I have an airport extreme n that is running fine. But I wanted to check some settings so I ran Airport Utility [5.2.2 (522.3)] to get them. It discovered the base station just fine. It returned the name, IP, software version (7.2.1) and airport ID. But when I click either "continue" or "manual setup" I get this: "An error occurred while reading the configuration. Please make sure your AirPort base station is plugged in and in range of your computer or connected via Ethernet and try again (-6722)" My base station is plugged in, it is in range and it is connected via Ethernet; otherwise, you wouldn't be reading this. Anybody have any idea what's going on?
