8 Ways To Remotely Turn On Computer from LAN and WAN

Wake on LAN over the Internet

We’ll now continue to the more interesting part, booting up a computer from another location through Internet. Let’s say I am in Singapore on a business trip and I need to turn on my computer to retrieve some files. It may seem impossible but it is possible. For Wake-on-LAN over the internet, you must have a router that is turned on in order to wake up a computer over the internet.

Note: Make sure you configure your router to forward port 9 to the computer that you want to boot up otherwise it will not work because the Magic Packet can’t get into your network. Refer to PortForward.com on how to configure port forwarding for your router.

4. Depicus Wake on Lan

At first we found the Depicus Wake on Lan tool that is able to boot up a computer using Wake-on-LAN over the internet.

Something that was very confusing at first about this tool was the Subnet Mask entry. It somehow modifies the entered IP address to become something else. Eventually we came across a simple solution to this issue. Just use the subnet mask 255.255.255.255 and it’ll send the magic packet to the IP address and MAC Address that you’ve specified.


Here are some websites that allow sending magic packets to boot up a computer over the internet. They are free services that can be used by anyone.

You must know the external IP address, MAC address and also the Port. The default port for WOL over the Internet is 9. Some use port 7. Enter the correct information, hit the “Wake Up!” button and it’ll send the magic packet to turn on your computer.

You can also setup a schedule to turn the computer on at a specified time and date.

8. Wake on Lan Monitor

If Wake-on-LAN doesn’t work for you, try using Wake on Lan Monitor/Sniffer. You can use this tool to test if the magic packet is reaching your computer or not.

Tip: There are some routers that supports Dynamic DNS. This is a very useful feature where if your IP address changes, you can still keep track of your current IP address. My Belkin N1 wireless router has this feature and it’s easy to configure. I only need to sign up with DynDNS.org, and enter the information in my Belkin router.

Make Sure Your Computer is WOL Ready

To enable the Wake-on-LAN feature in the BIOS, in addition to an obvious option which is usually named something like “Wake on LAN”, you may have to enable an option called “PCI Devices power on” in the ACPI configuration and power management settings.

You also need to make sure the LAN driver in Windows has the WOL feature enabled. Right click on (My) Computer -> Manage -> Device Manager -> Network adapters. Double click on your Ethernet controller and look in the Advanced tab for a “Wake on LAN” or “Wake from shutdown” option and make sure it’s enabled. Also go into the Power Management tab and tick “Allow the computer to turn off this device to save power”, “Allow this device to wake the computer”, and optionally “Only allow magic packets to wake the computer”.

Also, while the system is switched off, make sure power is still getting to the network adapter by checking to see if the light is on near the connector on the motherboard or card. If not there is no power going to it then other settings may need adjusting. Something else which could stop power getting to the network adapter is a motherboard jumper. Some ASRock boards have a LAN power saving jumper which needs shorting for network adapter power to remain on. Worth checking the manual for this if there is still no network power.
