I recently moved and I have 5 airport expresses that I am trying to set up. A few of them are older versions, and Airport Utility does not allow me to change their settings. I just want to change their name so I can tell what room they are in. I have version 6.1, but Airport Utility, states that this version does not support this AE, download Airport Utility 5.6, but version 5.6 doesn't work with Osx 10.8. Any solutions? thanks for any help.
