What does it mean when Windows detects a conflict of IP address on the network?

by on March 13, 2012

Q: Hi, I have an error message on my vista run laptop: Windows detects a conflict of IP address on the network. I wonder how this can be as it’s only 1 laptop on the network?? I use an Ethernet cable with modem and when that won’t work thanks to the error message I revert to using my dongle which works fine. Cheers!

    Try restarting your modem.

    From a Windows command prompt (click start> Run… and type in cmd )

    Type in the following commands:

    ipconfig /release
    ipconfig /renew

    If you’re still having problems, copy/paste the output of those two commands into a comment here.

    It sounds like you may have bound the same IP Address to both your wireless NIC and ethernet NIC. When there is an IP Conflict on the network this can cause network connectivity issues as it seems you have found out.

    If both of your NIC’s are set to obtain the IP address automatically I would suggest to check your router/wireless router Logs and verify that your computer name/IP Address is the only computer connected to the router as you stated that there is one computer on the network.
