Waking up a Windows 7 PC from sleep remotely is possible through a feature called Wake-on-LAN. This feature allows users to turn on their computers using a network connection, eliminating the need to physically press the power button. To enable Wake-on-LAN, users may need to adjust power options in the BIOS or Windows Control Panel, and ensure their network card supports the feature. Additionally, the computer needs to be configured to receive a magic packet on Port 9, which can be sent from another device using a Wake-on-LAN app or program. With these steps, users can conveniently wake up their Windows 7 PCs from sleep mode without being physically present.

What You'll Learn
Using a Wake-on-LAN app
There are several Wake-on-LAN (WoL) apps available that can help you wake up a Windows 7 PC from sleep remotely. Here is a guide on how to use one:
First, you need to install a Wake-on-LAN app on your device. One option is AquilaWOL, a free, open-source network management software developed by Aquila Technology LLC. It provides remote wake on LAN or shutdown commands for users managing a network of computers. Another option is WakeMeOnLan, which is also a free utility that can wake up computers on your network with Wake-on-LAN packets. It offers an intuitive user interface and supports multiple languages.
Once you have installed your chosen WoL app, you need to configure your router to always forward Magic Packets (on Port 9) to your Windows 7 PC. This can be done by accessing your router's settings and redirecting a port to Port 9 on your PC. Make sure that your PC always has the same IP address, as some routers dynamically assign IP addresses, which may cause issues with remote wake-up.
In the WoL app, you will need to specify the unique MAC address of the network card or wireless adapter of the PC you want to wake up. This can often be found in your router's settings. Additionally, you may need to set the subnet mask to 255.255.255.255 if you are using the WoL app from the internet, as the default setting of 255.255.255.0 is for LAN-only configurations.
Now, whenever you want to wake up your Windows 7 PC from sleep remotely, simply open your WoL app and send a wake-up packet to the MAC address of your PC. Your PC should then power on and resume from sleep mode.
It is important to note that some WoL apps may only work on local networks, so if you are trying to wake up your PC from outside your local network, you may need to use a different solution or configure your network settings further.

Sending a magic packet
To wake up a Windows 7 computer from sleep mode remotely, you can use the Wake on LAN (WoL) feature. This works by sending a "magic packet" over the network.
To enable WoL, you need to ensure your hardware and network adapter support it. You can then enable WoL through your motherboard settings or an add-in network card's firmware.
Once WoL is enabled, you can send a magic packet to wake up your Windows 7 computer remotely. Here are the steps to follow:
- Configure your router to always forward Magic Packets to your computer. This is typically done by setting up port forwarding on Port 9.
- Ensure your computer always has the same IP address.
- Obtain the MAC address of your computer.
- Use a third-party app or script to send the magic packet.
Some popular choices for sending magic packets include TeamViewer, which is free for non-commercial use, and WakeOnLan, which can be used with a VPN for remote access.
It is important to note that some troubleshooting may be required if your computer does not wake up as expected. For example, if your hardware does not support WoL, you may need to use a USB network adapter, and ensure that fast startup is disabled.

Configuring the router
To configure your router, you will need to access its settings. This can usually be done through a web interface by entering the router's IP address into a web browser. Log in with the appropriate credentials to access the router's configuration page.
Once you are in the router's settings, locate the port forwarding or port-forwarding rules section. This may be found under a different name depending on your router model, but it is typically within the "Advanced" or "Firewall" settings.
In the port forwarding section, you will need to create a new rule to forward port 9 (or port 7, in some cases) to the static IP address of the computer you wish to wake up. This ensures that the router always sends the wake-up request, often called the "Magic Packet," to the correct device.
The specific steps to create this rule may vary depending on your router model, but you will typically need to enter the following information:
- Port Number: Forward port 9 (or port 7) to your computer's IP address.
- IP Address: Enter the static IP address of the computer you wish to wake up. This should be the same address you set up for your computer.
- Protocol: You can use either UDP or TCP, or select both to ensure compatibility.
By configuring the router in this way, you are instructing it to always forward any incoming Magic Packets to your computer, allowing it to wake up from sleep mode remotely.
Additionally, if your router has more advanced configurations, such as running DD-WRT firmware, you can explore alternative methods. One such method involves using a combination of port forwarding and ARP tables to trick the router into forwarding the port to the broadcast address. This approach is known as Wake-on-WAN and is described in more detail on the DD-WRT wiki.
Remember, the exact steps for configuring your router may vary slightly depending on the make and model, so it is always a good idea to refer to your router's manual or manufacturer's website for specific instructions.

Using a remote desktop program
To wake up a Windows 7 computer from sleep remotely, you can use a remote desktop program in conjunction with the Wake-on-LAN (WoL) feature. Here's a step-by-step guide:
- Enable Wake-on-LAN: First, you need to enable Wake-on-LAN on your Windows 7 computer. This can be done by accessing the BIOS settings. When rebooting your PC, press the appropriate key (usually Delete, F2, or another function key) to enter the BIOS menu. Look for the Wake-on-LAN option, which may be found in the sleep and wake settings or under a similar name, such as "Resume By PCI-E Device." Ensure that this feature is enabled.
- Configure Router: Next, you need to configure your router to forward "magic packets" to your computer. These magic packets are what will wake up your computer from sleep. Set up port forwarding on your router to forward incoming packets on port 9 to your computer's MAC address.
- Use a Remote Desktop Program: Install a remote desktop program, such as Chrome Remote Desktop or TeamViewer, on a separate device, such as your phone or another computer. Ensure that this device is on the same network as your Windows 7 computer.
- Send a Magic Packet: Using your remote desktop program, send a magic packet to your Windows 7 computer's MAC address. This will wake it up from sleep. You may also need the IP address of your router or the dynamic domain address you created during the router configuration step.
- Establish Remote Connection: Once your Windows 7 computer is awake, you can now establish a remote connection to it using your remote desktop program. Access your files, run programs, and utilize your Windows 7 computer as if you were sitting in front of it!
Remember that Wake-on-LAN typically works only on computers within the same local network. If you are trying to wake up your Windows 7 computer from a different network (e.g., when you're away from home), you may need to set up port forwarding on your router for port 3389, which is the standard port for RDP (Remote Desktop Protocol) connections. However, this may expose your computer to security risks, so proceed with caution and ensure you have strong passwords and up-to-date security patches.
