This post describes how I fixed my Wake-On-LAN problem using the powercfg tool. My Toshiba Satellite A505-S6986 wouldn’t respond to magic packets sent over the network.

Before using powercfg, I first checked the following:

1. Wake-On-LAN was enabled in the BIOS.
2. All settings related to Wake-On-LAN were enabled in the adapter’s Advanced properties tab:
   • Shutdown Wake-On-Lan
   • Wake on Magic Packet
   • Wake on pattern match
     
3. All wake-related settings were checked on the Power Management properties tab:
   • Allow this device to wake computer
   • Only allow a magic packet to wake the computer
     

Even with these settings configured properly, my laptop still wouldn’t respond to magic packets.
First, I opened a command prompt as administrator. A regular user doesn’t have the access rights to change power options.

Then, I checked to see if the LAN adapter is in the list of devices which can wake Windows:

C:\Windows\system32>powercfg -devicequery wake_armed
HID Keyboard Device (002)
HID-compliant mouse (001)
Logitech USB Wheel Mouse (004)

The Ethernet adapter isn’t in there, so I looked at the list of wake-programmable devices in order to find out the name of my LAN adapter:

C:\Windows\system32>powercfg -devicequery wake_programmable
HID-compliant device
Realtek PCIe FE Family Controller            <=== LAN adapter
HID Keyboard Device (002)
TOSHIBA Software Modem
HID-compliant mouse (001)
HID-compliant consumer control device (001)
Logitech USB Wheel Mouse (004)

Finally, I enabled wake for my Ethernet device, using the name "Realtex PCIe FE Family Controller":

C:\Windows\system32>powercfg -deviceenablewake "Realtek PCIe FE Family Controller"

(if you see an error like, "Invalid Parameters -- try "/?" for help," it most likely means that you mistyped the device name)

I am now able to wake my laptop from sleep and hibernate modes using the Wake On Lan app for my Android device.

The “iTunes COM SDK for Windows” archive from the Apple Developer Center contains files which are marked as encrypted. Shortly after extracting the files to my libraries folder, I was surprised to receive a popup dialog from Windows 7, “Encrypting File System,” which prompted me to back up my encryption certificate and key:

I used CIPHER.EXE to verify that the only encrypted contents on the volume were those of the Apple download:

C:\lib>cipher /u /n

To fix this, I opened the properties for the iTunesCOMWindowsSDK folder, selected the General tab, clicked Advanced, and unselected “Encrypt contents to secure data”:

The Apple iTunes SDK (“iTunes COM SDK for Windows”) is astonishingly difficult to find. It can be found on the Dowloads & ADC Program Assets (connect.apple.com) page. In the “Downloads” box on the right, click on “Developer Tools,” then search the page for “iTunes COM SDK for Windows.”

The irritating thing is that there seems to be no direct path from the Apple Developer’s Center to this “Downloads & ADC Program Assets” page.
