Wake on Lan Tool Wake-On-LAN Tool Wake on LAN Tool - Available in Standard Edition


The Wake-On-LAN utility of OpUtils software remotely 'wakes-up' (boots up) a machine that is present in the network but not alive. For the tool to work, the PC should be configured to accept the Wake-On-LAN remote command.

Configuring Wake on LAN

BIOS Settings

The Wake-On-LAN functionality is generally disabled by default. The option to enable Wake-On-LAN is different with each computer manufacturer. The most common method adopted across different PC's are as follows:

  1. During the computer’s power-on self-test enter the BIOS setting screen by pressing the F1, INS, or DEL keys.

  2. Select Power settings. Check for Power Up Control.

  3. Enable settings related to Power Up on PCI card, LAN, or Network.

  4. Click Save and exit the BIOS settings.

Operating System (OS) Settings

In some Windows OS, the drivers can enable the Wake ON LAN features of network adapters. For example in Windows 2000, click Power Management tab and under the Adapters properties, select the option Allow this device to bring the computer out of standby.   

 

Alternatively, you can also check the Advanced setting table for parameters related to Wake on LAN and Waking on “Magic Packets” and enable them.

Wake-On-LAN (WOL) Cable

For Wake On LAN to work on computers with older PCI busses, a WOL cable must be installed between the Network Card and the Motherboard.  Because this requires opening the computer case, we advice you to  contact your PC manufacturer for specific instructions.

Enabling Directed Broadcasts on your Network

To send WOL packets from remote networks, the routers must be configured to allow directed broadcasts. To know if the IP broadcast packets have been disabled, check for the line  “no ip directed-broadcast” in the interface configuration. If IP broadcasts are enabled, the line “no ip directed-broadcast” will not be present.

Manually Waking Up a PC from Remote

  1. Click the Tools tab

  2. Choose Wake-On-LAN available under the Network Monitoring category.

  4. You can either manually add the hosts that have to be powered on or choose from the available list. The list is updated based on the input given in the Global Environment settings. Click Add Computers and select the required option.

  5. Based on the option selected above, enter the IP Address of the PC to be powered on, its corresponding MAC Address, and the Subnet Mask or select the hosts from the list. When you are selecting the hosts from the list, if the corresponding subnets of the machines are defined in the Global Environment, the Network Address and the Subnet Mask are automatically added. Else, you have to specify these values by clicking the Apply Subnet Address link before adding the machines from the list.

  6. Click Add. For accurate results ensure

  7. The IP Address is available in the network

  8. The Wake-On-LAN command is enabled in the system. To enable Wake-On-LAN command read the section Configuring Wake-On-LAN.
