When using this feature, you may also encounter networking problems that may prevent the device from waking up. On a laptop, you must ensure the device is connected to a power outlet. If you use an Ethernet connection, confirm the lights on the card are still blinking after the device is powered down. The ability to turn on a device remotely only works if the network adapter is active and reachable. You may need to disable fast startup to allow the feature to work. If you use a USB to Ethernet adapter, WoL may only work when the computer is sleeping since powering off the device may also stop providing power to the USB port. If the option is unavailable in the motherboard's BIOS or UEFI or the network adapter (for example, USB to Ethernet adapter), you won't be able to use the feature. The system must support Wake on LAN at the firmware level. If the device does not wake up with these instructions, you can perform a few things to troubleshoot the problem. How to troubleshoot Wake on LAN feature on Windows 10 Once you complete the steps, you can use the addresses with the utility of your choice to wake up a remote computer. If you use Command Prompt, you can query the adapter addresses using the ipconfig /all command. Click the download link to save the app on your device.Warning: Although the app works as advertised, it's a third-party tool, and you should use it only at your own risk. Or you can use third-party tools to send the magic packet to wake up the device.įor the purpose of this guide, we'll use the "WakeMeOnLan" tool from NirSoft to wake a device remotely: You may be able to find scripts that you can use with PowerShell. For instance, you can use the WoL tool built into the router. Once the feature has been configured, you can turn on the computer in multiple ways. How to wake up a computer remotely on Windows 10 In addition to disabling the feature, you may also want to turn off the WoL feature inside the device firmware using your manufacturer's instructions. 9, make sure to select the Disabled option. If you don't want to use the feature, you can use the same instructions outlined above to disable Wake on LAN, but on step No. Many motherboard manufacturers often implement software along with Wake-on-LAN capabilities to offer hassle-free or largely configuration-free usage scenarios.After you complete the steps, the device will be ready for the remote magic packet using a third-party tool. On a secure network, or for basic home use, there shouldn’t be any practical reason to worry. The above image shows the results of a packet sniffer tool used on magic packet, which brings into question exactly how secure they are when used in unsafe networks and over the internet. Magic packets are usually sent over the entirety of a network and contain the subnet information, network broadcast address, and the MAC address of the target computer’s network card, whether Ethernet or wireless. Because your computer is actively listening for a packet, some power is feeding your network card which will result in your laptop’s battery draining faster, so road warriors should take care to turn this off when you need to eke out some extra juice. The typical ports used for WoL magic packets are UDP 7 and 9. These magic packets are sent out by professional software made for any platform, but can also be sent by routers and internet-based websites. Wake-on-LAN-enabled computers essentially wait for a “magic packet” to arrive that includes the network card’s MAC address in it. Anyone who uses a program like VNC or TeamViewer, or keeps a file server or game server program available, should probably have the option enabled for the sake of convenience. This is useful if you plan to access your computer remotely for any reason: it allows you to retain access to your files and programs, while keeping the PC in a low-power state to save electricity (and of course, money). The protocol also allows for a supplementary Wake-on-Wireless-LAN ability as well. The definition of “low power mode” has changed a bit over time, but we can take it to meanwhile the computer is “off” and has access to a power source. Wake-on-LAN (sometimes abbreviated WoL) is an industry-standard protocol for waking computers up from a very low power mode remotely. RELATED: How to Enable Wake-on-LAN in Windows 10 and 11 What Is Wake-on-LAN? Here’s how to enable Wake-on-LAN in Windows 11 and 10. Update, 11/18/21: Wake-on-LAN might be an old-school trick for turning on computers remotely, but it still works. Wake-on-LAN (WoL) has been around for a while, so let’s see how it works and how we can enable it. Technology often yields ridiculous conveniences, like being able to turn on your computer from miles away without pushing the power button.
