Teamviewer wake on lan tutorial11/20/2023 Good to know: Although Wake-on-LAN offers a high degree of flexibility and convenience, starting the computer remotely is not always desirable. Additional software, on the other hand, is not necessary. The basis for this is the BIOS or a specific firmware for the network card. However, the Ethernet or wireless card must also support the functionality. This component has already been installed in most end devices for over 10 years. An ATX-compatible power supply ensures that the function works. Whether it is possible to use Wake-on-LAN depends on the motherboard and the network card. For private use, on the other hand, data can be transferred to mobile devices while the PC remains at home. This makes file transfer within the company much easier. Programs such as TeamViewer or VNC are just as accessible as game server or file server programs. After all, the computer is in energy-saving mode during this time. At the same time, companies benefit from a high degree of cost-effectiveness. Since this standard enables remote access, everyday tasks can be performed without further ado: Accessing data and programs as well as running applications works smoothly. What makes it special is that the WoL does not require a LAN connection. It is an industry standard protocol from the 1990s. If the letter 'g' is listed here, it means that the functionality is available.Wake-on-LAN (WoL) is a way to remotely reactivate a computer from a low-power mode. The result is a listing in which the section 'supports Wake-on' can be found. The command 'sudo ethtool eth0' provides information about this. Afterwards, it is possible to check the Wake-on-LAN compatibility via the Powershell. The software tool is installed using the 'sudo apt-get install ethtool' command via the terminal. At the same time, Ubuntu provides a tool that can be used to test the computer’s compatibility. Under Linux, for example under Ubuntu, it is also possible to provide Wake-on-LAN. The value g is required for WoL to work, if not, the following command enables the WoL feature in the driver: The Wake-on values define what activity triggers wake up: d (disabled), p (PHY activity), u (unicast activity), m (multicast activity), b (broadcast activity), a (ARP activity), and g (magic packet activity). To query whether WoL is enabled on the network adapter, install ethtool, determine the name of the network interface and query it using the command: Look for terminology such as 'PCI Power up', 'Allow PCI wake up event' or 'Boot from PCI/PCI-E'. To enable the WoL feature in the BIOS, different motherboard manufacturers use slightly different language. In this way, you get full wake-up, remote access and control capabilities all in one easy-to-use solution. for this method, the other ‘intermediary’ computer must be turned on and TeamViewer must be installed and configured on it).įor both WoL via a public address and WoL via the network, once your target device is in wake mode, TeamViewer Remote gives you full control of it – including the ability to switch it back into ‘off’ or ‘sleep’ mode when any task at hand is complete. non-internet-enabled point-of-sale equipment, industrial devices, or any other devices that you do not want to be connected directly to the internet – you can wake it up by sending a message via another computer on its network. This is useful for PCs and other pieces of equipment that are clearly identifiable on the internet at all times.Īlternatively, if a computer you want to connect with does not have a public IP address – e.g. With TeamViewer Remote, you can wake up a computer directly via its public IP address. Through its built-in WoL capabilities, TeamViewer Remote allows you to turn on offline devices from anywhere. If the MAC address is valid, it powers on or wakes the device. When the WoL-enabled NIC receives the magic packet, it checks it for the correct information. It contains a header and the target device’s media-access-control (MAC) address – a unique identifier assigned to each NIC. The magic packet is designed specifically to be processed quickly and easily by the NIC using very little power. To wake up a target device, the WoL software broadcasts a small data signal known as a "magic packet" to the NIC of the target device, either on the broadcast address for that device’s particular subnet, or on the address for the entire local area network (LAN). in soft-off or hibernate mode), there is sufficient power for the device’s network interface card (NIC) to remain receptive to communications in standby mode. This means that although the rest of the device is powered down (e.g. Originally developed by AMD and Hewlett Packard, WoL is a well-established networking protocol that has been in use since the 1990s.įor Wake-on-LAN software to work, the remote computer you want to control must have its WoL settings enabled.
