The “Wi-Fi doesn’t have a valid IP configuration” error message can be frustrating, but it’s usually caused by a temporary glitch that can be fixed with a few simple steps. Here are four methods you can try:
1. Restart your router. This is the easiest and most common fix for this error. A simple restart can clear up any temporary issues that may be causing the problem. To restart your router, unplug it from the power outlet for about 30 seconds, then plug it back in and wait for it to power on completely.

3. Reset your network adapter. This will reset your network adapter to its default settings, which may fix the problem. Here’s how to reset your network adapter on Windows:

Click on Network adapters.
Right-click on your network adapter and select Disable.

4. Change your DNS server. Your DNS server is responsible for translating domain names into IP addresses. If your current DNS server is having problems, you can change it to a public DNS server like Google DNS or OpenDNS. Here’s how to change your DNS server on Windows:

Open the Start menu and type Control Panel.
Click on Network and Sharing Center.

Right-click on your network adapter and select Properties.
Click on Internet Protocol Version 4 (TCP/IPv4) and then click Properties.
Select Use the following DNS server addresses.
Enter the following DNS server addresses:
Preferred DNS server: 8.8.8.8
Alternate DNS server: 8.8.4.4
Click OK to save your changes.
If none of these methods work, you may need to contact your internet service provider (ISP) for further assistance.
Here are some additional tips:
Make sure that your router’s firmware is up to date.
Check for any physical damage to your router or network cables.
Try connecting to a different Wi-Fi network.
If you are using a VPN, try disabling it.
