[Fix] “One or More Network Protocols are Missing on This Computer” Error in Windows
Today I'm going to address a very weird and very annoying problem present in Windows 10 operating system. I have faced this problem in 10 of my computer machines which have Windows 10 installed although this problem may also occur in previous Windows versions such as Windows 8/8.1 or Windows 7.
This problem first occurred in an Insider Preview build but I assumed that it was fixed in final RTM build of Windows 10 but I was wrong. The same problem has started occurring again in Windows 10 November Update build 10586 (version 11).
Let's talk about the problem. Suddenly your Wi-Fi or any other Internet connection stops working. Although your computer shows that it has been connected to Internet but no websites open in browser and there is no sign of Internet connectivity. If you try to diagnose the issue by running built-in network troubleshooter by right-click on Network icon in Taskbar notification area (system tray) and select "Troubleshoot problems" option, it throws following error message after running:
One or more network protocols are missing on this computer.
If you try to check the details, you get following reason:
Windows sockets registry entries required for network connectivity are missing.
No extra information is shown and no steps are given to fix the issue and the user has no idea what to do next?
Don't worry! If you are also facing this issue, I'm going to list a few working solutions which will help you in troubleshooting and fixing this irritating issue. I'm going to list the solutions from basic to advanced.
So without wasting time lets start the tutorial:
SOLUTION 1: Disable 3rd Party Firewall or Security Suite
First of all if you are using a 3rd party firewall or Internet security suite (also known as total security suite), then try to temporary disable its protection. If it fixes the connection issue, then its a problem in the security software or firewall and you need to change its settings or replace the security software.
SOLUTION 2: Update Network Adapter Drivers
Sometimes it might be happening due to a faulty, corrupted, outdated or incompatible driver of Network adapters. If you know your computer manufacturer website, go to the website and download the latest and compatible driver for the network adapter and install it. Restart the computer and it may fix the problem.
SOLUTION 3: Uninstall Network Adapters Using Device Manager
If you can't download and install latest drivers for the network adapters, try following:
1. Press WIN+X keys together to launch WIN+X menu and select Device Manager option. Alternatively, you can open it using devmgmt.msc command in RUN or Search box.
2. Now locate the Network adapters section.
3. Right-click on each network adapter one bye one and select Uninstall option.
4. Once all have been removed, right-click again and select Scan for hardware changes option.
The adapters will be rediscovered and Windows will reinstall the drivers. Restart your computer and it may also fix the problem.
