How-to Fix WiFi Doesn’t Have a Valid IP Configuration [Error]

Many users can sometimes see that their WiFi Internet connection doesn’t work. We leave this guide so that you can fix the WiFi error: WiFi doesn’t have a valid IP configuration

Windows 10 has been one of the great innovations developed by Microsoft to gain more users through a friendly, compatible, innovative and secure environment.

The vast majority of users who have switched to Windows 10 have noticed the significant changes that Windows 10 has but, as with most new features, some errors affect the stability and behavior of multiple system elements and one that has suffered this is the subject related to the network.

When the network adapter presents errors, either by WiFi or Ethernet, a large percentage of our daily tasks are affected since today’s world moves by the network.

Today this tutorial will explain some of these problems and give you practical solutions and thus enjoy the most of Windows 10.

You can connect to the Internet?

The first thing you have to check is where is the problem, only on my computer? On my router?

For this, check if you have access to WiFi Internet from another device, whether mobile, tablet or another computer through the same WiFi connection that seems not to work.

Method #1: First-Aid

Although it seems very obvious to you what we are going to suggest you have to recognize it often works, sometimes the most straightforward solution solves the most significant problems.

If you cant navigate from another device, it is the router’s problem; it is best to restart it. If you see that you still don’t have an Internet connection on any device, it is best to call your ISP.

When the other devices can navigate without problems, let’s move on to the next steps to fix the WiFi connection of your computer where it doesn’t work.

PING to a Web

To verify that you don’t have an Internet connection, make a PING to a web from the Command Prompt. Open it as administrator and type the command: ping windowshelper.co

Run TRACERT

There are some connection problems that you can’t see when it falls. For this, we will use TRACERT, a command that tells us the destination route of a series of packages that we are sending. Open Command Prompt as administrator and run the following command: tracert windowshelper.co

Method #2: Update WiFi Driver

In many cases, the errors that Windows 10 generates are because the device drivers are outdated and therefore they are not using all the compatibility parameters with the new operating system.

Although there are third-party tools to update the drivers or drivers in Windows 10, you can use Windows 10 itself for this purpose.

Note: If you have Windows 7 or Vista, I recommend to download Driver Booster because it works great on older Windows versions.
  1. Press the following keys: Winkey + R
  2. Type the command: devmgmt.msc and press Enter
  3. On the Device Manager, find the Network Adapters section.
  4. Find your WiFi Adapter and right-click on it, then select the option Update Driver Software

  5. The following window displays where it will be necessary to choose if you want to search for the update automatically on the network or if you have an update file locally.
    search drivers automatically windows 10
  6. Once finished, restart your computer to apply the changes.

Method #3: Roll Back WiFi Driver

It may sound strange, but sometimes when you updated a network driver the problems are generated instead of being solved, this due to the way the developers have updated the packages and the design of the update. If this is the case do the following process:

  1. Reopen the Device Manager with the command: devmgmt.msc
  2. Right-click on your WiFi Adapter and select the option Properties
  3. Go to the Driver tab, if you have the option Roll Back Driver active, click on it to restore the previous driver

Method #4: Run Troubleshooter

Windows 10 includes a utility called Troubleshoot which allows us, automatically, run an analysis on the feature with failures and, if it has errors, correct them correctly.

  1. Open Windows Settings pressing the keys: Winkey + I
  2. Go to the Update & Security section
  3. On the left click on Troubleshoot
  4. On the right, click on Internet Connections, and then on Run Troubleshooter
  5. Click on Troubleshoot my connection to the Internet and wait for tool to make the several fixes.

Method #5: Reset Commands

Another alternative that you can use in Windows 10 to fix network problems is using the Command Prompt and for this, open the Command Prompt as administrator.

command prompt administrator

Once opened, run the following commands in order:

netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

Method #6: Temporarily Disable your Antivirus

Sometimes installed antivirus or malware protection in Windows 10 can affect Internet connectivity from Windows 10.

To disable the Windows antivirus click on the shield icon located in the taskbar. Now click on Virus & threat protection and then click on Virus & threat protection settings

Now click on the switch under the Real-time protection section to disable Windows Defender Antivirus, then try to connect to the WiFi again.

For others Antivirus software, you can right-click on the icon in the taskbar and look for some option like temporary disable or shield disable:

avast disable antivirus

Method #7: Temporarily Disable Firewall

Windows 10 firewall helps us protect the computer from unwanted connections and thus maintain a stable level of security, but sometimes the Windows 10 firewall can cause Internet connection, so you can turn it off temporarily to check if there lies the problem. You can disable the Windows 10 firewall using two methods:

Option #1: Control Panel

  1. Open the Control Panel
  2. Click on System and Security, then on Windows Defender Firewall
  3. On the left panel, click on Turn Windows Defender on or off
  4. Now check the boxes Turn off Windows Defender Firewall
  5. Now, check if the error: WiFi doesn’t have a valid IP configuration is fixed.

Option #2: Command Prompt

The second method to disable Windows 10 firewall is to use the Command Prompt as administrators and run the following command: netsh advfirewall set allprofiles state off

This will disable all firewalls in Windows 10.

Method #8: Reset Network Settings

Windows 10 includes within its configuration options the possibility of resetting the network settings to the default.

  1. Open the Windows Settings pressing the keys: Winkey + I
  2. Go to the Network & Internet section
  3. On the left click on Status
  4. Move to the bottom and click on Network Reset

  5. Finally click on Reset Now to reset all your network settings, then check if the error it’s fixed.

Method #9: Change DNS Servers

DNS allows the system to convert IP addresses into domain names.

The problem is that sometimes our default DNS, the one provided by the ISP has failures, and therefore there is no exit to the network, and unfolds the message WiFi doesn’t have a valid IP configuration which affects our navigation.

To fix this you can make use of public DNS servers, such as Google’s DNS, to have a stable and secure DNS server.

To change the DNS servers, open the Control Panel and navigate to Network and Internet > Network and Sharing Center

On the left, click on Change adapter settings, then right-click on your Wi-Fi adapter and select Properties

Double click on Internet Protocol Version 4 (TCP/IPv4)In the window that opens, check the option Use the following DNS server addresses.

Now, type the following Google Public DNS Servers:

Preferred DNS server: 8.8.8.8

Alternative DNS server: 8.8.4.4

Click OK, and check if your WiFi problem has been fixed correctly.

Method #10: Disable and Enable Network Adapter

This is another of the alternatives that you do run in Windows to fix wifi errors; it consists in disabling the adapter and then enabling it to refresh its settings.

For this we will use the Command Prompt, so open it as administrator and run the following commands in order:

netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set global rss=enabled
netsh int tcp show global

Finally, restart your computer to apply the changes.

Method #11: Remove VPN Connections

In some cases, the connectivity failures in Windows 10 are due to the fact that you have VPN services which affect the normal connectivity of the WiFi network or LAN in Windows 10.

To disable these services run the following command in the Command Prompt as administrator

reg delete HKCR\CLSID\{988248f3-a1ad-49bf-9170-676cbbc36ba3} /va /f

Then run the following command:

netcfg -v -u dni_dne

As you can see, there are several alternatives to fix the error: WiFi doesn’t have a valid IP configuration. Many of these methods can be performed in Windows 7 and 8 without problem.

If for any reason you have any network problem or any other type in your Windows 10, remember that you can ask for help in the comments, I will help you quickly as I can.
