What is this? Pop up in Safari with red warning sign saying something about an ip address?

I think that kj4btkljv is probably right that you simply had an issue with a duplicate IP address.

If this is what you saw then it was just a minor IP conflict with another machine on your network,
Not a problem if it went away.

I have seven devices on my network and I've never seen one of those.

Now it's troubleshooting time, Gene. That should not happen.

How would I do that, AA? I don't have a clue as to what caused this to happen and how to find out from whence the problem came.

Thanks for any ideas about how to "troubleshoot."

First step in troubleshooting for me would be to check which if any machines have fixed IP addresses and which get assigned addresses through DHCP or whatever other means. Then check to make certain none of the fixed IP addresses are in the range assigned through DHCP. The settings for DHCP assigned addresses vary by model of router.

I find that it happens with Netgear routers that I've had.

Is this Chinese that you are speaking? I'm afraid that I don't know anything about IP addresses or DHCP.

Can you be more specific in describing how to check the the things that you are recommending ?

Exactly the advice I was going to offer.

Gene, if you don't have a specific requirement to have a device(s) use a static IP address, you'd be much better off setting all clients to use DHCP and let the router assign addresses as needed.
