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
- Open the Command Prompt (Admin) or PowerShell (Admin).
- Execute netsh winsock reset
- Execute netsh int ip reset
- Execute ipconfig /renew
- Execute ipconfig /flushdns
- Execute netcfg –d
- Restart the computer.
[Solution 2] Update or reinstall the network adapter driver
- Open Device Manager.
- Expand the tab Network Adapters.
- Right click a driver which internet connection isn't functioning and select Update drivers.
- Choose Look on my computer for another driver, do not choose update automatically.
- Then, choose to I want to choose from a list of drivers on my computer on the computer.
- A list of available drivers will now be displayed. Double-click any of the drivers in this list but not the first one.
- 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.
- 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.
