- A common network error in Windows is the “Wifi does not have a valid IP configuration” error message.
- This is one of the few Windows network errors for which there is no automatic solution.
- The problem can be caused by a faulty network, improper network settings, hardware issues, problems with your carrier’s network, disabling Windows network services, etc.
- If you still get the error, you need to uninstall and reinstall the wireless network adapter on your computer.
Wifi Doesn’t Have A Valid Ip Configuration
When your Wifi Network Adapter reports an incorrect IP address, this error is reported by the Router. During an update to Windows or after network changes have taken place that have not yet been pushed to the Network Adapter, it may also occur if the driver, router, or DNS is malfunctioning.
What Is An Ip Configuration
In order for a computer to connect to the Internet or another computer, it needs an IP address. This address is assigned dynamically or statically based on the type of network adapter used.
A “Wifi does not have a valid IP configuration” error message is one of the worst things about using devices with Wi-Fi.
The no WiFi problem after installing Windows 10 Fall Creators Update or Creators Update/Anniversary Update is caused by WiFi not having a valid IP configuration. When Windows users attempted to diagnose a wireless failure, they received an error message stating that there was no valid IP configuration.
There is an error message in Windows that says “Wifi does not have an IP configuration that is valid.” Unless there is an automatic solution to this error when it is reported by a network diagnostic tool, you will need to find a solution on your own.
Wifi Does Not Have An Ip Address
If a computer is unable to configure a valid Internet Protocol address, it can’t connect to a network. If you plug a laptop directly into a modem with an Ethernet cable and receive a “No Valid IP Address” error, there could be a problem with the hardware setup or the Internet Service Provider. Laptops are more likely to connect to multiple networks than desktops because they are easier to transport. If accessing one network requires special settings, those settings may affect the laptop’s ability to connect to other networks.
After bouncing your router, restart your PC and see if you can regain solid Wi-Fi connection by unplugging it for 30 seconds and plugging it back in.
In the following paragraphs, you will find explanations of the most common causes of this error and solutions to it.
