Waking up a sleeping computer remotely requires sending a wake-up packet directly to the device, which is not possible if the computer is behind a router or in some cases, two routers. This is where Wake-on-Local Area Network (WoL or Wake on LAN) comes in. WoL enables the remote wake-up of sleeping computers using a Magic Packet. Proper setup in BIOS, Windows settings, and network configurations is required. Wake-on-Wide Area Network (Wake-on-WAN) allows wake-up over the internet but requires port forwarding or a VPN. There are alternative methods to WoL and Wake-on-WAN, such as TSplus Remote Support, smart power switches, and Jump Desktop.

What You'll Learn
Waking a computer outside your home network
Waking a computer from outside your home network is possible, but it requires some technical knowledge and specific hardware and software. Here are some methods to achieve this:
Wake-on-LAN (WoL)
Wake-on-LAN is a feature that allows you to wake up a computer on your network. However, it can also be used from outside the network with some additional steps. First, you need to enable WoL in your computer's BIOS. This may involve rebooting your PC and pressing a specific key (such as Delete or F2) to access the BIOS menu and enabling the WoL option.
To use WoL from outside your network, you need to forward the WoL packets from your external IP address to the internal host IP address. This can be done by creating a static arp entry in your router for the host you want to wake up and then setting up port forwarding. The port is usually 7 or 9, and the broadcast address is typically the router's IP address with ".255" as the last octet (e.g., 192.168.1.255).
Always-on Device and Magic Packets
Another method is to have an always-on device inside your network, such as a home server or an old laptop, that you can remote into. From this device, you can send "magic packets" to your sleeping workstation to wake it up. This can be done using software like Chrome Remote Desktop or SSH. Once your workstation is awake, you can remote into it.
TeamViewer
TeamViewer is a popular software that allows you to wake your PC from sleep and take control of your desktop remotely. It requires setting up a TeamViewer account and configuring your computer. You can then use your phone or another device with the TeamViewer app to wake your PC.
Alexa's WOL Skill
If you have the Alexa app on your phone and an Echo device on your home network, you can use the WOLSkill to wake your PC by asking Alexa to turn on your computer.
These methods provide ways to wake a computer from outside your home network, but it is important to note that they may vary in complexity and ease of use.

Using TeamViewer to control your desktop
TeamViewer is a software that allows users to remotely access and control computers and other devices. It is commonly used to provide remote technical support, access files and applications from a distance, and manage computers and devices that are not physically accessible. With TeamViewer, you can establish a connection between two devices over the internet, enabling remote control of the target device from the host device.
To use TeamViewer to control your desktop remotely, follow these steps:
- Install TeamViewer on both the host device (the device you will be using to control) and the target device (the device you want to control). TeamViewer is available for Windows, macOS, Linux, and mobile operating systems.
- Launch TeamViewer on both devices.
- On the host device, locate and click on the "Settings" icon, usually found in the left panel.
- In the "Settings" menu, look for the "General" option and click on "Account Assignment."
- Enter your TeamViewer account credentials and click "Assign."
- Now, you will enable the Wake-on-LAN feature. Click on "Configure" next to "Wake-on-LAN."
- Add the TeamViewer ID of the target device. This is necessary to establish a connection between the two devices. Click "Add" and then "OK" to confirm.
- On the target device, ensure that it is connected to a power source, has an internet connection, and is in sleep mode or hibernation mode.
- On the host device, navigate to the "Devices" section and select the target device from your device list.
- Click on "One-click control" or a similar option to wake up the sleeping target device.
- Enter your computer password, if prompted, to enable unattended remote access.
- You should now have remote control of your desktop through the host device.
Note that for Macs, you can only wake them up from sleep mode, not when they are fully powered down, due to Apple's restrictions. Windows and Linux PCs can be woken up from sleep, hibernation, or even fully powered down states, as long as the hardware supports it. Additionally, make sure that TeamViewer is added to the AutoStartup list on the target device to ensure it works as intended.

Preventing your computer from sleeping
While it is possible to wake up a sleeping computer remotely, there are also several ways to prevent your computer from sleeping in the first place.
If you are using a Windows operating system, you can prevent your computer from sleeping by opening Windows Media Player and clicking play on a picture, which will play the picture as a slideshow. Alternatively, you can open a draft email or a notepad app and place something on your space bar to keep it "spacing" while you are away. Another method is to use a Powershell script that calls win32.userinput and a short loop to monitor the idle time and last user input time, resetting the idle count whenever there is user activity.
If you are using a Mac, you can prevent your computer from sleeping by adjusting your power settings. Go to System Preferences > Energy Saver and adjust the settings so that your computer never sleeps when idle.
Additionally, there are several third-party applications that can prevent your computer from sleeping. For example, the "Move Mouse" app for Windows can be set to shake the cursor at regular intervals, preventing the PC from sleeping. Similarly, the Caffeine app for Mac can be used to temporarily prevent your computer from sleeping, and you can even set an activation period so that your computer stays awake during specific times.
By following these methods, you can prevent your computer from sleeping and maintain uninterrupted access to your device.

Using Wake-on-LAN to wake your PC
Wake-on-LAN (WoL) is a useful feature that allows you to turn on your PC from sleep mode without physically pressing the power button. This can be done from another room in your house or even remotely from outside your local network. Here is a step-by-step guide on how to use Wake-on-LAN to wake your PC:
- Enable Wake-on-LAN in BIOS: To do this, reboot your PC and press a specific key (usually Delete, F2, or another function key) at the boot screen to enter the BIOS menu. Locate the Wake-on-LAN option, which may be under sleep and wake settings or a similar category. Toggle the setting to "Enabled".
- Check Network Card Compatibility: Ensure that the network card of the computer you intend to wake up supports Wake-on-LAN. Not all network cards are compatible with this feature.
- Use a Remote Access Tool: There are various remote access tools available that support Wake-on-LAN, such as TeamViewer, NirSoft's WakeMeOnLan, Depicus, Mocha WOL (iOS), or Wake On Lan (Android). Open your chosen program and look for the "Wake Up" button or a similar option.
- Send a "Magic Packet": With Wake-on-LAN, you can send a "magic packet" from your phone, laptop, or another device on the same network. This packet is a specially constructed Ethernet packet that wakes up the sleeping computer.
- SSH into a NAS Device or Raspberry Pi: If you have a NAS device or Raspberry Pi, you can SSH into it and use the command line to send the "magic packet". As long as the packet originates from within the network, Wake-on-LAN should work smoothly.
- Consider Power Settings: On Windows 10, the default shutdown behaviour puts the system into a hybrid shutdown or Fast Startup (S4) state, where Wake-on-LAN is unsupported. Ensure that your power settings allow the computer to sleep (S3) or explicitly enter the hibernate (S4) state to successfully use Wake-on-LAN.
By following these steps, you should be able to effectively use Wake-on-LAN to wake your PC from sleep mode remotely or from another location within your house.
