Users of the Windows 10 operating system often come across an error message saying,' WiFi doesn't have a valid IP configuration.' Though frustrating, this is not a severe issue and can be fixed relatively easily. The problem concerns the use of your WiFi network; however, it also may show up if you use Ethernet to connect to the Internet.
'The WiFi doesn't have a valid IP configuration' indicates a problem with the set of network protocol layers (TCP/IP stack), which are not working together properly, resulting in an interruption of the Internet connection. The error message also can appear while you are troubleshooting some other issue, so you may need to fix the problem manually. Other reasons for the 'WiFi doesn't have a valid IP configuration' error message may include incorrect network settings, disabled Windows network services, specific hardware issues, faulty network and others.
To solve the issue manually, there are several things that you can do. First, you can try to release and renew your IP address. Another thing worth trying is to uninstall the driver for your wireless network adapter. Finally, you can reset the TCP/IP protocol and set your IP address manually. Any of these suggestions should work for most Windows users.
