Q: "unexpected error" when adding Express to network

This is a common bug that has continued with Mavericks from earlier operating systems.

Please check this Apple support document to see if that might provide some help.

AirPort base station not seen or "An unexpected error occurred" appears in AirPort Utility 6.3

Another option.....if you have an iPad or iPhone handy......is to use that device to set up the AirPort Express devices, which often works better than AirPort Utility on a Mac.

I get the same response. I have osx10.8.5 and airport utility 6.3.1. I have had airport express a1392 extended to time capsule for playing speakers for about a year and today noticed not working. All the other airplay speakers work fine so I don't think it is iTunes. I have not changed anything. I have reset and reset to factory with same response. i have tried IPAD ios7.1.2 with airport1.3.4 which never recognizes the airport express. I am in link local so above document noted. Any ideas would be appreciated

If you have reset the AirPort Express back to factory default settings.......

Go to the home screen on the iPad

Tap Settings'

Tap WiFi

Look for a setting for Setup a New AirPort Base Station

Tap on AirPort Express

The setup utility will guide you through

Thanks!!! That worked!

Thanks, but you already told us this above.

I was answering the question from Bga526.....who said that he had an iPad.

Bob, it seems to me you are very knowledgeable on setting up Airports; hence, may I ask you 2 questions?

1. Airport Express configuration failure on Yosemite

2. Setting up a A1088 Airport Express on Yosemite

Thank you in advance!

Thank you BOb

after having reset the station several times and not being able to have the express join the existing network, I tried with my iphone and it worked. I would never have thought of this solution. Thank you very much!
