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.

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.
