How to set up a computer to wake up on LAN

In recent years, with the popularity and rapid development of the Internet, computers have become an indispensable part of our lives and work. The use of computers is becoming more and more diversified and convenient, and one of the very practical functions is wake-on-network. Wake-on-LAN refers to remotely waking up a computer through the network, allowing the computer to be operated remotely from a different location or when away from the computer. So, how to set up a computer to wake up on LAN? The following will introduce you to the specific setup steps.

First of all, we need to ensure that the computer’s hardware and network environment meet the requirements for wake-on-LAN. First, make sure that the computer is connected to the LAN or external network to ensure that the network connection is stable. Next, you need to check whether the computer's motherboard has a network card that supports wake-on-LAN function. If not, you need to purchase a network card that supports wake-on-LAN and insert it into the PCI slot of the computer motherboard. In addition, in the computer's BIOS settings, the "Wake up the network card" option needs to be set to on. After these preparations are completed, we can start setting up wake-on-LAN.

Secondly, we need to set up network wake-up in the computer's operating system. For Windows operating systems, we can follow the steps below to set it up. First, open the "Control Panel" and enter "Power Options" in the search bar to open the "Power Options" window. In the Power Options window, click "Change plan settings" on the left, and then click "Change advanced power settings." Next, in the Power Options Settings window, find the "Network Adapter Settings" option and expand it. Set the "Allow only magic packages (or wake pattern packages) to wake the computer" option to "Enabled".

For Mac computers, we can follow the following steps to set it up. First, open "System Preferences" and click on the "Energy Saver" option. Then, in the "Power Saving" window, check the "Enable Remote Wake" option. Then, in "Remote Wakeup Parameters", check the relevant options, such as "Access via Ethernet", "Access via Wi-Fi", etc., and set them according to the actual situation.

It should be noted that in order to ensure the security and stability of wake-on-LAN, we also need to set up the router. We need to enter the router's management interface and find the "Port Mapping" or "Virtual Server" option. Then, map the computer's IP address to the port number required for wake-on-LAN. For specific setting methods, please refer to the router's manual or consult the network operator's technical support personnel.

Finally, in order to achieve the purpose of network wake-up, we also need to use some specific applications or software. For example, on Windows operating systems, we can use Wake-on-LAN software to wake up remotely by entering the computer's MAC address and IP address. On a Mac computer, you can use "Remote Desktop" or other related remote control software to perform network wake-up.

To sum up, setting up a computer to wake up on LAN requires preparation of hardware and network environment, then making corresponding settings in the operating system and router, and finally using a specific application to achieve remote wake-up. Through the wake-on-LAN function, we can remotely operate computers more conveniently, improving work efficiency and quality of life. I hope this article can help everyone understand how to set up wake-on-LAN.
