[FIXED] One or More Network Protocols are Missing Error

[FIXED] One or More Network Protocols are Missing Error

/ Shayne Sherman

You may run across one or more network protocols missing on this computer error when you attempt to get on the Internet or may have even been online, and suddenly pages stop opening.

You probably already ran the built-in Windows Network Troubleshooter, and this error appeared. Trying to determine this error’s cause and fix it can be very frustrating, especially without an Internet connection.

However, there are several methods of resolving the issue below.

What Causes the One or More Network Protocols Are Missing Error?

Usually, you see this error when Windows Socket entries are missing. In some cases, this can occur after an update.

Since these entries are necessary registry entries that enable your computer to connect to the Internet, the error appears. If more than one device struggles to connect to the same ISP, the problem probably stems from your Internet Provider.

If you are only having trouble connecting one device and have not already run the Windows 10 Network Troubleshooter on that device, you should run it to confirm missing protocols are the cause.

Fix #1: Run the Windows 10 Troubleshooter

If you already did this, feel free to skip solving the error. It should be your first step to resolving Internet connection issues if you have not run the Troubleshooter.

search troubleshoot

Step #1

Type “Troubleshoot” into the Start menu without the quotation marks and choose “Troubleshoot System Settings.”

Step #2

Click “Internet Connections” and then choose “Run the Troubleshooter.”

run internet connections troubleshooter

When the Troubleshooter finishes, see if you get the missing protocols message. If you do, continue reading to resolve it.

Fix #2: Restart the Router

This is the simplest and least invasive way to fix the issue. However, it will only work if the router itself is causing the error.

Step #1

Shut down your computer by clicking the Power icon on the Start menu and holding the [Shift] key while selecting “Shut down.” Then shut off your router.

shutdown pc

Step #2

Unplug your router and wait two minutes before plugging it back into the power outlet. Wait another two minutes after plugging the router back into the power outlet. Turn the router on again.

Step #3

Once your router is back on, turn on your computer.

If the issue is resolved but happens again multiple times in the future and resetting the router temporarily fixes it, you should consider getting a new one.

If you use a Powerline network, you need to look at the owner’s manual that came with it and follow the instructions to reset it when you unplug your router in Step #2 above.

Fix #3: Make Sure Windows Is Up-to-date

Another quick way to deal with this issue is to ensure your Windows 10 OS (operating system) is up-to-date. Although a faulty update can cause the problem, in some cases, the update fails to load correctly.

In other cases, Microsoft has issued a fix, but your connectivity issues may play a role in the continuing error. To update Windows 10 manually, follow the steps below:

Step #1

Click on the “Settings” icon in the Start Menu.

windows settings

Step #2

In the Settings window, choose “Updates & Security.”

Continue if you are still not connected.

Fix #4: Disable Bluetooth

Your Bluetooth feature sometimes is set to use the same band as the WiFi. If both are active, it can cause a conflict that leads to this error message.

Step #1

Click on the Start menu “Settings” icon.

Check to see if you can connect to the Internet. If you are still having problems, continue reading.

Fix #10: Uninstall a Third-Party Antivirus

If you are using a third-party antivirus, the antivirus may be interfering with some components of Windows—including the protocols. Since Windows 10 comes with Windows Defender, first make sure Windows Defender is deactivated if you are running a third-party antivirus.

Running two antivirus programs simultaneously can cause problems because the programs interfere. To find out how to deactivate Windows Defender, click here.

Since each antivirus is different, the instructions below are general and not specific to any antivirus program.

Step #1

After you disable Windows Defender, you need to uninstall your antivirus software if you still see the Critical Error message. Press the [X] and [Windows] keys simultaneously. Choose “Settings” from the list.

Frequently Asked Questions

How do I fix my network protocols are missing?

If you are experiencing issues with your network protocols, there are a few steps you can take to try and resolve the issue. First, check to see if your network drivers are up to date. If they are not, you can try updating them and see if that resolves the issue. If that does not work, you may need to uninstall and reinstall your network drivers. Finally, if all else fails, you can try resetting your network settings to their defaults.

What does this mean “windows sockets registry entries required for network connectivity are missing?

Windows sockets are low-level software that enables the communication between your computer and the internet. When you try to connect to the internet, Windows looks for settings in the registry that tell it how to connect. If the necessary entries are missing, you won’t be able to connect.

How do you run windows network diagnostics?

The Windows Network Diagnostics tool can diagnose and fix networking problems on a Windows computer. To use the tool, open the Control Panel and go to Network and Sharing Center. Click the link for your network connection, then click the Diagnose button. The tool will run a series of tests and attempt to fix any problems it finds.

What to do when one or more network protocols are missing?

If you are missing one or more network protocols, the best course of action is to consult with your network administrator. They will be able to advise you on which protocols are required for your particular network and how to go about implementing them. In some cases, it may be possible to download the necessary protocols from the internet; however, this is not always the case. Once you have implemented the required protocols, you should be able to connect to your network without any issues.

How to troubleshoot network connectivity problems?

There are a few different ways that you can go about troubleshooting network connectivity problems. The first thing you need to do is identify the source of the problem. Is it on the client side or the server side? Once you’ve identified the source, you must check the log files for error messages. This will help you narrow down the problem and find a solution. You can try restarting the computer or changing the DNS settings if the problem is on the client side.
