To get things done easier, we advise you to check your router’s manual. It should contain all the information on how to change password SSID and much more.
4. Changing the number of DHCP users
Some of the users have reported that you can fix a valid IP configuration error by increasing the number of DHCP users. Most of the routers on the market have a maximum of 50 DHCP users, and this can result in the error we are trying to fix. How to increase the number of DHCP users? First, you will need to find your router and then manually increase the number of users. To get this done, it will be convenient to find a router’s manual as these steps can change depending on a router. Many reports that doing this resolves all issues.
Note: You can also try to increase the maximum number of wireless users on your router. Some of the routers are limited to only ten wifi users. Increasing this amount may fix the problem.
5. Setting IP address manually
Every wireless network has its unique IP address. Whenever you connect to a network, the DHCP will give you the current address, but if there are any issues with DHCP configuration, you will get an error. To solve this, you can just assign an IP address by yourself – manually. To do this, follow steps below carefully.
- First, you will have to access Network Connections. The fastest way is pressing Windows Key + X.
- Now just find your wireless network, right-click it and choose Properties.
- Find Internet Protocol Version 4 (TCP/IPv4) and then click Properties.
- In the Properties window choose the option: Use the following IP address. Now you will have to enter IP address, Default Gateway, and Subnet mask. You will have to enter settings that work for your configuration, this may vary from one person to another. You will have to enter DNS server manually. In the image below you can see a Google’s Public DNS, but you can also use 192.168.1.1 as a preferred server.
- After the IP address and server is set, click Ok.
Note: you can also access Wi-Fi router and turn off DHCP. Then configure it to assign a static IP address.
6. Updating or uninstalling wireless adapter driver
There are reports of fixing valid IP configuration issue by updating or uninstalling wireless adapter driver. See steps below.

- If updating driver didn’t help, choose Uninstall device. Click Ok.
- Restart your computer.
When your Windows launches, it will automatically install the default wireless driver. Hopefully, you will be able to access the internet. If the default driver doesn’t work well, you will have to manually install the latest driver. However, this can be time consuming and annoying. To make things easier, we advise getting a Download Windows 10 Drivers tool, that will automatically install everything you need.

- First, you have to open Network Connections(Windows key + X). Then find your Wi-Fi adapter and right-click on it. You will see a list of possible options, choose “Diagnose.”
- Wait for it to finish.
You can also obtain your IP address automatically when DHCP turns on. DHCP can be turned on via Wi-Fi router settings. See 5th solution -Setting IP address manually.
9. Check if security type matches
Security type can also cause issues with IP configuration. Basically, you have to make sure that security type on your PC matches the security type on your router. To manage this just open your router’s setting and under wireless section check what type of security is being used.
10. Removing your antivirus software
Antiviruoftware often interferes with other programs and applications. It can also affect your internet connection. If you get, Wi-Fi doesn’t have valid IP configuration error you should try to remove or disable antivirus or its firewall. A frequently used AVG and Avast antivirus can cause this problem.
