I have a Netgear router that is connected to a Modem. DHCP is enabled. Originally, the ip address of the router was 192.168.1.1. Recently, about once a week, the router keeps saying there is an ip conflict with the ISP's ip address and therefore, the router then changes it's ip of 192.168.1.1 to 10.0.0.1. What I don't understand is when I go into the router and look at the WAN ip, it's not 192.168.1.1. Not very close. Anyone know how I can turn this off so the router doesn't change it's ip address. Normally I wouldn't care but there is a large Konica printer\scanner that has already been configured on the 19.168.1.1 network and I'd rather not have to figure out how to change all those settings. Thank You.

Does that change any of your recommendations?
Thank You.
Strange that it would choose 10.x.x.x. as these routers usually default (from the manufacturer) to a 192.168.x.x address. Have you tried resetting the device back to factory defaults and then seeing how it behaves? You should be able to back up the config (save config) to a TFTP server before you do this (but I would manually set it up again and not rely on the reloading the config).
One pc on the network has a static ip of 192.168.150
One network printer has static ip of 192.168.1.99
HOWEVER, four weeks ago when this problem started I looked for a firmware update to the router and there was not one. I just looked again and guess what? There was one. HMMMM,
thats the only thing that makes sense. Would you agree?

On the other hand, is this a wireless router? It could be that someone is jumping on it with a conflicting address in that case.

Some routers will offer a log section to review. You might find something there showing what is happening. The only problem is that these are usually first in, first out and might clear on a reset. I'd check it though. It might show you a MAC Address of something that is conflicting.

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.
