When connecting your computer, smartphone, or any other devices to a local network, each of these devices will receive a unique IP address. The main purpose of using this IP address is to distinguish each device on the same network as well as to communicate with other networks. You can also call this address the internal IP address (IP stands for Internet Protocol).
For example, when you connect a laptop and a smartphone to the same wireless network, each device will have its own unique IP address.
However, sometimes incorrect configuration or wrong IP address settings can cause IP address conflict errors. If you are using a Windows computer, you may see an error message on the screen that looks like: Windows Has Detected An IP Address Conflict.
How to fix Windows Has Detected An IP Address Conflict
Essentially, the error occurs because two devices are using the same IP address on the same local network. As mentioned earlier, each device must have a unique IP address to function properly. Otherwise, the device cannot communicate with other devices, access the Internet, and will be listed as devices unable to connect.
Below, Mytour will guide you through 3 methods to fix Windows Has Detected An IP Address Conflict.
Restart your Modem or Wifi Router
In many cases, a simple restart can help you fix the Windows has detected an IP address conflict error immediately. Here are 2 ways to restart your modem or Wifi Router:
- First, log in to the management page (usually 192.168.0.1, 192.168.1.1, or 192.168.11.1), then access Management =>Reboot.
- The second method is to power off (unplug the power cord or press the power button) your modem or Wifi Router and wait for a few seconds before turning it back on.
After your modem or Wifi Router has finished restarting, try reconnecting to your computer and check if the Windows has detected an IP address conflict error persists.
Reset IP configuration via Command Prompt
If after restarting your modem or Wifi Router the Windows has detected an IP address conflict error still persists, it is likely caused by your computer. Therefore, the solution in this case is to force Windows to request a new IP address from the DHCP server (modem/router). To do this, you will need to reset all IP address configurations as well as release and renew an IP address.
First, press the Windows + X key combination, then press A and select Yes to open Command Prompt with Admin rights.
Next, enter each of the following commands into the Command Prompt window and then press Enter:
netsh int ip reset c:\reset-log.txt
ipconfig /release
ipconfig /renew
After executing the above commands, restart your computer and check if the Windows has detected an IP address conflict error persists.
Manually set a static IP address on your Windows computer
If you have applied the above 2 methods and still cannot fix the Windows has detected an IP address conflict error, you can manually set a static IP address on your Windows computer. To set a static IP address, locate and right-click on the network icon in the bottom right corner of the Taskbar, then select the option Open Network and Sharing Center.
In the Network and Sharing Center window, select the network connection you are using (and also the connection encountering the issue).
Next, select Properties.
Double-click on the option Internet Protocol Version 4 (TCP/IPv4).
The next step is to configure the static IP address according to the information provided by your modem or router.
- IP address: This is the static IP address of your computer that you want to assign, such as 192.168.1.111.
- Subnet mask: The subnet mask is typically 255.255.255.0.
- Default gateway: This is the IP address of the router, which is usually 192.168.1.1.
Note: If the IP address of your modem and router is different, such as 192.168.11.1, the static IP address must also be set according to that address, such as 192.168.11.111. Otherwise, your computer cannot connect to the network.
- Preferred DNS server: 8.8.8.8
- Alternative DNS server: 8.8.4.4
Additionally, you can also use third-party DNS server applications.
Finally, click OK and restart your computer to apply the changes.
In the above guide, Mytour has provided you with 3 methods to fix the Windows has detected an IP address conflict error on Windows computers. Hopefully, these methods can help you resolve the issue.
In addition to the aforementioned issue, another IP-related problem is the IP conflict error, which can severely disrupt internet connectivity. Fortunately, you can easily resolve this IP conflict error following the instructions provided by Mytour.
Furthermore, if you encounter The Another computer has the same IP address error while using the network, you can refer to the solution for The Another computer has the same IP address error here.
