Enables specific power management features on the network adapter.
The Enable-NetAdapterPowerManagement cmdlet enables specific power management features on the network adapter. If no power options are specified, then all supported power management features are enabled.
This example enables power management on the network adapter named Ethernet 1 and restarts the network adapter.
This example uses the gets the network adapter named Ethernet 3 and enables power management, then restarts the network adapter.
Manages the address resolution protocol (ARP) offload capability of the network 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.
Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSessionhttp://go.microsoft.com/fwlink/p/?LinkId=227967 or Get-CimSessionhttp://go.microsoft.com/fwlink/p/?LinkId=227966 cmdlet. The default is the current session on the local computer.
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.
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.
Specifies both visible and hidden network adapters should be included. 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.
Specifies the input to this cmdlet. You can use this parameter, or you can pipe the input to this cmdlet.
Specifies the network adapter interface description. 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 .
Specifies the name of the network adapter.
Specifies that the network adapter is not restarted as part of running this cmdlet. Note: Many advanced properties require restarting the network adapter before the new settings take effect.
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.
Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.
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).
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 processor and network adapter.
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.
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.
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 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.
What is receive segment coalescing?

How do I turn off RSC?
Detailed RSC info: RSC equipped vans have a special ABS sensor & tone ring that cannot be modified. If you simply unplug the ABS wire, the van will go into a limp mode. You can turn off the RSC system via the button on the dash, but the “service RSC system” message will chime until it drives you mad.
What is receive side scaling?
When Receive Side Scaling (RSS) is enabled, all of the receive data processing for a particular TCP connection is shared across multiple processors or processor cores. Without RSS, all of the processing is performed by a single processor, resulting in inefficient system cache utilization.

What is d0 packet coalescing?
Packet coalescing is the grouping of packets as a way of limiting the number of receive interrupts and, as a result, lowering the amount of processing required. . an interrupt event message is received, such as a send completion.
What does large send offload do?
In computer networking, large send offload (LSO) is a technique for increasing egress throughput of high-bandwidth network connections by reducing CPU overhead. It works by passing a multipacket buffer to the network interface card (NIC). The NIC then splits this buffer into separate packets.
Should I turn off packet coalescing?
Coalescing the interrupts amounts to a wait which will enhance throughput but degrade latency. Disabling the Interrupt Coalescing and thus forcing the NIC to interrupt the CPU for each packet will provide the minimal latency but lower throughput.

[PSA] How to fix abysmal WiFi speeds on XPS15/13
My XPS15 always had unusable WiFi speeds that seemed to only happen on Windows 10, even after buying an Intel 8260; after months of searching I finally fixed it with this PowerShell command.
Run this command in an administrator PowerShell to fix your Wi-Fi speeds! Disable-NetAdapterRsc -Name Wi-Fi
Doing this boosted my speeds from 0.5/10 to my full 100/10 connection. I'm so relieved right now, after switching out my card, reinstalling Windows, and being resigned to do anything network-heavy on my Fedora partition I finally fixed the one issue with my laptop.
TL;DR: Run this in an admin PowerShell if your WiFi speeds are terrible Disable-NetAdapterRsc -Name Wi-Fi
It disables something called Packet Coalescing. Basically, when your PC receives a network packet (for example, a chunk of data from a file that you're downloading or transferring), it has to process the data (i.e save it onto your hard drive). Without packet coalescing, every time you get a network packet, your system will use something called an "Interrupt", basically it yells at the CPU to come and process the packet asap ("interrupting" it from what it was otherwise doing). This gets the job done, but it can be very inefficient, and can greatly increase CPU usage (particularly with very fast connections, which send packets at much higher rates), and hence we have Packet Coalescing (or as the name implies: "merging" packets together). Basically, when a packet arrives, instead of sending out the interrupt straight away, we can wait for a little bit. If more packets arrive, then we we merge them all together. When the timer runs out, or our mega-packet reaches a certain size, or we receive the last packet for the message/data being sent; then we fire the interrupt and process everything. If we managed to combine multiple packets, then we can process them all in one go, with only a single interrupt — a big saving. This feature can add some of latency (occasionally an issue for i.e online games), but it should actually be improving the transfer speeds (let alone reducing them by this much). So long story short, there's probably a bug in there somewhere (i.e the Windows version of a driver) which is messing things up.
