We have 3 computers in the home sharing a single internet connection. It keeps getting cut off, and the error message says that there's an IP conflict with another computer. We get that for all three computers from time to time. What should I do to fix it? Any suggestion will be appreciated.

Hi Firefly,

An IP address conflict occurs if two or more computers in a network get assigned the same IP address. Since you mentioned that you have 3 computers sharing a single internet connection, this means that these 3 computers must be connected to a single router.

The router is responsible for assigning IP addresses to the computers attached to it, and it should work in a way that it should not give the same IP address to more than one computer.

One solution here is by running these commands:

IPCONFIG /RELEASE

And then

IPCONFIG /RENEW

Doing this will make your computer ask for a new unique IP address from your router, thereby fixing the issue. You may need to do this on all the computers getting the error.

If the error occurs often you may need to upgrade the firmware of your router.

Hi Firefly,

It is possible that the 3 computers you have is not set to a Dynamic IP address which will change every time you connect to the internet. You also did not mention what kind of networking device you are currently using.

However, if you are using a router, not a switch or a hub, then ideally the router will automatically assign a different IP address for each computer every time you connect to the internet.

Here is how you can set them to dynamic.

  1. Open control panel.
  2. Choose network and internet connections.
  3. Choose network connections.
  4. On the network connection Window, choose the general tab (for LAN connection) or Networking (other connection).
  5. Choose internet protocol (TCP/IP), then properties.
  6. Choose obtain an IP address automatically.

If this does not fix the issue, go to the command prompt by clicking start – run – cmd then press enter.

At the command prompt please type in:

  1. Ipconfig /flushdns then enter.
  2. Ipconfig /release then enters.
  3. Ipconfig /renew then enter.

This will let you have a new IP address. Afterward repeat the procedure on how to obtain an IP address automatically.

Thanks,
