtool eth0 -s wol g" at boot time enable wol again.
In fact, in Fedora 10, just putting ETHTOOL_OPTS="wol g" on /etc/sysconfig/network-scripts/ifcfg-eth0 would do the trick.
hello i have applied these changes and WOL is working fine when i used it to wake my machine from turn off mode....
But it is not working when i switches my machine to sleep mode. My machine is not responding to magic packet sent , if it is in sleep mode. Also this all happens with ubuntu only .....If i go to sleep mode through Windows 7 ultimate. Then my machine can detect the magic packet and resume all the state of machine as earlier.
Can WOL for sleep/suspend/hibernate is possible in ubuntu......if yes do we require some more changes and what are those changes required.
When I turn off Ubuntu WOL works, (the led on the ethernet is on)
but when I put it to sleep mode, WOL just doesn't work (the led on the ethernet jack is off)
