Hello all, i have searched and searched and still can't find an answer to my questions. I am trying to setup airport express with my speakers (airtunes)... I have an airport extreme base station (802.11n) and it works just fine with my MBP and my wife's MB. When I start AirPort Setup assistant.... "In order to use the AirPort Setup Assistant your AirPort card must be enabled and AirPort needs to be turned on and set to use DHCP. Click OK if you would like to change these settings, or Skip if you would like to configure AirPort Base Stations using ethernet." when I click OK, the following comes up: "There was an error communicating with your AirPort card. Please make sure it is installed properly and try the AirPort Setup Assistant again." I have Airport Disk Utility, Airport Utility, and Airport Admin Utility for Graphite and Snow - i think they came with the airport extreme. I tried to run the airport setup assistant on the macbook as well, but the same thing happened. please help, it would be so greatly appreciated.
