I just recently purchased my laptop so I am just learning. The message I got on the computer said, Another computer on this network has the same IP address as this computer. Contact your network administrator for help resolving this issue. More details are available in the Windows System event log. What does this mean and is this something important I need to fix. I would appreciate any help in this matter.

I see that message on my home network sometimes, and it's not critical.  If you have a home network, try powering off your router, waiting a few seconds, and powering it on.  If you're on a business network, consult with the network manager.

    Could this be caused by wi-fi? My usb modem is connected to my wi-fi router and I open the wi-fi whenever I want to browse the internet through my smartphone. The ip address on my smartphone is 192.168.2.101 while on my desktop pc is 192.168.2.100.

    Those 2 addresses do not conflict obviously. I suggest you look at it the same way I did go right to the connection you are using for the device you are on. My earlier post is from a Widows 7 perspective other OS may be different. When you open the Network Sharing Center you will see in the second section from the top on the right side you will see "connections: . following the steps outlined in my original post if you see that the configuration shows 2 "Internet Protocol Versions" active that will be where your conflict is coming from.

    Hi Rye,

    Thanks for your reply.  Not sure about the answer to your question, but maybe you might want to remove your IP addresses.  Maybe it's not a big problem and I don't know what I am talking about but I think that should remain private.  Just say'in
