  • This one offers to wake up a machine just by ping ??? I don't understand how that would work, and it doesn't sound safe to me.

Actually the other answer is quite old and not up to date.

Please use the iw tool.

To check whether it's supported: iw phy0 info

Check the status: iw phy0 wowlan show.

Activate several options: sudo iw phy0 wowlan enable magic-packet disconnect.

The kernel wiki has some information as well. If wake on wlan does not work from suspend mode try freeze mode: Close all applications, then sync && echo freeze | sudo tee /sys/power/state. This is not as low power, but less than a running system and nice to test whether the magic packets at get there and the driver interprets them.

Also, check if Your wireless card support WakeOnLan, and You must have kernel version >= 3.1

  • There is a boot option, and there is a drop down box with 3 options, disabled, network boot or boot order. I have it set to network boot. ethool eth0 shows pg as wol. Why would the kernel version matter if the OS is not even loaded ??

  • I'm almost sure that it won't be in boot options. And as of why kernel >= 3.1 phoronix.com/scan.php?page=news_item&px=OTgwMg

  • Moreover this site seems to say that magic pacckets for wireless lans don't exist, this one seems to say differently: revolutionwifi.blogspot.fr/2010/11/wake-on-wireless-lan.html From what I understood, the link you mentionned offers to wake up by ping. How would that work, and isn't it a security concern ?
