How to Troubleshoot “Windows has detected an IP address conflict” Error Message

by

Like any other computer, your computer gets an IP address when it connects to a network or the Internet. An IP address is a unique address and identifier for your computer. The IP address system allows networks (or the Internet in general) to distinguish and recognize computers. Therefore, in theory, no two computers on a given network (or on the Internet in general) can (or should) have the same IP address.

What causes the “Windows has detected an IP address conflict” message?

Each device that connects to the network is assigned a unique number – an IP address – that allows it to be recognized and communicated with. So, theoretically, no two devices can have the same IP address. But in practice, interference is always possible. Two or more devices may have the same IP address because of a faulty router, computer settings, or even problems with the Internet service provider. read more

How to Restore IP Address Starting with 169.254 Problem

If your computer is set to “Obtain an IP address automatically” and cannot find a DHCP server, it will probably generate an IP address similar to this address 169.254.x.x. Some modems are a combination of a router and a modem, so you may only have one device. In all cases, the router handles DHCP.

Your Windows computer must obtain some sort of IP address from the DHCP server. If that process fails, it gives up and uses Automatic Private IP Addressing (APIPA) to generate its own. This often results in your computer not being able to connect to the Internet or see other computers on your local network. This problem with IP address 169.254.x.x can have many causes. read more
