There are several ways to wake up a sleeping computer remotely. One common method is to use a Wake-on-LAN (WoL) application, which can be installed on a mobile phone and used to wake up a PC over the internet by inputting the public IP address of the router, the port number, and the MAC address of the PC. Another way is to use a remote desktop application such as Jump Desktop, which can be used to wake up a PC when connected to the same Wi-Fi network. Additionally, tools like on-premise R-HUB remote support servers can also be used to remotely wake up computers from sleep.

What You'll Learn
Using a Wake-on-LAN app
Wake-on-LAN (WoL) is a computer industry standard protocol that allows you to remotely wake up a sleeping computer on your network using another device, such as a phone or laptop. To use this feature, you'll need to ensure that the network card of the computer being woken up supports Wake-on-LAN, which most modern Ethernet adapters do. Wireless adapters, on the other hand, rarely support this feature.
Before using Wake-on-LAN, you must first enable it at the hardware level in the computer's BIOS. To do this, reboot your PC and press a specific key (usually Delete, F2, or another function key) at the boot screen. Once in the BIOS menu, look for the Wake-on-LAN option, which may be found in the sleep and wake settings or under a similar heading.
There are several Wake-on-LAN apps available that you can use to wake up your sleeping computer remotely. TeamViewer is one such popular option that offers built-in Wake-on-LAN support. With TeamViewer, you can easily wake up any sleeping PC connected to your account by simply opening the program and clicking the "Wake Up" button. TeamViewer also provides full control of the target device once it's in wake mode, including the ability to switch it back to sleep mode when you're done.
Another recommended Wake-on-LAN app is NirSoft's WakeMeOnLan, particularly if you're trying to wake a PC from another Windows machine. This app scans your network and provides a list of devices, so you don't need to remember the correct IP address each time. Simply select the machine you want to wake up and hit "Wake Up."
Other remote access tools may also support Wake-on-LAN, so it's worth checking with your preferred program to see if this feature is available and what settings need to be enabled. Additionally, Ubuntu provides a tool to test your computer's compatibility with Wake-on-LAN, which can be installed using the "sudo apt-get install ethtool" command via the terminal.

Configuring the network card
To configure the network card to wake up a sleeping computer remotely, you can follow these steps:
Firstly, ensure that your computer's network card supports the Wake-on-LAN feature. Most modern Ethernet adapters support Wake-on-LAN, but wireless adapters rarely do. Check your computer's documentation or BIOS to confirm if it supports "Wake-on-Wireless-LAN" or "Wake-on-WLAN."
If your computer supports Wake-on-LAN, you can enable this feature in your operating system's Device Manager. On Windows, click the Start menu, search for and open "Device Manager," then find and expand the "Network Adapters" section. Right-click on your Ethernet adapter, select "Properties," and then click on the "Advanced" tab. Here, you should look for a setting called "Wake on Magic Packet" or "Wake on LAN," and ensure it is enabled.
Additionally, you may need to configure your network card's settings to allow the device to wake up the computer from sleep. In the Device Manager, you can find the "Allow this device to wake up the computer" or "Allow wake-up only by magic packet" setting in the Wi-Fi card settings and ensure it is checked.
By enabling these settings, you can use a Wake-on-LAN app on another device, such as a phone or laptop, to send a "magic packet" to wake up your sleeping computer.
It is important to note that Wake-on-LAN is designed to work within your local network. Waking a computer from sleep over the internet can be more challenging and may require additional configurations, such as port forwarding and ensuring the computer has not been sleeping for an extended period.

Using a smart plug
First, ensure that your smart plug is compatible with your computer and network setup. Check your router settings to see if it has a Wake On Lan (WOL) function, which allows you to remotely wake up devices connected to your network. This feature is available on many routers, including older models.
Next, configure your computer's power settings. Set your computer to power down while leaving the power connected to the smart plug. This ensures that you can remotely power it up when needed. You can do this by sending a "magic packet" to the NIC's MAC address, which is a unique identifier for your computer's network interface card.
Now, set up your smart plug. Connect your computer to the smart plug, and ensure that the smart plug is turned on. You can then use a Wake-on-Lan app or a similar tool to send the magic packet to your computer's MAC address, which will power it up remotely.
Additionally, you can enhance security and convenience by integrating a smart hub or home automation system. This allows you to control the smart plug and set up automated routines or schedules for your computer's power management.
By following these steps, you can effectively use a smart plug to wake up your sleeping computer remotely. This method provides remote access, ensures seamless operations, and can contribute to energy savings and sustainability goals. Remember to follow the manufacturer's instructions for your specific smart plug model and to ensure that your network and computer settings are properly configured for remote wake-up functionality.

Using a remote support server
To wake up a sleeping computer remotely, you can use a remote support server. This method involves using a Wake-on-LAN (WoL) program and setting up port forwarding on your router.
First, you need to install a WoL app on your device. There are various WoL apps available, such as the WakeOnLan program mentioned in one source. You can install a WoL app on your phone and use it to wake up your PC.
Next, you need to configure your router. In the router settings, you should redirect a port to port 9 on your PC. The specific port number you redirect may vary, but the default port for WoL apps is port 9. You will also need to know the public IP address and MAC address of your PC.
Once you have the necessary information, you can use the WoL app to wake up your PC remotely. Launch the WoL app and enter the public IP address of your router, the port number you redirected, and the MAC address of your PC.
Additionally, you may need to adjust the subnet mask in the WoL app settings. In some cases, the default subnet mask may not work, and you may need to change it to 255.255.255.255.
It's important to note that this method may not work if your PC has been sleeping for an extended period, such as 48 hours. In such cases, waking the PC may only be possible from the local area network (LAN) rather than over the internet.

Using a separate WakeOnLan program
To wake up a sleeping computer remotely, you can use a separate Wake-on-LAN (WoL) program. WoL is an industry-standard protocol that allows you to power up a computer from anywhere, as long as it is connected to your local network.
To use WoL, the target computer must meet certain configuration requirements. First, the network card of the computer must support WoL. Second, you need to enable WoL at the hardware level in the computer's BIOS. To do this, reboot your PC and press a specific key (usually Delete, F2, or another function key) at the boot screen to access the BIOS menu. Once in the BIOS menu, look for the Wake-on-LAN option, which may be labelled as "PCI Power Up", "Allow PCI Wake Up Event", or "Boot from PCI/PCI-E".
Additionally, you need to enable WoL on the operating system (OS) side. On Windows, click the Start menu, open Device Manager, and find the Network Adapters section. Right-click on your Ethernet adapter, select Properties, then click on the Advanced tab. Scroll down to "Wake on Magic Packet" and ensure it is enabled.
Once WoL is enabled on the target computer, you can use a separate WoL program to wake it up remotely. There are various WoL programs available, such as NirSoft's WakeMeOnLan for Windows, Mocha WOL for iOS, or Wake On Lan for Android. These programs allow you to scan for devices on your network and send a "magic packet" to wake up the target computer.
It's important to note that WoL is designed to wake up computers on your local network, so you won't be able to use it to wake up a computer on a different network, such as a computer at home while you're at a coffee shop. Additionally, the target computer must be in a low-power sleep mode, as WoL is not supported from a full shutdown state in Windows.
