The Wake-on-LAN (WoL) feature allows you to turn on/awake your computer when it is in sleep mode. [ Note: Currently this feature doesn't works for hibernate mode on Desktop Connect]
To configure WoL you must have your computer "Saved". This can be done by selecting the computer, choosing "Settings" and then under the Discovered Computer section choose "save entry permanently".
Configuration of Wake on LAN: Follow these steps configure and use the WoL feature:
1. Click the name of the desired computer under "Saved " section.
2. Hit the " Settings " button.
3. Choose " Wake on Lan".
4. Provide the correct MAC Address, hostname ( we prefer IP Address here ) , Netmask, and Port Number. Please see WoL C
onfiguration Information below for instructions on how to find these for your computer.
5. Hit " wake up computer " then go back and save the settings.
6. Now you can easily turned on or wake up your desired saved computer using " Connect" button.
Once configured for WoL Desktop Connect will automatically awake the saved computer when you attempt to connect to it. To change this default to not send a WoL packet the computer when you connect please follow these instructions:
1. Go to " Preferences" .
2. Choose " Wake computer before connecting" to remove the checkmark showing it is enabled.
Troubleshooting:
1) My computer does not wake up when I send a WoL request.
Your computer MUST be connected through an Ethernet Cable. Wake on LAN is not available on a wireless/Wi-Fi network.
2) My computer does not show the WoL configuration under Settings.
You must have the computer "Saved". It will otherwise only appear when it is powered on through Shared or Easy Connect which is why a Wake on LAN option is not presented.
3) WoL Configuration Information: How to obtain the specific details for your computer to bring it out of sleep mode.
This section explains how to obtain the information required for the Wake on Lan (WoL) feature. It will explain how to obtain your MAC Address, Netmask, and IP Address of your computer.
For Macintosh:
1. MAC Address: This is a good link to know MAC Address for your MAC operating system ( http://www-dcn.fnal.gov/DCG-Docs/mac/ ) . Please choose your operating system in the given link.
2. Subnet mask [ also called Netmask ] and IP Address: Open " System Prefernces" and select Network. Click " advanced" button. Then choose " TCP/IP " tab as shown in the figure below :

Users can see and obtain the IP Address and Subnet Mask of their computer on following the above steps.
For Windows [ Windows 95 and later ]:

For Linux:
For Example:
# ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:60:08:C4:99:AA
inet addr:131.225.84.67 Bcast:131.225.87.255 Mask:255.255.248.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:15647904 errors:0 dropped:0 overruns:0
TX packets:69559 errors:0 dropped:0 overruns:0
Interrupt:10 Base address:0x300
The MAC Address is the " HWaddr " listed on the first line. In the case of this machine , it is 00:60:08:C4:99:AA .
The Subnet mask is the " Mask " listed on the end of the second line. In the cae of this machine , it is 255.255.248.0
The IP Address is the " inet addr " on the second line. In the cse of this machine, it is 131.225.84.67
For Solaris/ SunOS:
1. MAC Address, Subnet Mask, and IP Address : In order to find the MAC Address, Subnet Mask, and IP Address on Solaris platofrm, users must first become root, through the use of su. Then, type ifconfig -a and look up the relevant info. For Example:
# ifconfig -a
le0: flags=863<UP,BROADCAST,NOTRAILERS,RUNNING,MULTICAST> mtu 1500
inet 131.225.80.209 netmask fffff800 broadcast 131.225.87.255
ether 8:0:20:10:d2:ae
The MAC Address is the " ether" listed on the third line. In the case of this machine , it is 08:00:20:10:d2:ae [ Note: .Solaris and SunOS strip off the leading 0 commonly included in the MAC Address. ]
The Subnet mask is the " netmask " listed on the second line. In the cae of this machine , it is fffff800
The IP Address is the " inet " on the second line. In the cse of this machine, it is 131.225.80.209
INDEPENDENT TEST:
You may find it useful to use an internet link from your iPad to test awakening your computer to make sure you have the proper information configured.
For example,
