Windows: network protocols missing

Software: Windows 7, 8 & 10 | Last modified on 2018-06-19

Windows refuses to establish a connection using a wireless connection and informs you that the Network Protocols are missing. This error indicates that a registry key is corrupt and has to be reset.

[Solution 1] Reset the network protocols

  1. Open the Command Prompt (Admin) or PowerShell (Admin).
  2. Execute netsh winsock reset
  3. Execute netsh int ip reset
  4. Execute ipconfig /renew
  5. Execute ipconfig /flushdns
  6. Execute netcfg –d
  7. Restart the computer.

[Solution 2] Update or reinstall the network adapter driver

  1. Open Device Manager.
  2. Expand the tab Network Adapters.
  3. Right click a driver which internet connection isn't functioning and select Update drivers.
  4. Choose Look on my computer for another driver, do not choose update automatically.
  5. Then, choose to I want to choose from a list of drivers on my computer on the computer.
  6. A list of available drivers will now be displayed. Double-click any of the drivers in this list but not the first one.
  7. Another driver is now installed for the network adapter. Repeat these steps again but now choose the first driver in the list. There is a chance the internet connection might now work again.
  8. If these steps failed, try to experiment with changing the network drivers locally, else you should perform an In-Place Upgrade to repair the registry.
