This video will guide you on how to check if the driver of your network adapter is working properly. To do this, you need to check if the drivers are properl. Microsoft Network Adapter Multiplexor Protocol should be left unticked. It is only used with NIC Teaming - i.e. Where you have two physical network interfaces that are being used in a load balancing or redundant configuration.
After upgrading Windows, thousands of people are facing this issue of the Microsoft Network Adapter Multiplexor Protocol.
Should you enable it or disable it?
How to gain back connectivity in Windows 10 or any version of Windows?
I found no solution on the internet. So, I had to find one and share it with the world.Worry no more…
It’s a simple 2 minutes process.
This is one of the most popular questions on the internet and there’s not much information about it.
So long story short, after the release of Windows 10, I decided to upgrade my Windows 8.1 to Windows 10.
But as I did not update anything before so I decided to update the Windows instead of downloading its setup and installing it from scratch.
After upgrading it…
I faced one difficulty that I had no connectivity.
I started searching for a fix & came to know that in the WiFi properties, my all connections were unchecked. For getting the connectivity back, I had to check all the boxes.
Please keep in mind that check all the boxes and leave the Microsoft Network Adapter Multiplexor Protocol unchecked. If you do so your connection will work just fine.
What is the Microsoft Network Adapter Multiplexor Protocol?
here is my 17 days research that I am going to share it with you.
If you listen about kernel-mode or not I don’t know if not then I will share the details of kernel mood below also please must read Microsoft Network Adapter multiplexor
The protocol is basically a kernel-mood driver that commonly used with Network Interface card bonding. NIC Teaming is one of the essences of the protocol.
If you know a bit more about NIC teaming then you come to know that it is referred to as Load Balancing/Failover ( LBFO ) that helps you to install one additional ethernet network adapters into your server so that it combines and make one virtual Network interface card and then it will provide you the best performance.
NIC Card in Laptop: Working Explained
Listen as we all know that in the early stages of the technology there are computers that don’t even connect with the other computer easily, so we have to use the floppy disk or something else that is the latest invention of that time.
But nowadays there are multiple ways to do so, Now computers use Network interface cards that have the ability to connect the other computer using Ethernet/WiFi. There are multiple names of the Network Interface card like Network interface controller,
Network Adapter, or Local Area Network Adapter that we know as LAN.
At starting releases of this NIC there are separate NIC that consisted of a card that is connected with the motherboard of the computer. And an Rj45 connector is used to connect it with other PC.
How to Configure the Microsoft Network Adapter Multiplexor protocol?
Here is the method of this according to my expert research.
Method 1:
Firstly You have to disable the Windows Firewall that can be disabled by just going into settings & disable all the features that are constantly running on the background.
If you turn off your Windows Firewall it is dangerous for you but you are doing it just for experiment purposes. After completing the test please re-enable it to protect the network.
Here is the video for the configuration of the Microsoft Network Adapter Multiplexor protocol.
How to disable Microsoft Network Adapter Multiplexor Protocol?
This is very easy I just show you by putting images here that how to disable Microsoft Network Adapter Multiplexor Protocol in Windows 10.
After clicking the wifi settings you got this window, now you have to click on to Change Adapter Options that are on the top right corner of the window.
The Next Window that will appear in front of you is similar to this one.
Now you have to right-click on the network that is connected to your PC & the next window pop up like this you can see below
So here you can see the uncheck option is Microsoft Network Adapter Multiplexor Protocol so if you uncheck it that’s mean it is disabled but if you check it then It is enabled so by choosing what you want & just click on Ok.
Here is also a Video Guide that I found for you please have a look if you face any difficulty just comment below I am happy to help. I wanna thank Web Design Columbia SC for helping me find the solution.
Microsoft Network Adapter Multiplexor Protocol Hyper-V – Some Misconceptions!
I will demonstrate how to install Hyper-v and create virtual machines.
I will also demonstrate how to manage and maintain those virtual machines once they have been created.
I will provide you with an overview of hyper-v as well as some of the background behind the technology.
I will also provide you with some hyper-v terminology and will briefly touch on licensing so let’s get started.
The question you may have is what exactly is hyper-v. Hyper-v is a Microsoft virtualization product that allows you to create a virtual machine on your system that running windows.
In the past when someone needs another Virtual machine they have to purchase the computer hardware itself including the chassis, motherboard processor, RAM, hard disks so on and so forth once the hardware was in place you would have to purchase a Windows server operating system that has to be installed onto the computer hardware.
After making one if you decided to deploy another Windows server you would have to purchase a second computer and a second Windows operating system.
When hardware became faster and more powerful a new concept is known as dual booting was introduced.
Dual-booting gave IT professionals the ability to install multiple operating systems onto one physical computer whilst dual booting.
Let’s take a modern-day example and say that you have a computer and a copy of Windows 7 and Windows 8.1 you want to install both of these operating systems onto your one computer to do this you create two partitions on the hard disk Windows 7 is installed onto the first partition and Windows 8.1 onto the second partition.
When the computer is first switched on you are given the choice of which operating system you’d like to boot up however you can only use one of those systems at a time what this essentially means is that if you are using Windows 7 and wanted to use Windows 8.1 you would first have to shut Windows 7 down and then boot up Windows 8.1 for a few years.
Dual-booting was the only method of running two or more operating systems on the same physical computer before the virtualization was introduced addressed many of the shortcomings of dual-booting by allowing you to create virtual machines.
Virtual machines as I like to describe them are essentially software computers that are your machine looks and behaves just like any other software application that you have installed on your computer every day.
The virtual machine you create provide you with a completely separate working operating system this essentially means that you can have multiple operating systems running side-by-side on the same computer at the same time when the
hyper-v role is installed onto a Windows Server 2012 or Windows Server 2012 r2
A server that server becomes known as the host and the virtual machines you create on the host are called guests once a virtual machine or guest installed.
One thing, you should also know that hyper-v, guest compatible with a range of operating systems with Windows Server 2012 and Windows Server 2012 r2 you can install the following Microsoft server operating systems as hyper-v guests.
Windows Server 2012 r2, Windows Server 2012, Windows Server 2008 r2, Windows Server 2008, Windows Server 2003 r2 and Windows Server 2003 providing you have service pack 2 installed, So you can also have Windows Home Server 2011 and windows small business server 2011.
You can check the Video for more info.

You can use this topic to learn some of the features of network adapters that might affect your purchasing choices.
Network-intensive applications require high-performance network adapters. This section explores some considerations for choosing network adapters, as well as how to configure different network adapter settings to achieve the best network performance.
Tip
You can configure network adapter settings by using Windows PowerShell. For more information, see Network Adapter Cmdlets in Windows PowerShell.
Offload Capabilities
Offloading tasks from the central processing unit (CPU) to the network adapter can reduce CPU usage on the server, which improves the overall system performance.
The network stack in Microsoft products can offload one or more tasks to a network adapter if you select a network adapter that has the appropriate offload capabilities. The following table provides a brief overview of different offload capabilities that are available in Windows Server 2016.
Offload type | Description |
---|---|
Checksum calculation for TCP | The network stack can offload the calculation and validation of Transmission Control Protocol (TCP) checksums on send and receive code paths. It can also offload the calculation and validation of IPv4 and IPv6 checksums on send and receive code paths. |
Checksum calculation for UDP | The network stack can offload the calculation and validation of User Datagram Protocol (UDP) checksums on send and receive code paths. |
Checksum calculation for IPv4 | The network stack can offload the calculation and validation of IPv4 checksums on send and receive code paths. |
Checksum calculation for IPv6 | The network stack can offload the calculation and validation of IPv6 checksums on send and receive code paths. |
Segmentation of large TCP packets | The TCP/IP transport layer supports Large Send Offload v2 (LSOv2). With LSOv2, the TCP/IP transport layer can offload the segmentation of large TCP packets to the network adapter. |
Receive Side Scaling (RSS) | RSS is a network driver technology that enables the efficient distribution of network receive processing across multiple CPUs in multiprocessor systems. More detail about RSS is provided later in this topic. |
Receive Segment Coalescing (RSC) | RSC is the ability to group packets together to minimize the header processing that is necessary for the host to perform. A maximum of 64 KB of received payload can be coalesced into a single larger packet for processing. More detail about RSC is provided later in this topic. |
Receive Side Scaling
Windows Server 2016, Windows Server 2012, Windows Server 2012 R2, Windows Server 2008 R2, and Windows Server 2008 support Receive Side Scaling (RSS).
Some servers are configured with multiple logical processors that share hardware resources (such as a physical core) and which are treated as Simultaneous Multi-Threading (SMT) peers. Intel Hyper-Threading Technology is an example. RSS directs network processing to up to one logical processor per core. For example, on a server with Intel Hyper-Threading, 4 cores, and 8 logical processors, RSS uses no more than 4 logical processors for network processing.
RSS distributes incoming network I/O packets among logical processors so that packets which belong to the same TCP connection are processed on the same logical processor, which preserves ordering.
RSS also load balances UDP unicast and multicast traffic, and it routes related flows (which are determined by hashing the source and destination addresses) to the same logical processor, preserving the order of related arrivals. This helps improve scalability and performance for receive-intensive scenarios for servers that have fewer network adapters than they do eligible logical processors.
Configuring RSS
In Windows Server 2016, you can configure RSS by using Windows PowerShell cmdlets and RSS profiles.
You can define RSS profiles by using the –Profile parameter of the Set-NetAdapterRss Windows PowerShell cmdlet.
Windows PowerShell commands for RSS configuration
The following cmdlets allow you to see and modify RSS parameters per network adapter.
Note
For a detailed command reference for each cmdlet, including syntax and parameters, you can click the following links. In addition, you can pass the cmdlet name to Get-Help at the Windows PowerShell prompt for details on each command.
- Disable-NetAdapterRss. This command disables RSS on the network adapter that you specify.
- Enable-NetAdapterRss. This command enables RSS on the network adapter that you specify.
- Get-NetAdapterRss. This command retrieves RSS properties of the network adapter that you specify.
- Set-NetAdapterRss. This command sets the RSS properties on the network adapter that you specify.
RSS profiles
You can use the –Profile parameter of the Set-NetAdapterRss cmdlet to specify which logical processors are assigned to which network adapter. Available values for this parameter are:
- Closest. Logical processor numbers that are near the network adapter's base RSS processor are preferred. With this profile, the operating system might rebalance logical processors dynamically based on load.
- ClosestStatic. Logical processor numbers near the network adapter's base RSS processor are preferred. With this profile, the operating system does not rebalance logical processors dynamically based on load.
- NUMA. Logical processor numbers are generally selected on different NUMA nodes to distribute the load. With this profile, the operating system might rebalance logical processors dynamically based on load.
- NUMAStatic. This is the default profile. Logical processor numbers are generally selected on different NUMA nodes to distribute the load. With this profile, the operating system will not rebalance logical processors dynamically based on load.
- Conservative. RSS uses as few processors as possible to sustain the load. This option helps reduce the number of interrupts.
Depending on the scenario and the workload characteristics, you can also use other parameters of the Set-NetAdapterRss Windows PowerShell cmdlet to specify the following:
- On a per-network adapter basis, how many logical processors can be used for RSS.
- The starting offset for the range of logical processors.
- The node from which the network adapter allocates memory.
Following are the additional Set-NetAdapterRss parameters that you can use to configure RSS:
Note
In the example syntax for each parameter below, the network adapter name Ethernet is used as an example value for the –Name parameter of the Set-NetAdapterRss command. When you run the cmdlet, ensure that the network adapter name that you use is appropriate for your environment.
- * MaxProcessors: Sets the maximum number of RSS processors to be used. This ensures that application traffic is bound to a maximum number of processors on a given interface. Example syntax:
Set-NetAdapterRss –Name 'Ethernet' –MaxProcessors <value>
- * BaseProcessorGroup: Sets the base processor group of a NUMA node. This impacts the processor array that is used by RSS. Example syntax:
Set-NetAdapterRss –Name 'Ethernet' –BaseProcessorGroup <value>
- * MaxProcessorGroup: Sets the Max processor group of a NUMA node. This impacts the processor array that is used by RSS. Setting this would restrict a maximum processor group so that load balancing is aligned within a k-group. Example syntax:
Set-NetAdapterRss –Name 'Ethernet' –MaxProcessorGroup <value>
- * BaseProcessorNumber: Sets the base processor number of a NUMA node. This impacts the processor array that is used by RSS. This allows partitioning processors across network adapters. This is the first logical processor in the range of RSS processors that is assigned to each adapter. Example syntax:
Set-NetAdapterRss –Name 'Ethernet' –BaseProcessorNumber <Byte Value>
- * NumaNode: The NUMA node that each network adapter can allocate memory from. This can be within a k-group or from different k-groups. Example syntax:
Set-NetAdapterRss –Name 'Ethernet' –NumaNodeID <value>
- * NumberofReceiveQueues: If your logical processors seem to be underutilized for receive traffic (for example, as viewed in Task Manager), you can try increasing the number of RSS queues from the default of 2 to the maximum that is supported by your network adapter. Your network adapter may have options to change the number of RSS queues as part of the driver. Example syntax:
Set-NetAdapterRss –Name 'Ethernet' –NumberOfReceiveQueues <value>

Understanding RSS Performance
Tuning RSS requires understanding the configuration and the load-balancing logic. To verify that the RSS settings have taken effect, you can review the output when you run the Get-NetAdapterRss Windows PowerShell cmdlet. Following is example output of this cmdlet.
In addition to echoing parameters that were set, the key aspect of the output is the indirection table output. The indirection table displays the hash table buckets that are used to distribute incoming traffic. In this example, the n:c notation designates the Numa K-Group:CPU index pair that is used to direct incoming traffic. We see exactly 2 unique entries (0:0 and 0:4), which represent k-group 0/cpu0 and k-group 0/cpu 4, respectively.
There is only one k-group for this system (k-group 0) and a n (where n <= 128) indirection table entry. Because the number of receive queues is set to 2, only 2 processors (0:0, 0:4) are chosen - even though maximum processors is set to 8. In effect, the indirection table is hashing incoming traffic to only use 2 CPUs out of the 8 that are available.
To fully utilize the CPUs, the number of RSS Receive Queues must be equal to or greater than Max Processors. In the previous example, the Receive Queue should be set to 8 or greater.
NIC Teaming and RSS
RSS can be enabled on a network adapter that is teamed with another network interface card using NIC Teaming. In this scenario, only the underlying physical network adapter can be configured to use RSS. A user cannot set RSS cmdlets on the teamed network adapter.
Receive Segment Coalescing (RSC)
Receive Segment Coalescing (RSC) helps performance by reducing the number of IP headers that are processed for a given amount of received data. It should be used to help scale the performance of received data by grouping (or coalescing) the smaller packets into larger units.
This approach can affect latency with benefits mostly seen in throughput gains. RSC is recommended to increase throughput for received heavy workloads. Consider deploying network adapters that support RSC.
On these network adapters, ensure that RSC is on (this is the default setting), unless you have specific workloads (for example, low latency, low throughput networking) that show benefit from RSC being off.
Understanding RSC Diagnostics
You can diagnose RSC by using the Windows PowerShell cmdlets Get-NetAdapterRsc and Get-NetAdapterStatistics.
Microsoft Network Adapter Multiplexor Enable Password
Following is example output when you run the Get-NetAdapterRsc cmdlet.
The Get cmdlet shows whether RSC is enabled in the interface and whether TCP enables RSC to be in an operational state. The failure reason provides details about the failure to enable RSC on that interface.
In the previous scenario, IPv4 RSC is supported and operational in the interface. To understand diagnostic failures, one can see the coalesced bytes or exceptions caused. This provides an indication of the coalescing issues.
Microsoft Network Adapter Multiplexor Enable Windows 10
Following is example output when you run the Get-NetAdapterStatistics cmdlet.
RSC and Virtualization
RSC is only supported in the physical host when the host network adapter is not bound to the Hyper-V Virtual Switch. RSC is disabled by the operating system when the host is bound to the Hyper-V Virtual Switch. In addition, virtual machines do not get the benefit of RSC because virtual network adapters do not support RSC.
RSC can be enabled for a virtual machine when Single Root Input/Output Virtualization (SR-IOV) is enabled. In this case, virtual functions support RSC capability; hence, virtual machines also receive the benefit of RSC.
Network Adapter Resources
Microsoft Network Adapter Multiplexor Protocol Enable Or Disable
A few network adapters actively manage their resources to achieve optimum performance. Several network adapters allow you to manually configure resources by using the Advanced Networking tab for the adapter. For such adapters, you can set the values of a number of parameters, including the number of receive buffers and send buffers.
Configuring network adapter resources is simplified by the use of the following Windows PowerShell cmdlets.
For more information, see Network Adapter Cmdlets in Windows PowerShell.
