When connecting your computer, smartphone, or any device to a LAN, each device is assigned a unique IP address.
The primary purpose of this is to provide devices with an IP address when joining the network, facilitating accurate information exchange between devices without loss.
Understanding IP Addresses: The Key to Device Differentiation
For instance, when connecting a computer, laptop, and smartphone to the same wireless network, each device will have its own unique IP address.
However, in some cases, the IP address may be configured incorrectly or due to some malfunction. IP conflict errors can occur. If you are using a Windows computer, you will see a notification on the screen indicating the occurrence of this error.
How to Resolve IP Conflict on Computer
In simple terms, an IP conflict on a computer occurs when two devices are using the same IP address on the same internal network. As mentioned earlier, each device must have a unique IP address to function normally.
Without this, the device won't be able to communicate with other devices, nor can it access the Internet, rendering it as a disconnected device.
Here are some solutions to fix IP conflicts on a computer:
Solution 1: Restart the Modem or Wireless Router
In many instances, a simple reboot can help you fix an IP address conflict on your computer. You have two options: restart the modem or restart the Wireless Router:
- Log in to the administrator management page (usually 192.168.0.1, 192.168.1.1, or 192.168.11.1) and then access Management => Reboot.
- Turn off the router (use the Power button or unplug the Router power cord) and wait for a few seconds, then turn it back on.
After restarting the modem and wireless router, try connecting your computer to the network and check if the issue persists. If you are using a TP-Link wifi modem, refer to the method of resetting TP-Link wifi modem for implementation.
Solution 2: Resetting IP Configuration via Command Prompt
If after restarting the modem or router the issue persists, it might be a computer-related problem. Try forcing your Windows computer to request a new IP address from the DHCP server (modem/router). To do this, you can reset the entire IP configuration, including releasing and renewing the IP address.
First, press Windows + X, then press key A, and choose Yes to open the Command Prompt with Admin rights.
Enter the following commands in the Command Prompt window:
Execute the command netsh int ip reset c:\reset-log.txt
Execute the command ipconfig /release
Execute the command ipconfig /renew
After executing these commands, restart your computer and check if the issue still persists.
Solution 3: Manually Set Static IP Address for Windows Computer
If you've tried the previous two methods and still haven't resolved the IP address conflict, you can attempt manually setting a static IP address on your Windows computer.
To do this, find and right-click on the network icon located in the bottom right corner of the Taskbar, then choose Open Network and Sharing Center.
In the Network and Sharing Center window that appears, select the network connection you are using (which is also the one experiencing issues).
Right-click on it and select Properties.
Double-click on the option named Internet Protocol Version 4 (TCP/IPv4).
In the next window, configure the static IP address based on the details provided by the modem or router:
- IP address: This is the static IP address you want to assign to your computer. For example: 192.168.1.111.
- Subnet mask: The subnet mask is typically 255.255.255.0.
- Default gateway: This is the router's address, usually 192.168.1.1.
Note: If your modem/router's IP address is different, such as 192.168.11.1, there are various ways to check the IP address on your computer. In that case, your static IP address should be set accordingly, for example, 192.168.11.111. If you don't verify the correct IP address and input the wrong format, your Windows computer won't be able to connect to the network.
Preferred DNS server: 8.8.8.8
Alternative DNS server: 8.8.4.4
You can also utilize third-party DNS server applications like Google Public DNS Server, OpenDNS, Norton ConnectSafe, and more.
After entering all the necessary information, click OK and restart your computer.
Hopefully, these methods can help you resolve IP address conflicts on your Windows computer. If you have any questions or concerns, feel free to leave a comment below.
