How to enable Wake on Lan (WOL) with Advanced TomatoUSB wifi router firmware

I recently installed TomatoUSB advanced firmware on my Asus RT-AC66U wifi router. This router act as my wireless Ethernet bridge. TomatoUSB advanced has additional features like

SSH
Multiple WAN support (3G/4G/Static IP/Cable/ADSL2)
Tor
Virtual Wireless
DMZ
IPv6
FTP/Media server via USB
BiTorrent Client via USB
UPS support
OpenVPN client and server
Tinc VPN server and much more.

I also connected my 2 bay NAS to this server. Sometimes I need to wake up my NAS using WOL.

What is WOL?

Wake-on-LAN (WOL) is an Ethernet networking standard that allows a server to be turned on by a network message. You need to send ‘magic packets’ to wake-on-LAN enabled ethernet adapters and motherboards, to switch on the called systems.

Option #1 Use ssh and ether-wake command on your wifi router

I log in to my TomatoUSB powered router using the following command:
$ ssh [email protected] $ ssh [email protected] $ ssh [email protected]
Sample output:

ether-wake command syntax

The ether-wake command send a magic packet to wake up sleeping nas server. Of course MAC must be a station address (00:11:22:33:44:55) or a hostname with a known ‘ethers’ entry. I prefer MAC address:
ether-wake MAC ## Send a magic packet to this MAC ether-wake -b MAC ## Broadcast the packet ether-wake -i eth0 MAC ## Interface to use (default eth0) ether-wake -i eth0 -p PASSWORD MAC ## Append 4/6 byte PASSWORD to the packet
For example:
# ether-wake 00:11:32:11:15:FC

Option #2 Use Advanced TomatoUSB web interface

This is much easier option. Fire the web-browser and type your wifi routers URL:
https://192.168.2.252
Click on Tools > WOL tab > Type 00:11:32:11:15:FC in MAC Address List box > Wake up button:

That is all. Now I do not have to go to another room to wake up my little NAS server.

Also, see my previous posts on the same topic

You can also use etherwake on Linux or Unix-like system:

Next time I intend to write about how to install (flash) Advanced TomatoUSB wifi router from Linux, FreeBSD or MacOS desktop.
