- How To Configure Wake On LAN on Windows. Using WOL (Wake On LAN) it is possible to wake up your computer using the Unified Remote app. However, this feature is typically not enabled by default.
- Native Windows 10 Universal WOL tool. Easy WOL allows to 'wake up' compatible PCs and other devices by sending a specially crafted 'Magic Packet' to your network. To wake up a device on a local network all you need to provide is the MAC address. Easy WOL will calculate broadcast address and send WOL packet to all devices on your local network.

Subnet-Directed Broadcast. This is the first type of WoL in ConfigMgr and is the traditional WoL. The WOL packet will be sent as a broadcast to all devices on the network. You can execute this line in the terminal, or use a simple bash script to open instead, that will do this for you #!/bin/bash echo 'Going to wake up your PC' sudo etherwake-i eth0 AA:BB:CC:DD:EE:FF.

This article explains why unwanted wake-up events occur when you enable the Wake On LAN (WOL) functionality in Windows 7 and in Windows Vista, and describes how to configure the computer to wake only in response to a Magic Packet.

Introduction
In Windows 7 and in Windows Vista, the WOL feature can wake a remote computer from a power-saving state such as sleep. When you enable WOL, the network adapter continues listening to the network when the computer is asleep. WOL wakes the computer if it receives a special data packet.
One kind of special data packet contains a wake-up pattern. By default, Windows 7 and Windows Vista listen for the following packets when you enable WOL:
- A directed packet to the MAC address of the network adapter
- A NetBIOS name resolution broadcast for the local computer name
- An Address Resolution Protocol (ARP) packet for the IPv4 address of the network adapter
- An IPv6 Neighbor Discovery packet for the network adapter's solicited-node multicast addressA Magic Packet can also wake a remote computer.
A Magic Packet is a standard wake-up frame that targets a specific network interface.
In most cases, a wake-up pattern or a Magic Packet enables remote access to a computer that is in a power-saving state. However, some networking protocols use these packets for other purposes. For example, routers use ARP packets to periodically confirm the presence of a computer. Such protocols do not use these packets to wake computers. However, in some networks, network traffic may wake up a remote computer by mistake. These unwanted wake-up events may occur in especially noisy environments such as enterprise networks. Therefore, by default, WOL is disabled in Windows 7 and in Windows Vista.
More information
WOL can be an effective way to conserve power while keeping a computer reachable on the network.
However, unwanted wake events may occur after you enable WOL. For example, the computer may wake up soon after it enters a power-saving state. One cause may be that the network environment generates wake-up patterns too frequently. In this situation, we strongly recommend that you configure the computer to wake only in response to Magic Packets. Magic Packets are especially designed to wake up a computer from a power-saving state. Also, because a Magic Packet is specific to the MAC address of a network adapter, a Magic Packet is unlikely to be sent accidentally.
To configure Windows 7 in this manner, follow these steps:
- Click Start, type Network and Sharing Center in the Start Search box, and then press Enter.
- On the Tasks bar, click Change adapter settings.
- Right-click the network adapter that you want to configure, and then click Properties. For example, right-click Local Area Connection, and then click Properties.
- If you are prompted for an administrator password or for confirmation, type the password or provide confirmation.
- Click Configure.
- If the network adapter supports WOL, click to select the Allow this device to wake the computer check box on the Power Management tab, select the Only allow a magic packet to wake the computer check box, and then click OK.
To configure Windows Vista in this manner, follow these steps:
- Click Start, type Network and Sharing Center in the Start Search box, and then press Enter.
- On the Tasks bar, click Manage network connections.
- Right-click the network adapter that you want to configure, and then click Properties. For example, right-click Local Area Connection, and then click Properties.
- If you are prompted for an administrator password or for confirmation, type the password or provide confirmation.
- Click Configure.
- If the network adapter supports WOL, select the Allow this device to wake the computer check box on the Power Management tab, select the Only allow management stations to wake the computer check box, and then click OK.
You may also have to enable BIOS settings to enable WOL. The specific BIOS settings depend on the manufacturer of the computer.
