The 192.168.1.254 IP address should correspond with the IP address you used in the previous step.WOL magic packets are constructed using the MAC address of the target computer, but should be and almost always are sent via broadcast the MAC address used here controls with how the packet is sent, not how it is formed. Do not change the FF:FF:FF:FF:FF:FF MAC address this is a special MAC address used when broadcasting.192.168.1.254 is just an IP address in your LAN's subnet it can be any IP, as long as it is not assigned to any device on your network.Ģ - Add a static ARP entry by typing the following line into the Administration -> Commands section of the Web Interface and then saving with Save Startup.Īrp -i br0 -s 192.168.1.254 FF:FF:FF:FF:FF:FF.Most WOL services will use either UDP port 7 or 9. Here, 9 is the default, but you can use any port number so long as your client wake-up application can talk to a port other than 9.To remotely wake up a computer over the Internet using Wake On LAN- follow these instructions:ġ - Create a port forward rule on the Web Interface ( Applications & Gaming -> Port Range Forward) to the chosen ip: Replace "PP" with the port number your machine listens on (usually 7 or 9). Likewise, replace 192.168.1.255 with the actual broadcast address of the network (192.168.1.255 is the broadcast address when the machine has an IP of 192.168.1.x and subnet mask of 255.255.255.0). Substitute AA:BB:CC:DD:EE:FF with the actual MAC address of the computer which you wish to boot remotely. Note that the full path to "/usr/sbin/wol" is important. If you have local or remote Telnet/SSH access to your router, you can wake up a machine on the LAN by using the following command:

Note: This is the preferred method to send WOL magic packets remotely. If you don't see the WakeOn-type options in your BIOS, usually somewhere in Power Management, your motherboard may not support WOL. Consult your motherboard's manual and BIOS screen (DEL at startup, usually). This feature, if optional, must be enabled in your BIOS otherwise WOL isn't going to work. Wake On LAN is usually disabled by default in most PCs. Once this step is working, you can go on to making WOL work when you are outside your LAN, such as at a cafe or another remote location. Hibernate, Standby, and Power-off the WOL computer, while clicking Send on the second computer, to test each mode to make sure WOL is working. Repeat the previous steps and go over the trouble-shooting tips until they work before proceeding. The WOL computer should respond with a pop-up box showing a packet was received. Use the command 'ipconfig /all' if you don't know what this is.

Get ready to test your set-up by using a utility like WOL Magic Packet Sender (free).Now the computer can normally be started from Hibernate, Standby, or PowerOff modes via a special management packet. Press OK until you are back at Network Connections. Check the second and third boxes to enable WOL. On the LAN adapter of the computer (physical ethernet adapter and/or wireless, given BIOS support), choose Properties/Configure.

You can also use the DD-WRT device's Web Interface to send test packets, in place of a second PC. Ideally, a second PC to test the WOL abilities of the first one.In the example below, we assume your router LAN is 192.168.1.x (the default) and the static IP WOL computer is 192.168.1.254. The WOL computer should have a static IP address, one manually assigned or through static DHCP.Administrative access to the computer you want to sleep/wake-up.The computer is a media server that auto-sleeps, but you want it to wake automatically for file access.You do not want a computer on all the time, yet you want to use it from outside your home or office, and there is a DD-WRT-enabled device as the Internet gateway for that computer, powered on all the time.Most modern computers have the WOL feature - it might be listed under PME (Power Management Events). Wake-On-LAN (WOL) provides the ability to wake a slept/suspended, hibernating, or shut down computer, but the support for this (especially the latter) is dependent upon the hardware and BIOS/UEFI settings. 5.2 Remote Wake On LAN via Port Forwarding.
