How To Fix “Windows Has Detected An IP Address Conflict”

Cover Image of Windows Has Detected An IP Address Conflict

Are you getting this network error “Windows has detected an IP address conflict in your PC?

Well, this type of error mostly occurs when another device on the same network has the same IP address as your computer.

Even sometimes when there is only one device connected to the network the error can still occur. Let me explain it further to better help you understand this network error.

When you connect your devices to a local network it will give every device a unique IP Address. The devices can be anything (Mobile, Computer, Tablet).

The main purpose of this unique IP address is to provide a clear path with the network and its elements.

It also provides a clear path to easily distinguish each device on the same network and helps to communicate between devices. So, whenever you connect any kind of device to the same network wirelessly this will generate a unique IP address to each of the device connected to it.

However, sometimes the things don’t work the way they were designed to perform and this will make the wrong configuration errors to pop up on your screen. Before getting into the solutions let me explain you a quick tip which will save you time.

“This type of error mostly occurs between your PC settings or Router and thus it doesn’t have to do with your Internet services provider. It’s a type of glitch between your computer settings or router settings”

Got the tip?

Let’s go further now and see the possible solutions that can help in solving this error.

How To Fix Windows Has Detected An IP Address Conflict

Method 1- Restart Your Router/Modem.

Try to restart your router first before going through other methods because sometimes there is a possibility that the router might fail to get the unique IP address to the computer.

Sometimes it can also happen when we use any VPN to hide our IP address because the purpose of VPN is to change our IP address so we can access the web with more protection but as I told you the things may not work sometimes the way they were designed to.

Here is how to restart your router

  1. Look for the power button of your router.
  2. Once you find it, press the power button and set it to “OFF” and wait for around 15-20 seconds.
  3. Also, check that no VPN connected while doing all this.
  4. It will be super cool if you restart the computer as well.
  5. Now, press the power button again to turn it to “ON”.
  6. Check if it solves the issue or not.

Method 2- Release And Renew Your IP Address

If the above solution didn’t work then, its probably because of your computer’s internal error. So, let’s force the computer to ask the DHCP server (router/modem) for a new IP address.

  1. Press the Windows key to open the “Start Menu” and find the “Windows System” folder from the list.
  2. Click on it and open the “Command Prompt” as Admin.
  3. Now on the black window type this command “ipconfig/release” and press Enter. This will start the configuration.
  4. Now type “ipconfig/renew” again and press the enter button to get it started.
  5. Wait for the configuration process to complete and close the command prompt.
  6. Browse the internet to check if it’s working properly or not.

Method 3- Remove Your Static IP Address

  1. On your keyboard, press the “Windows + R” key and open the run box.
  2. Now, type “ncpa.cpl” in the run and hit the enter button to open the Network Connections screen.Image of Find network settings using ncpa.cpl command
  3. Right-click on your Network connection and choose the Properties option to open it further.
  4. From there Double-click on the “Internet Protocol Version 4(TCP/IPv4)” to open the properties.
  5. Now click on both “Obtain an IP address automatically” and “Obtain DNS server address automatically”. Click “OK” and close all the windows.Showing how to change DNS setting in Windows 10
  6. Restart your computer now to see if the “Windows has detected an IP address conflict” error has been solved or not.

The current manually static IP address may be causing the error thus that’s why by doing the above method we can easily set the options to Obtain the IP address automatically.

Method 4- Disable IPv6

By disabling the IPv6 protocol the error can be solved because generally it is not used widely by many users. Many users reported that disabling this feature really helps them.

So, let’s see how you can disable it and fix the network error.

  1. Open the “Run” command by pressing the “Windows + R” key on your keyboard.
  2. Type the “ncpa.cpl” and hit the OK button to get it started.
  3. It will open the “Network Connections” window. Now locate to the network adapter and right-click on it. Select the Properties and let it open.Showing how to Disable the IPV6 In windows 10
  4. In the “Properties” uncheck the “Internet Protocol Version 6 (TCP/IPv6)” option and click OK.
  5. Now you have disabled the IPv6 option completely. Check if it solves the “Windows has detected an IP address conflict” error or not.

Method 5- Update Your Network Drivers

If your network drivers are outdated this error may also be caused due to it. You can update your network drivers manually by using the below steps.

  1. Press “Windows + R” keys to open the “Run” screen now type “devmgmt.msc” and tap OK to open the Device manager.
  2. In the device manager locate to “Network adapters” and click on the arrow to expand it.
  3. Click on the listed adapters that are installed in your PC. Right-click on them one by one and click “Update driver”. Now Update them automatically one by one and wait for the process to complete an update.Showing how to update network adapters
  4. If you are not sure on how to play around with all this stuff manually then you can also use the software like “Driver Easy” which will automatically update the required drivers without any worries.

Method 6- Disable Then Enable Your Network Adapter

Sometimes simply disabling and then enabling the network adapter can solve the whole error in no time & here’s how to do it.

  1. Open the run command by pressing the “Windows Key + R” together.
  2. Type the “ncpa.cpl” and press the OK button to open the Network settings.
  3. Locate to your network adapter and Right-click on it to disable it. By disabling, it will stop the network adapter on your PC. Again Right-click on it and Enable it to see if it helps to solve this problem or not.

This method will restart the whole network adapter.

Method 7- Restart Your PC

Restarting your PC can solve the problem immediately. It is the easiest possible fix of this error. All you have to do is turn off your computer and start it again. Usually that fix the problem automatically.

Method 8- Change Your Router Encryption

Another simple and useful solution that you can try is by changing the encryption type of your router. To do this you have to open the configuration page by logging into your router’s IP address.

Here’s how to find your router’s IP address.

  1. Click on Start, now type CMD in the search box, and then select Command Prompt as Admin.
  2. When a new window opens, type “ipconfig” and hit enter.Showing how to Check your IP from CMD prompt using ipconfig
  3. You will see the IP address next to Default Gateway (in the example below, the IP address is:

From there you will have to find the Wireless section and see the encryption field available.

Change the encryption from WEP to WPA2-PSK [AES] and see what happened after it. You can also try other encryption methods also until you find the one which helps you to get rid of this problem.

Just be sure you select the best encryption method because not all encryption methods are secure. I hope so, your problem is solved until now by using the above methods.
