If restarting your computer didn’t fix the problem (try that if you haven’t already), then the troubleshooting tips that follow should help you sort things out.
Restart Your Router
Restart Your Router
In most cases, the “Wi-Fi doesn’t have a valid IP configuration” error shows up due to random faults on the router side. The solution—restart your router. Start by turning OFF the router. Then, wait for at least 10 seconds before turning it back ON. Once your computer re-establishes its connection to Wi-Fi, check if you can access the internet without issues.
Reset Wireless Network Adapter

Disabling, and then re-enabling your PC’s wireless network adapter is another potent fix for connectivity-related issues in Windows 10.
Renew Your PC’s IP Lease
Renew Your PC’s IP Lease
If restarting the router or disabling/re-enabling the wireless network adapter didn’t resolve the issue, you should force your computer into renewing the IP lease. You can do that by running several commands via Windows PowerShell.
ipconfig /releaseipconfig /flushdns (optional)ipconfig /renew
Reset the TCP/IP Stack
Reset the TCP/IP Stack
If renewing the IP lease didn’t help, you should reset your PC’s TCP/IP stack. That requires running a couple of commands again but via an elevated Windows PowerShell console this time.
netsh winsock reset catalognetsh int ip reset
Reinstall the Wireless Network Adapter
Reinstall the Wireless Network Adapter
If you still keep receiving the “Wi-Fi doesn’t have a valid IP configuration” error message, you must uninstall and reinstall the wireless network adapter on your computer. That should rule out a corrupted driver from the equation.
Update the Wireless Network Adapter
Update the Wireless Network Adapter
If disabling and reinstalling the wireless network adapter didn’t help, you must update its driver. Windows 10 installs a generic driver by default, but it’s a good idea to grab an up-to-date copy from the device manufacturer’s website. You must—obviously—use a device with an active internet connection for that. Once you’ve downloaded and transferred the driver setup file, just run it and follow all on screen instructions to update the wireless network adapter.
Obtain the IP Address Automatically
Obtain the IP Address Automatically
Have you configured your PC’s wireless network adapter with a custom IP address and DNS settings? If so, you should switch back to obtaining them automatically.
Change the Router’s SSID and Password

Another way to fix the “Wi-Fi doesn’t have a valid IP configuration” error is to change the SSID and password of your router. To do that, you must visit the router’s settings. Note: You need the router’s gateway IP, username, and password to gain access to its settings. You can typically find the details on a label somewhere on the router itself.
Run the Network Adapter Troubleshooter

Now that you’ve already worked your way through a substantial number of fixes, it’s time to diagnose your Wi-Fi connection once more using Windows 10’s network troubleshooter.
Reset Your PC’s Network Settings
Reset Your PC’s Network Settings
It’s time to reset your PC’s network settings. That should revert every network-related setting to its default and likely patch out incorrect or corrupt configurations for good.

You can usually resolve the “Wi-Fi doesn’t have a valid IP configuration” error by restarting the router, resetting the wireless network adapter, or renewing the IP lease.
