The Wake on Wireless LAN implementation in Windows 7 represents a superset of Wake on LAN. Low Power on Media Disconnect is disabled when the computer goes to sleep.

The computer will automatically detect when the cable is plugged in again and return the network adapter to full power. When Windows detects that media has been disconnected (for example, a cable is unplugged), Windows will put the device into the low power state and disable the LAN. Lower Power on Media Disconnect is the ability of the network adapter to go to sleep when it is not in use.

Both the hardware and the driver must support NS offload to enable this feature. NS offload is the ability of the network adapter to respond to a Neighbor Discovery Neighbor Solicitation request with a Neighbor Advertisement without waking the computer. Both the hardware and the driver must support ARP offload to enable this feature. ARP offload is the ability of the network adapter to respond to an IPv4 ARP request without waking the computer. Windows 7 adds support for ARP and NS network presence offloads.ĪRP offload. The patterns that are chosen by default are based on the network adapter’s capabilities and whether the computer is joined to a domain as follows:Ĭapabilities supported by the network adapterĭefault for a computer that is joined to a domainĭefault for a computer that is not joined to a domain Magic packet is used by some applications including most media sharing applications. The magic packet is always supported and does not need or use a pattern. If there is a match, the network adapter wakes the computer. As network packets are received, they are masked using the bitmap mask and then compared to the pattern filter. Bitmapped patterns are defined by a bitmap mask and a pattern filter. Most network adapters can be programmed with bitmapped pattern filters. Wake on new incoming TCP connection for IPv4 and IPv6 (TCP SYN IPv4 and TCP SYN IPv6).īitmapped Patterns.
The following wake patterns may be supported by a network adapter: You can enable these patterns on the network adapter. Wake patterns refer to network packet filters that determine if incoming network traffic should wake the computer. This section outlines the technical details of the power. In this guideĬonfiguring power management using the user interfaceĬonfiguring Wake on LAN using the command lineĬonfiguring power management using keywordsĬonfiguring power management using the WMI API Users, IT Professionals, and OEMs that are interested in understanding and configuring the networking power management enhancements in Windows 7. This helps enterprise and home computers to save energy by entering into sleep mode when they are not in use. These enhancements in Windows 7 improve the ability of the operating system to stay asleep while still maintaining a network presence. This feature is only available when supported by the network adapter. This is a new Windows 7 feature that enables the computer to save energy by placing the network adapter in the low power state when the LAN cable is unplugged and the computer is running. Support for these offloads depends on the network adapter and driver (NDIS 6.20) and may not be available on older hardware. By offloading ARP and NS responses to the network adapter, the computer is no longer woken up merely to maintain network presence. ARP and NS protocols are commonly used to verify whether a computer is still present on the network, often without actually needing to access the computer. ARP and NS protocols map Internet Protocol (IP) addresses to a MAC address. In addition to more targeted wake patterns, Windows 7 adds support for Address Resolution Protocol (ARP) and Neighbor Solicitation (NS) offloads. Windows 7 does not wake on directed packets (for example, ping) which have been known to cause frequent and unnecessary wakes. The Wake on LAN patterns in Windows 7 were designed to ensure that the computer wakes when accessed by the network while minimizing spurious wakes. What’s new in the Networking Power Management?Įnhancements in Windows 7 have been made in the areas of Wake on LAN, Wake on Wireless LAN and Low Power on Media Disconnect (sometimes referred to as D3 on disconnect).

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. Wake on LAN allows the computer to be woken up from sleep by desired network traffic. For example, the most common networking power management feature is Wake on LAN (sometimes referred to as WoL). Networking power management refers to the set of features that you can configure to allow the computers in your network to save energy. Applies To: Windows 7 What is Networking Power Management?
