Online Wake-on-LAN Services
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.
6. Wake-On-LAN Online
This webpage is able to send the required packet data to your computer over the internet. A useful feature is the scheduler that allows you to send the magic packet on a specific day and time up to a week in advance.
Enter the external IP address and MAC address of the target computer into the boxes. Then press “Wake Up my PC!” The service seems to use both ports 9 and 7 by default but you can add your own with “:[port]” after the IP address. Multiple MAC and IP addresses can be used if you separate them with commas.
7. Depicus Wake on LAN over the Internet
In addition to the Windows tools from Depicus, they also have a page on their website that can send the magic packet over the internet to your computer.
The external IP Address and MAC Address of your computer is required. The subnet mask and password boxes can be left alone if you have no specific need to change them. The page also says the port can be left at the default of 4343 but we got an error if the box was empty. Port 9, 7, 4343 or anything more specific if you wish is fine.
Wake-on-LAN from the Command Line or PowerShell
Using the command line or PowerShell to send Wake-on-LAN packets to another computer can be quite useful for business, professional users, in batch scripts and to make desktop shortcuts.
8. Wake On Lan Command Line (WolCmd)
This tool is another entry in our list by Depicus and is a simple command line tool to send the Wake-on-LAN signal. The syntax is quite simple.
WolCmd [MAC address] [IP address] [Subnet mask] [Port]
An example would look like this:
wolcmd 26-63-A4-79-B8-12 192.168.0.40 255.255.255.0 9
The MAC address, IP address and subnet are required but the port will default to 7 if you don’t supply one.
Another useful command line tool we found was simply called WOL. It additionally allows you to supply a password and a custom subnet.
9. Send-WOL PowerShell Script
There are a few PowerShell scripts around that can send a magic packet and this one is hosted on the Microsoft Technet Script Center. Download the script, open it and add the argument for the computer(s) you wish to wake.
Send-WOL -mac [MAC address] -ip [IP address] -port [port]
Save the script and execute it from PowerShell or the command line. Only the MAC address is truly required, the default port will be 9 if you don’t supply your own.
Use Wake-on-LAN to Start a Computer From your Smartphone
If you are unable to send the magic packet to your PC from another computer, an alternative option is sending it from another device like a smartphone or tablet. There are loads of apps around and the Android app we’ll look at is free, popular and does the job quite nicely.
10. Wake On Lan for Android
This app is quite easy to use because if the computer to start up remotely is switched on and available on the local network, you can find it automatically. Just press the add button and select the device from the list. It’s IP and MAC addresses will be added so you don’t have to do anything else. If you are connecting from outside the LAN, replace the local IP with the external IP or add a new connection manually.
All you have to do is press one of the devices in the bookmarks list to start the computer remotely. A handy function is the ability to add a widget to your home screen that can send the packet data to a selected device just by pressing the icon. By default the magic packet is sent three times, it can be changed up or down in the app settings.
Test Wake-on-LAN is Working in Windows
If Wake-on-LAN isn’t working or you just want to test to see if the remote computer is receiving the necessary data, try using Wake on Lan Monitor. It’s another tool from Depicus and can be used to test if the magic packet is reaching the target computer.
Launch the tool on the computer you want to send the WOL signal to, set the required port and press Start. Then send a Wake-on-LAN packet from another computer using one of the options above. If the data is received, the tool will display it in the window. If you receive nothing there is something in your set up preventing the packet from being sent.
Note that different programs default to different ports when sending the magic packet. For instance, FUSION WakeUp on Lan and WakeMeOnLan default to port 40000 while WakeOnLANx defaults to port 7. If you are not required to set a port in the program, make sure you know what its default is during testing.
Make Sure Your Computer is Wake-on-LAN 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 “Wake on LAN”, “Wake from shutdown”, “Wake on Magic Packet” or similar.
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”.
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.
