One or More Network Protocols Are Missing – Every Possible Fix

Posted by Heather on June 22, 2016

If you’re a Windows user, you may have come across this common error: “One or more network protocols are missing.”  In an instance when you’ve faced a problem connecting to the Internet and chose to click on the “diagnose” button, the Windows network diagnostics tool may have displayed this message to you. What does it mean, and how do you fix it?

As long as the Internet is working on all of your other Internet-connected devices, it’s most likely the computer you’re using that is having the issue—not your Internet provider causing your woes.

Restart Your Network Adapter(s)

The first and easiest thing to try is disabling and re-enabling your network adapter. It could just be a hiccup your network adapter is experiencing.

  1. Hold down the Windows key and the “R” key on your keyboard.
  2. Type “ncpa.pl” in the “Run” box that pops up on your screen. Then, click the OK button.                                                     ncpa
  3. Right-click on your network adapter and choose “Disable.”                                                                                                       Adapter
  4. Right-click on your network adapter once again, and now select “Enable.”

Now, check to see if the problem is resolved and you’ve successfully connected. Yes? Great! You’re done.

No? Okay. Onward.

Disable Proxy

Have you enabled specific proxy settings? You may have done this to share an Internet connection on your local area network (LAN), hide your IP address, or to gain access to blocked websites and so forth. Try turning “set proxy settings” off and use automatic proxy settings.

  • Click the Windows icon in the taskbar, and select “Settings” from the list.                                                                                                                          Windows Start settings
  • Click on “Network & Internet” in Settings.                                                            Internet
  • Go to “Proxy” at the bottom of the list and select it. Where it says “Manual proxy setup,” toggle the button to the “Off” position.                                                                              Proxy Auto setting

See if allowing automatic proxy settings has resolved your connection issue. Not fixed yet? Keep reading.

Disable IPV6

Dig a little deeper and try disabling IPV6.

  1. Hold down the Windows key and press the “R” key on your keyboard.
  2. Type “ncpa.pl” in the “Run” box that pops up on your screen. Then, click the OK button.                                                     ncpa
  3. Right-click on your network adapter on the next screen and select “Properties.”                                                                  wifi properties
  4. Uncheck the box near “Internet protocol IPv6 (TCP/IPV6)” and click the OK button.                                                                            IPV6

This disables IPV6 for the selected adapter. For other adapters attached to the same computer, you must do this individually for each one. Still no resolution? Let’s try the next thing on our list.

Winsock Reset

Winsock can become corrupt, causing the “one or more network protocols are missing” error to happen in Windows as well. In Windows 8 and 10, follow the steps below.

  1. Press the Windows key and the “X” key on your keyboard.
  2. In the menu that appears on your screen, select “Command Prompt (Admin).”                                                                                                                 cmd admin
  3. The command line window will open and you’ll type “netsh winsock reset” and hit the “Enter” key on your keyboard.         Windows socket reset
  4. You’re going to see “Successfully reset the Winsock Catalog.” You must restart the computer to complete the reset.  Windows socket success
  5. Reboot your computer. See if the problem has resolved. Once you’ve restarted your computer, hopefully the issue has resolved itself.

The last suggestion involves your wireless router.

Wireless Router Reboot

Now and then, you may need to restart your wireless router. Sometimes this simple solution is just what you needed, and you’ll be kicking yourself that it really was that easy.

  • To reset your wireless router, disconnect the power cord from the back of the wireless router or from the AC adapter in your wall, where it’s plugged in. Wait for a good two to three minutes and plug it back in.

This has been known to resolve latency problems and just give everything a fresh start, so to speak.

One of these solutions is bound to fix the “one or more network protocols is missing” error. Have you found another solution that’s not listed? Let us know!
