Airport Utility unable to read AirPort Extreme Config
I have a brand-new Airport Extreme, 5th generation. I am trying to configure it using AirPort Utility, but utility is unable to read the device configurations. I bought the Extreme to fix what I thought was a failed old AirPort Express. The Express one day stopped working. After resetting it, AirPort Utility was unable to read the device configurations, just like the new Extreme.
I have an iMac 8,1 with an AirPort Extreme card, OS 10.6.8, AirPort Utility 5.5.3 and Airport has 7.5.2 firmware aboard.
I am at my wits end on this one. Any suggestions?
At the moment, Utility persists in claiming that there is an Extreme base station connected, even though I have unplugged the power.
iMac, Mac OS X (10.6.8), 4GB RAM
