Error of IP conflict on the computer is not uncommon, with large computer networks with large number of access machines. Having set up the model with no clear partition, the IP address is also very easy to cause an IP conflict, the same IP prevents the computer from accessing the network. In this case we need to change the IP address for one of the 2 duplicate machines and of course the problem is not just about changing the IP address to fix the problem. In this article, ElectrodealPro will show you the common cases and errors as well as ways to fix IP conflicts on your computer.
Fix error of IP conflict on the computer, unable to access the network due to IP conflict
Some common error messages when an IP conflict occurs:
“There is an IP address conflict with another system on the network”: There is an IP conflict with another system on the network
“This IP address is already in use on the network. Please reconfigure a different IP address. ”: This IP address is already in use. Please set another address.
Several causes of IP conflicts
-Two computers set up the same static IP address.
-A computer set up a static IP address to coincide with an address that was set by DHCP for another computer in the system.
-Laptop is turned on from sleep state. Meanwhile, another computer is using the IP address that the laptop used before sleep.
When the computer has multiple network adapters, there is a high chance that the computer will have an IP address conflict with itself.
-When multiple wireless connections are established in the system and DHCP is enabled on more than one device.
Method 1: Refresh the IP address
Step 1: Refresh the IP address on the computer using the command prompt. Into the section Start and type CMD.
Step 2: When the program window appears, type the command to delete the current IP address: “ipconfig / release“.Depending on the number of adapters installed on the device, the system will display different results:
Note: If the computer set up a static IP address, the message of failure command will appear: The operation failed as no adapter is in the state permissible for this operation. In this case, skip and move on Method 2.
Step 3: After deleting the old IP address, we will refresh the IP address by entering the command: “ipconfig / renew“
The new IP address will appear on the line IPv4 Address.
Method 2: Reset static IP address
When the computer uses a static IP address, you can manually switch to a new IP address that does not coincide with other computers in the system, using DHCP to the system to set up a new IP address.
Step 1: Into the Control Panel =>Network and Sharing Center. In the left column, select Change adapter settings.
Step 2: Right click on the network the computer is using. Choose “Properties“.
Step 3: In the window that appears, select InternetProtocol Version 4 (TCP / IPv4) then press the button Properties.
Step 4: Here, you can choose to have the system get the new IP address from the DHCP server (choose Obtain an IP address automatically) or manually enter a new static IP address (choose: Use the following IP address).
If you do not know how to manually set up a static IP, you should let the system automatically set up a new IP. DHCP will automatically detect available IP addresses and set the computer an address that does not conflict.
If you have tried both of the above and still cannot connect to the network, chances are the problem is with the router.
Method 3: Wireless Router
One of the simplest ways to resolve IP conflicts is to restart the wireless router.
When the router is turned on for weeks or months in a row, errors will arise. Restarting the router solves most of the errors. After rebooting the router, reboot your computer as well.
More rarely, an error occurs with a DHCP server when it assigns the computers identical IP addresses. In this case, it is best to upgrade the firmware of the router. Most computer users never upgrade the firmware to the router, so IP conflicts are easy to happen. The firmware installation is not easy, but if you are a tech person, you should give it a try to refresh your longtime router.
Above, ElectrodealPro instructed you how to fix the IP conflict on your computer, helping you change your new IP address so you can join the network. To learn about the network we need time and effort as well as certain research. For example, configuring TCP / IP using CMD, a frequently used tool to install and configure computer networks. If you want to update more about your network knowledge, see how configure TCP / IP using CMD to add knowledge for yourself. AND if in case your IP network has too many problems, you can also restore to the original state if you use Windows 10.
