Description

The Disable-NetAdapterPowerManagement cmdlet disables specific power management features on a network adapter. If no power parameters are specified then all power management features are disabled.

Examples

Example 1: Disable power management on a specified network adapter

PS C:\> Disable-NetAdapterPowerManagement -Name "Ethernet 1"

This command disables power management on the network adapter named Ethernet 1 and restarts the network adapter.

Example 2: Disable power management on a specified network adapter using InputObject

PS C:\> $NetAdapter1 = Get-NetAdapter -Name "Ethernet 3"
PS C:\> Disable-NetAdapterPowerManagement -InputObject $NetAdapter1

This first command gets the network adapter named Ethernet 3 and stores the result in the variable named $NetAdapter1.

The second command disables the network adapter that is in the $NetAdapter1 variable.

Example 3: Disable power management on the specified network adapter and do not restart it

PS C:\> Disable-NetAdapterPowerManagement -Name "Ethernet 4" -NoRestart

This command disables power management on the network adapter named Ethernet 4 and specifies that the network adapter is not restarted.

Parameters

-ArpOffload

Indicates that the cmdlet manages the address resolution protocol (ARP) offload capability of the adapter.

The computer, when in low power mode using the ARP offload technology, is able to offload the responsibility of handling responses for incoming ARP protocol requests.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet. For more information about Windows PowerShell® background jobs, see about_Jobs.

Type:	SwitchParameter
Position:	Named
Default value:	None

Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:	SwitchParameter
Aliases:	cf
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-D0PacketCoalescing

Indicates that the cmdlet manages the D0 packet coalescing capability of the network adapter.

This feature enables power saving on the computer by reducing the number of receive interrupts. This reduces the number of receive interrupts by coalescing random broadcast or multicast packets. The processing overhead and power consumption is significantly reduced on the computer.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-DeviceSleepOnDisconnect

Indicates that the cmdlet manages the device sleep on disconnect capability of the network adapter.

This feature allows the device to stand-by in a low power mode when media is disconnected and wake when media is connected again.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-IncludeHidden

Indicates that the cmdlet includes both visible and hidden network adapters in the operation. By default only visible network adapters are included. If a wildcard character is used in identifying a network adapter and this parameter has been specified, then the wildcard string is matched against both hidden and visible network adapters.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-InputObject

Specifies the input to this cmdlet. You can use this parameter, or you can pipe the input to this cmdlet.

Type:	CimInstance[]
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-InterfaceDescription

Specifies an array of network adapter interface descriptions. For a physical network adapter this is typically the name of the vendor of the network adapter followed by a part number and description, such as Contoso 12345 Gigabit Network Device.

Type:	String[]
Aliases:	ifDesc, InstanceID
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-Name

Specifies an array of network adapter names.

Type:	String[]
Aliases:	ifAlias, InterfaceAlias
Position:	0
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-NoRestart

Indicates that the cmdlet does not restart the network adapter after completing the operation. Many advanced properties require restarting the network adapter before the new settings take effect.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-NSOffload

Indicates that the cmdlet manages the neighbor solicitation (NS) offload capability of the network adapter.

The computer, when in low power mode using the NS offload technology, is able to offload the handling of responses for incoming NS protocol requests.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-RsnRekeyOffload

Indicates that the cmdlet manages the Wi-Fi robust security network (RSN) rekey offload capability of the network adapter.

The computer, when it goes into sleep state, is able to offload the group temporal key (GTK) rekeying for wake on wireless LAN (WoWLAN).

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-SelectiveSuspend

Indicates that the cmdlet manages the selective suspend capability of the network adapter.

The network drive interface specification (NDIS) selective suspend interface allows NDIS to suspend an idle network adapter by transitioning the adapter to a low-power state. This enables the computer to reduce the power overhead on the CPU and network adapter.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-ThrottleLimit

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

Type:	Int32
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-WakeOnMagicPacket

Indicates that the cmdlet manages the wake on magic packet capability of the network adapter.

The magic packet is a broadcast frame containing anywhere within its payload 6 bytes of all 255 (FF FF FF FF FF FF) in hexadecimal), followed by sixteen repetitions of the 48-bit MAC address of the target computer, for a total of 102 bytes.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-WakeOnPattern

Indicates that the cmdlet manages the wake on pattern capability of the network adapter.

A wake pattern refers to network packet filters that determine if incoming network traffic should wake the computer. These patterns can be enabled on the network adapter.

The following wake patterns may be supported by a network adapter:

• Wake Pattern
• Wake on new incoming TCP connection for IPv4 and IPv6 including TCP SYN IPv4 and TCP SYN IPv6.
• 802.1x re-authentication packets
• Bitmapped Patterns. Most network adapters can be programmed with bit-mapped pattern filters. Bitmapped patterns are defined by a bit-map mask and a pattern filter. As a network packet is received, it is masked using the bitmap mask and then compared to the pattern filter. If there is a match, then the network adapter wakes the computer.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

Type:	SwitchParameter
Aliases:	wi
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False
