Release And Renew Your IP Address
This might be the easiest way to fix the
"WiFi doesn't have a valid IP configuration" problem by executing commands in Command Prompt. First, open Command Prompt by typing
"command prompt" in Search and right-clicking on the
"Command Prompt". Then, select
"Run as administrator" to run it with administrator privileges.
In the Command Prompt window, type
"ipconfig /release" and press Enter on your keyboard. Make sure that you put a space between
"ipconfig" and "/release" in the command.
Now, do the same with the
"ipconfig /renew" command. You must put a space after
"ipcongif" in this command as well. Press Enter.
When you have finished entering the commands, type
"exit", and press Enter to exit Command Prompt. Try restarting your computer to see if this helped to solve your problem.
Reset TCP/IP
This one is also simple: execute commands in Command Prompt. Open Command Prompt from Search again by right-clicking on it and run as administrator. In the Command Prompt window, type the
"netsh winsock reset" command and press Enter on your keyboard.
Then, type the
"netsh int ip reset" command and press Enter on your keyboard. Exit Command Prompt and restart your computer to see if it helped to solve the problem.
