What to do when one or more network protocols are missing

The information below has been carefully chosen and gathered to help users who have experienced the “You are missing one or more network on this computer” error find a solution to this problem. The Guides attached below are compatible with all Windows versions.

This kind of error occurs because of some Windows Sockets registry entries, required for network connectivity. Sometimes some of the entries are “missing”  and that causes the aforementioned  error. The problem gets reported by Windows Network Diagnostics. Usually such an error occurs when your PC is unable to connect to the internet and you decide to run a Diagnose Check. Maybe you will be capable of pinging your destination address, however, your browser will be incapable of doing the same. Most commonly, some kind of inconsistency in Windows Sockets API also known as Winsock is the reason for this issue. This socket is the component, responsible for both the incoming and the outgoing network requests of the programs. Such a problem might also occur because of your Internet Provider. Nevertheless, in case the Internet works well on of any of your other devices connected to the same ISP, it means that the ISP is FULLY FUNCTIONAL. After concluding this, we can go on with the troubleshooting options.

Solution #1: Stop IPv6

Firstly, you have to click on the Start Button. Secondly, you have to enter regedit and push the Enter key. After that, review SYSTEM, CurrentControlSet, HKEY_LOCAL_MACHINE, TCPIP6, services, and Parameters. Then just right-click on Parameters and choose New. Then select DWORD (32-bit) Value. Give a new name to the value – DisabledComponents,  and then press Enter. Then again right-click on the newly-set DisabledComponents value and hit Modify. Change the value of DisabledComponents to FFFFFFFF. Press OK. IPv6 should be completely disabled after the system performs a restart.

Solution #2: Restart Winsock

If your Winsock is corrupted, it is likely to cause such errors. Normally, the problem could be solved by rebooting winsock. In order to do that, stick to the instructions below.

Hit the Windows key. Enter cmd in the search box. You will see a list of  results displayed, simply choose cmd and select Run as Administrator. If your OS is Windows 8 or 10, press the Windows Key, hold it and press X. Select Command Prompt (Admin).

A black command prompt window will appear. There, write “netsh winsock reset.  After that press Enter.

Reboot your PC and check whether your problem has been solved.

Solution #3: Reboot Your Network Adapters

An occasional bug in network adapters might stop it from picking up the necessary protocols. Sometimes all you need to do is to perform a simple restart of the adapters. Do that by holding the Windows Key and pressing R. You will see a dialog – enter ncpa.cpl  there. After that select OK.

There will be a list of network adapters. In case you are not sure which one exactly is the one you need, implement the instructions below for all of the listed adapters.

Just right-click on the chosen Network Adapter, and press Disable. After that right-click on it once more and select Enable.

Solution #4: Restart Components

This potential option involves resetting and refreshing components participating in network connectivity.

Create a text file and paste the following code in it, after which save it as fixnetwork.bat

ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew
NETSH winsock reset catalog
NETSH int ipv4 reset reset.log
NETSH int ipv6 reset reset.log

What you need to do is to rightclick on the newly-created bat file and select Run as Administrator. Be careful with the “access denied messages. In case you see any, simply go on with the following instructions below. Press any key when you are asked to restart the system. Then, simply TEST it.

Attention! It is recommended to back-up your registry before doing anything that involves it. To do that you need to click on File ->Export (with Computer) chosen from the top-left pane; and export it (saving it somewhere on your  PC).

Solution #9: Modify the Wireless Mode of your internet router’s to 802.11g

Some users have managed to fix this error by changing their wireless router’s Wireless Mode from 802.11b+g+n to 802.11g. Typically, nearly all wireless routers are in the 802.11b+g+nWireless Mode out of the box. For the purpose of altering your internet router’s Wireless Mode to 802.11g, you have to:

Access your wireless router’s administration and settings panel via a browser of your own choice. Instructions for logging in your wireless router’s administration and settings panel are usually available on the user manual that comes with your wireless router. Review everything under the Wireless category. Look for a setting called Wireless Mode or Mode. Modify  your wireless router’s Mode/Wireless Mode to 11g or 11g – whichever is applicable in your case. Save the changes you have made and exit the administration and settings panel of your Wireless Router. Reboot both your   router and your device. Once your PC gets restarted, check whether the error has disappeared.

Solution #10: Maybe performing a hard-reset of your wireless router will help

Provided that the options above are not helpful in your case, there is one more thing you can try. What you need to do is to implement a hard-reset of the router you use. What a hard reset of your router normally does is recover all of its default settings and preferences. In 90% of the recorded case, by doing that, you will be able to fix your problem and regain your Internet access. If you want to perform such a reset, you have to:

  Take a paperclip or a pin (or any other pointy object).

Find the recessed Reset button of the router. Normally, this button represents a small hole. Usually it is located at the back of your router with the word Reset put above or below it. Insert the pointy end of whatever you are using into the Reset button. Push it all the way in and hold it inside for some time. This should complete a reset of your router successfully.
