[How to Fix] IP Address Conflict Error on Windows

IP Address is the way in which the network identifies your device. So, it is unique for every device. If your IP Address is already in use within the network, you will see a message on the screen saying Windows has detected an IP Address Conflict.

All private IP Addresses are different. If your IP Address is matching with another device in the network you are using, due to technical difficulties, you will not be able to access the internet. So, you will have to resolve this issue to access the internet

Fixing IP Address Conflict Error

We will detail down some effective solutions, using which you will be able to resolve the issue when the message Windows has detected an IP Address Conflict shows up and you are unable to connect to the internet.

Solution 1: Restart the Router

The router you are using plays the main role while assigning your IP address to the network. Sometimes the router does not give a unique IP address to a device due to some technical difficulties. And that causes the error you are dealing with.

To make sure this is not the case for you, you have to restart your router. Here are the steps to do that.

  • First, turn off your router using the power button on it. You will get disconnected from the internet and your network will shut down.
  • You have to wait for some time. Normally, your router and network take 3-4 minutes to shut down completely.
  • After that turn on your router again.

After the router turns on, check if the error is still there. Maybe you have to connect your device to the internet again.

Solution 2: Enable the Network Adapter After Disabling It

Your device gets interfaced to the network by the network adapter. You can try to fix the IP Address Conflict on Windows by disabling it and then re-enable it. It does not matter if it is a wireless or USB network adapter.

One thing you have to keep in mind is that performing this process requires a local user with administrative privileges.

  • Press the Windows key and the R key together on the keyboard to open the Run utility.
  • Now type the ncpa.cpl and click the OK button. The Network Connection window will open.
  • Then you have to choose the Disable option, after right-clicking on the adapter you are using.
  • Right-click on that adapter again and select the option Enable; after the adapter gets disabled and disconnects you from the internet properly.
  • Now restart the device and try to access the internet to check if the IP Address conflict is fixed.
Solution 3: Release and Renew the IP Address

For any kind of network problem, this is one of the most effective solutions. And when it comes to an IP conflict, you should definitely try this solution. You have to release the current IP using some commands and have to assign a new IP prompting your router.

One thing you have to keep in mind is that to try this fix, you need to have a local user with administrative permissions. 

  • Go to your search bar and search Command Prompt. Select Run as an administrator, after right-clicking on the top result. Maybe you have to put your user password.
  • Now type the three following commands in the command prompt window. Do not forget to press the Enter button after each command.

netsh int ip reset c:\resetlog.txt

ipconfig /release

ipconfig /renew

After completing the procedure, try to access the internet and check if the IP address conflict is still there.

Solution 4: Try Removing the Static IP

If you’ve manually entered and configured the address that your computer is using, you will have a static IP address. This can be the reason behind many kinds of network issues.

Usually, your router assigns an IP address to your device automatically. You should use an automatic IP address instead of the address that you have configured manually when you are facing an IP address conflict.

  • Press the Window key and the R key together on your keyboard to open the Run utility.
  • Once it opens, type ncpa.cpl and hit the OK button. The Network Connection window will open.
  • Choose the option Properties after right-clicking on your adapter.
  • Then double click on the Internet Protocol Version 4 (TCP / IPv4).
  • Choose both Obtain an IP address automatically and Obtain DNS server address automatically that you are going to find in the General tab.
  • Hit the OK button and restart your device.

Solution 5: Try Updating the Card Driver of Your Network

You should update your driver often. Any kind of network issue can occur due to an outdated network card driver.

There are so many methods that you can use while updating your card drivers. Find one that is suitable for your device.

Solution 6: Try Updating the Driver from Windows

You have to use the integrated Device Manager to get an updated driver. Do that following the steps below.

  • Press the Windows key and the R key together to open the Run application.
  • Once it opens, type devmgmt.msc and click the OK button. The Device Manager will open.
  • Click on the arrow icon to expand the Network adapters section.
  • Choose Update driver after right-clicking on the driver.
  • Click on the ‘Search automatically for updated driver software’.
  • The update will be automatically downloaded and installed on your computer by Windows if it can find an updated driver.
  • Now restart your device and try to access the internet to check if the IP address conflict issue is fixed.

Solution 7: Try Disabling IPV6

The IP address conflict that is preventing you from accessing the internet, might be due to the IPv6. Being a new technology, IPv6 can cause this issue if it’s enabled on your system. If the above solutions have failed to fix the IP conflict, try this method to fix it. Here are the steps for disabling IPv6.

  • Press the Windows key and the R key together on your keyboard to open the Run utility.
  • Type ncpa.cpl there and hit the OK button. The Network Connection window will open.
  • Choose the option Properties after right-clicking on your adapter.
  • Then you have to remove the checkmark from Internet Protocol Version 6 (TCP / IPv6) by clicking on the box beside it. The IPv6 on your device will be disabled.
