TeamViewer's Wake-on-LAN tool can wake a sleeping computer
TeamViewer's Wake-on-LAN (WoL) tool allows users to power up computers remotely. This means that, if your computer is sleeping or powered off, you can use Wake-on-LAN to turn it on and establish a connection. Wake-on-LAN is a computer industry standard protocol for remotely reactivating a computer from a low-power or powered-down mode.
To use Wake-on-LAN, the remote computer must have its WoL settings enabled. This means that, even when the device is powered down, there is sufficient power for the device's network interface card (NIC) to remain receptive to communications in standby mode. The WoL software then broadcasts a small data signal, known as a "magic packet", to the NIC of the target device. This packet is designed to be processed quickly and easily by the NIC, using very little power. When the WoL-enabled NIC receives the magic packet, it checks it for the correct information.
TeamViewer Remote comes with built-in Wake-on-LAN support, which means you can maintain machines for long periods, even if they are turned off or in low-power or hibernate mode. When you need to, you can use TeamViewer's WoL function to reactivate and control your devices from anywhere with minimal disruptions to business operations. For example, you can use Wake-on-LAN for maintenance, support, monitoring, or to access work applications and files from home.
To wake up a device remotely using TeamViewer, go to Settings, then to Network under the Device menu, and click Wake-on-LAN. If you want to wake up the remote computer via its public address, you will need to configure Wake-on-LAN accordingly. In the address field, enter the fixed IP address or DNS name of the computer, and in the port field, enter the UDP port via which the computer can be reached.

The computer must support Wake-on-LAN
Wake-on-LAN (WoL) is an Ethernet or Token Ring computer networking standard that allows a computer to be turned on or awakened from sleep mode by a network message. The message is usually sent to the target computer by a program executed on a device connected to the same local area network (LAN). It is also possible to initiate the message from another network by using subnet-directed broadcasts or a WoL gateway service.
To enable Wake-on-LAN on your computer, it should be connected to an ATX-compatible power supply with an extra +3.3V voltage rail. A voltage rail gives a device the ability to switch between alternating current and direct current power. The computer must also have a network interface card (NIC) that is Wake-on-LAN-enabled. The NIC listens for incoming "magic packets" even when the rest of the system is powered down. If a magic packet arrives with the device's MAC address, the NIC signals the computer's power supply or motherboard to awaken.
Wake-on-LAN can be implemented in various ways, including subnet-directed broadcasts, unicast network packets, and wireless WoL. However, it is important to note that wireless WoL is not recommended as it will keep the Wi-Fi adapter always on, leading to battery drain and possible overheating. Additionally, most 802.11 wireless interfaces do not maintain a link in low-power states and cannot receive a magic packet.
Wake-on-LAN offers several benefits, including remote management of devices, improved efficiency, and reduced costs for organizations. It eliminates the need for IT administrators to physically access devices, saving time and money. However, it is essential to consider the security implications of direct broadcasts and ensure proper configurations to maintain data security.
Overall, Wake-on-LAN provides a valuable tool for managing large numbers of devices within an organization, enhancing operational efficiency, and streamlining power management.

The computer must be connected to the internet via an Ethernet cable
TeamViewer is a useful tool that allows users to access files on their computer and even wake up a sleeping computer remotely. This can be achieved using the Wake-on-LAN (WoL) feature, which involves sending a "magic packet" over the network to the target device. However, for this remote wake-up feature to work, the computer must be connected to the internet via an Ethernet cable.
An Ethernet connection is a key requirement for successfully using TeamViewer's Wake-on-LAN functionality. While modern computers often support Wake-on-LAN, the tool's effectiveness can be limited if the computer is in hibernation mode or completely powered off. In such cases, an Ethernet connection becomes crucial for ensuring a reliable connection to wake up the sleeping computer.
The Ethernet cable connection is specifically required for the Wake-on-LAN feature to work. TeamViewer's ability to access files and interact with a sleeping computer relies on this direct and stable network connection. This is in contrast to a Wi-Fi connection, which may not provide the same level of support for Wake-on-LAN functionality.
To ensure the best chance of success when using TeamViewer to wake up a sleeping computer, it is advisable to follow certain steps. First, enable Wake-on-LAN in the computer's BIOS settings. When the computer starts up, access the BIOS setup by pressing the prompted key, navigate to the Power tab, enable Wake-on-LAN, and then save and exit. With this setting configured, you can now utilize TeamViewer's remote wake-up feature effectively.
By connecting the computer to the internet via an Ethernet cable and following the necessary steps to enable Wake-on-LAN, users can take advantage of TeamViewer's capabilities to access their files and wake up their computers remotely, even when the computer is in sleep mode. This combination of an Ethernet connection and the Wake-on-LAN feature enhances the functionality and accessibility of TeamViewer, making it a valuable tool for remote computer management.

Wake-on-LAN is a technology that uses a magic packet to wake a sleeping computer
Wake-on-LAN (WoL) is a computer networking standard that allows a computer to be turned on or awakened from sleep mode by a network message. This network message is known as a 'magic packet'.
The magic packet is a special type of broadcast Ethernet frame that can be transmitted over Wi-Fi or hardwire. It is sent to the media access control (MAC) address of the destination computer, which is a unique identifier built into each network interface controller (NIC). The NIC listens for incoming packets even when the rest of the system is powered down, and if it receives a magic packet addressed to its MAC address, it signals the computer's power supply or motherboard to awaken, just as if the power button had been pressed.
The magic packet was developed by AMD in cooperation with Hewlett-Packard and was proposed as a standard in 1995. It was quickly adopted by IBM, Intel, and others. Wake-on-LAN can be used to wake a computer within a subnet or, with the appropriate configuration and hardware, across any network, including remote wake-up across the internet.
It's important to note that Wake-on-LAN has some limitations. It can only wake a sleeping computer and cannot cold start a PC that is not already in sleep mode. Additionally, wireless WoL is technically possible but not recommended due to battery drain and potential overheating issues. Furthermore, most 802.11 wireless interfaces do not maintain a link in low-power states and cannot receive a magic packet.
