Fix error "WiFi doesn’t have a IP configuration valid" error on Windows 10

If the IP address of the system (Internet Protocol) is incorrectly configured, it will cause an error

All computers and routers are provided with IP addresses to help users access the Internet. Similar to the Wifi Router, the Internet service provider (ISP) provides the IP address for all Wifi Routers to support users to connect to the Internet on their services.

However, in some cases, if the IP address of the system (Internet Protocol) is misconfigured, it will cause an error "WiFi doesn't have a IP configuration valid" or "Ethernet doesn't have a configuration IP validity" or "Wireless network doesn't have a configuration IP hợp lệ".

Usually there are three main causes of the "WiFi doesn’t have a IP configuration valid" error on your Windows 10 computer: a router error, an incorrect IP address error, and finally a NIC error.
