What so scary? LOL
In
Windows, you get a little notification. It goes Network error:
Windows has detected an IP address conflict. Another computer on this network
has the same
IP addressas this computer. When this happens, usually, you lose your connection to the network, or your connection becomes unstable.
-Every computer on a network must have a unique IP address. It’s the only way that the router can keep track of where a request for a new webpage or network resource comes from, and where information arriving from the network or from the Internet, is to be delivered.
Most IP address conflicts tend to sort themselves out. You may need to restart the computer to speed things along. If you’re not ready to reboot your computer, though, there is a manual way to fix a conflict: you need to go to the command prompt, and type in
ipconfig /release or
ipconfig /renew, and hit
Enter. It’s exactly the same thing that restarting your computer does; with this method, though, you have a more convenient way of achieving the effect.
If this doesn’t fix the problem, you can always go to the other device, and try the
ip config /release routine there; alternatively, you can restart the router. If you find that the problem occurs often, updating the firmware on your router can help.
-That message on 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.
