I have a weird situation where the Airport Utility (either on the iPhone or my iMac) does not see my primary Airport Extreme base station, but I can reach it by entering it's IP address and password in the "Configure Other" dialog box. Strangely, the Airport Utility does show the two Airport Express units that I am using to extend my network for a few things that need an Ethernet connection. Those show as "green dot" and every thing is able to reach the Internet.
Any ideas?
