Hello, would anyone possibly know how to refresh or change the IP address of my Airport Extreme? I am talking about the one that you see when you open Airport Utility and click on the icon of the router. It seems that no matter what I do, the IP address is always the same- I've done all types of resets and even brought it back to the factory defaults, yet no matter what I do, it always stays the same. To elaborate, I have a cable modem that is plugged into the router. My cable modem provides a dynamic IP address. I know for a fact that it changes every so often sometimes even after just unplugging it for a few hours. When I plug the modem directly into my iMac, it displays the appropriate IP, however, when I put the router back into the equation, and check my IP address, it is always the one listed in airport utility as I mentioned in the beginning. Is that IP address specific to the hardware ??? I have even contacted apple willing to pay for the answer but after 25 minutes on hold, the rep came back with nothing. I have read about similar posts to mine, but none ever showed a real solution. Question is, what is dictating that IP address? Where is the problem, ISP side or Router? Any input is much appreciated as I've been racking my brain to find the solution. Oh and by the way, the whole reason I want to refresh it is because of security reasons. Many thanks.
