translating by lujun9972 How to configure wireless wake-on-lan for Linux WiFi card

[![linux-configire-wake-on-wireless-lan-wowlan][1]][1] Wake on Wireless (WoWLAN or WoW) is a feature to allow the Linux system to go into a low-power state while the wireless NIC remains active and stay connected to an AP. This quick tutorial shows how to enable WoWLAN or WoW (wireless wake-on-lan) mode with a wifi card installed in a Linux based laptop or desktop computer.

Please note that not all WiFi cards or Linux drivers support the WoWLAN feature.

Syntax

You need to use the iw command to see or manipulate wireless devices and their configuration on a Linux based system. The syntax is:

iw command
iw [options] command

List all wireless devices and their capabilities

Type the following command:

$ iw list
$ iw list | more
$ iw dev`

Sample outputs:

phy#0
	Interface wlp3s0
		ifindex 3
		wdev 0x1
		addr 6c:88:14:ff:36:d0
		type managed
		channel 149 (5745 MHz), width: 40 MHz, center1: 5755 MHz
		txpower 15.00 dBm

Please note down phy0.

Find out the current status of your wowlan

Open the terminal app and type the following command to tind out wowlan status: $ iw phy0 wowlan show Sample outputs: WoWLAN is disabled

How to enable wowlan

The syntax is: sudo iw phy {phyname} wowlan enable {option} Where,

{phyname} - Use iw dev to get phy name.
{option} - Can be any, disconnect, magic-packet and so on.

For example, I am going to enable wowlan for phy0: $ sudo iw phy0 wowlan enable any OR $ sudo iw phy0 wowlan enable magic-packet disconnect Verify it: $ iw phy0 wowlan show Sample outputs:

WoWLAN is enabled:
 * wake up on disconnect
 * wake up on magic packet

Test it

Put your laptop in suspend or sleep mode and send ping request or magic packet from your nas server: $ sudo sh -c 'echo mem > /sys/power/state' Send ping request from your nas server using the [ping command][3] $ ping your-laptop-ip OR [send magic packet using wakeonlan command][4] : $ wakeonlan laptop-mac-address-here $ etherwake MAC-Address-Here

How do I disable WoWLAN?

The syntax is: $ sudo phy {phyname} wowlan disable $ sudo phy0 wowlan disable

For more info read the iw command man page: $ man iw $ iw --help
