To securely enable Directed Broadcasts, access lists should be created or modified to allow them from one or more IP address or subnets and deny them from all others. On most routers Directed Broadcasts are disabled by default due to vulnerabilities associated with them.

Since WOL uses Directed Broadcasts to send Magic Packets to the destination computer, some network configuration may be to necessary wake up computers on a different subnet.

For waking up computers on other subnets, the MAC address and subnet for each computer will be needed and must be updated if a computer is moved to another subnet.

A few free applications available for waking up computers using WOL are provided below. If using a management system such as Microsoft Systems Management Server (SMS), Altiris, or LANDesk, WOL capabilities may be built in or add-ons may be available. If the MAC Address matches the network card, the computer will wake up.įor use in an enterprise, WOL is usually used in conjunction with a management system that already stores this subnet and MAC address information. All computers on the subnet get the packet. A Magic Packet is a broadcast sent on port 0, 7, or 9 that contains the destination computer's MAC address. Once WOL is enabled, the computer can be awakened by sending a Magic Packet.

Click on "Configure" next to the network card the connection is using.

Click on "Network Connection" (in Control Panel) and then click on "Properties.".

In order to enable on the network card, please take the following steps: To see if this is available for you computer, please contact your manufacturer. For example, BIOS settings can be configured remotely on Dell computers using Dell Open Manage and on HP/Compaq computers using Insight Manager. In order to enable WOL in the BIOs quickly and easily, some manufacturers provide methods for managing BIOS settings remotely or through scripts. WOL must be enabled in the both the basic input/output system (BIOS) and the network card.

The listening computer receives this packet, checks it for the correct information, and then boots if the Magic Packet is valid and if contains the network card's MAC address.

The Magic Packet is broadcast on the broadcast address for that particular subnet (or an entire LAN, though this requires special hardware and/or configuration).

The network card listens for a specific packet, called the "Magic Packet.".

The target computer is in standby, hibernate or shutdown, with power reserved for the network card.

Wake-on-LAN (WOL) allows a computer to be powered on or awakened from standby, hibernate or shutdown from another device on a network. With Wake-on-LAN activated, a network administrator can wake up sleeping machines at any time in order to perform on-demand software patches or updates. Please allow time for the computer to wake.Another way to ensure that sleep settings do not interfere with the distribution of administrative software updates (such as Windows security patches and antivirus definitions) is to utilize Wake-on-LAN features. Click the Switch on this computer button to wake the computer. When these conditions are met, any computer in your account that is ready to be woken up will show the Switch on this computer button. You cannot wake a Mac that is powered off.

Please consult your computer's documentation to confirm compatibility.ĭo you want to wake a PC that is powered off?įor a Windows PC that is powered off (but still plugged in), confirm that Wake on LAN is enabled in the computer's BIOS. Stand-by, sleep, or hibernation mode (ACPI specification S3 or S4) are supported. Is your computer in a supported low power mode? At least one of those computers must be powered on. Wake on LAN only works when you are on a network connected to other LogMeIn computers. Under Network, make sure that Enable Wake On LAN from sleep and power off is selected.

Open LogMeIn and choose Options > Preferences > Advanced Settings

Use "Wake on LAN" on to switch on a computer that is in sleep mode (PC or Mac) or powered off (PC).Ĭonfirm the following to ensure that you will be able to use the Wake on LAN feature. How do I wake a computer that is in sleep mode or powered off?
