Hello, I have an older AirPort Extreme that has not been setup for several years. i'm trying to set it up now but can't because my Airport Utility is too new and the firmware is too old. This version of AirPort Utility requires this AirPort Extreme use firmware version 7.3.1 or later. Go to AirPort Service and Support for more information. is the message that i receive. any help would be greatly appreciated. thanks!
