+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,
+
+  1. {phyname} - Use iw dev to get phy name.
+  2. {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`
