Occasionally, you get the error message under Windows 10 “Ethernet does not have any valid IP configuration”. If restarting the PC and router does not help, open the “Run” window and type “regedit”.
In the registry, navigate to the folder “Parameters” via “HKEY_LOCAL_MACHINE| SYSTEM| CurrentControlSet Services | TCPIP”.
Here, you can create a new “DWORD value (32 Bit)” via the context command “New” after a right-click on it. Type the name “IPAutoconfigurationEnable” for the entry and enter the value “0” after double-clicking on it in the “Edit” window.
After restarting the computer, the LAN or Internet connection should start working properly again.
