I had a lot of trouble with drivers on my Windows 7 64-bit computer setup which exacerbated my trouble with WOL. I had trouble locating the exact procedure and settings for enabling the WOL so that I could wake my computer remotely using my Windows Home Server (WHS). I use the AutoExit utility addin to WHS.
My main misinterpretation was the network adapter setting that stated Allow the computer to turn off this device to save power. Well … I wanted the network to have standby power for the WOL … so I didn’t want it turned off. Unfortunately, it appears that this is just poor wording on Microsoft’s part as Microsoft’s website states “When checked, power management is enabled on the network adapter”, which is, in fact, exactly what I wanted to do!
So this blog is intended to help any other poor sod with who is befuddled with WOL (particularly on the Asus P7P55D – but it probably applies to the other boards in the series and many other similar boards will have similar settings).
- Update BIOS settings to ensure that the on-motherboard Network adapter can “talk” to the “system.” The diagram below is not the P7P55D (because ASUS does not release circuit diagrams), however I believe their circuitry is similar. So the LAN connects to the system through the PCIe bus.
- Enter the BIOS by selecting Del during power on splash screen
- Use cursor to select Power menu
- Select APM Configuration
- Enable Power On By PCIE Devices
- Select F10 and OK to save and exit, and allow Windows to start
- Log in, if required
- Start the Device Manager
- Select Network Adapters
- Right click the network adapter and select Properties
- Go to the Advanced tab
- Scroll down to Wake on Magic Packet and select value “Enabled.” For debug purposes potentially enable other settings like Wake on pattern match, Shutdown Wake-On-LAN etc. that are specific to your adapter.
- Select the Power Management tab
- Check the Allow the computer to turn off this device to save power check box
- Check the Allow this device to wake the computer check box
- Check Only allow a magic packet to wake the computer check box
- Click OK.
What is Networking Power Management? Networking power management refers to the set of features that you can configure to allow the computers in your network to save energy. For example, the most common networking power management feature is Wake on LAN (sometimes referred to as WoL or WOL). Wake on LAN allows the computer to be woken up from sleep by desired network traffic. This paper describes the networking power management capabilities of Windows 7, how to use them, and what controls you can use to customize their behavior.
Configuring power management using the user interface
To turn power management features on or off:
- Open Network and Sharing Center (click the Start button, type Network and Sharing in the Start Search box, and press Enter).
- Click the Change adapter settings link in the upper left of the navigation pane.
- Right click the network connection you want to enable/disable power management support on and click Properties.
- Click Configure.
- On the Power Management tab, check or clear the Allow the computer to turn off this device to save power check box.
- When checked, power management is enabled on the network adapter.
- When cleared, power management is disabled on the network adapter.
- You can enable Wake on LAN for all wake methods or just enable magic packet WoL:
- To enable Wake on LAN for all methods, check the Allow this device to wake the computer check box.
- To enable Wake on LAN for magic packet only, check the Allow this device to wake the computer check box and then check Only allow a magic packet to wake the computer check box.
- Click OK.
