What is Microsoft Network Adapter Multiplexor Protocol

There have been questions about the Microsoft network adapter multiplexor protocol and if it should be enabled or disabled. This feature is usually in the “Items this connection uses” list. You can find it when you go to the Wifi Properties. By default, the option is often usually off for many users. Being disabled is what often gets users in a dilemma asking themselves if disabling or enabling the feature might have an effect on their connection or bandwidth.

The problem usually comes up when you want to enable it. When the other options on the list are on, it is very difficult to enable the protocol. It is almost impossible.

What is the Microsoft Adapter Multiplexor Protocol?

Microsoft Adapter Multiplexor Protocol is simply a special set of settings and configurations by Microsoft. These configurations often become of high importance when you are trying to combine two distinct connections.

It is also true to say that the Multiplexor Protocol is a kernel-mode driver that one can use for Network Interface Bonding. 

In less technical terms, it simply means that two different Ethernet cards are combined to form a single physical device. This is done so that they can increase bandwidth.

When the Network Interface Card (NIC) teaming is initiated, the Microsoft Network Adapter Multiplexor Protocol is enabled for one or two adapters. This often depends upon the connection and also the total number of the network adapters that are connected. However, as that happens, other network adapters can still be using the other items from the list.

Therefore, the Microsoft Network Adapter Multiplexor Protocol should only be put in use when you want to combine two or more adapters. This should be for the typical LAN/WAN connection.

Why is the Microsoft network adapter multiplexor protocol important?

Since the Microsoft Network Adapter Multiplexor Protocol is a kernel device driver, you can use it for Network Interface Card (NIC) bonding.

What NIC teaming

NIC teaming simply refers to the process or act of linking two or more network cards in a certain group. This is done in order to form or create one physical device. This single device that is formed by grouping two or more NICs is to provide for an increase in the network bandwidth or fault tolerance.

We can also say that NIC Teaming is an essence of the protocol. By saying that it is one essence of the protocol I mean; you have to use the Network Adapter Multiplexor to combine two or more adapters only on one computer. Therefore, if your computer has only one adapter then Windows will automatically disable it.

Should you enable the Microsoft network adapter multiplexor protocol ?

This has been the question that many of you have been asking. Should you enable it or not.

As we said earlier, the Multiplexor Protocol comes into play when you are combining Network Adapters or creating a Bridged.

This means that if you try to enable the Multiplexor protocol option manually when the other items in that list are on then you will get an error.

If you enable it and then click on “Yes”, the protocol will remain disabled and the other items will be enabled for your connection.

And if you decide to click on “No”, it will take you back to the list and there will be no changes that will take effect.

Also, it happens that even if you decide to disable all the other options and then try to enable only the “Microsoft Network Adapter Multiplexor Protocol” it still shows this error the above errors.

What does that mean? This means that you can not enable the protocol unless you introduce an into a bridge.

To answer the question that most have been asking, the Microsoft Network Adapter Multiplexer Protocol should therefore not be enabled.

This is because the computer wills automatically enable it when you create a bridge. This protocol does not, in any case, require any manual activation.

There are times when you will need to enable or disable the network adapters; here is how you can achieve that.

Conclusion

I believe that by now your question on whether to enable or disable the Microsoft Network Adapter Multiplexor Protocol has been answered.
