You should have the appropriate utilities already installed at /Applications/Utilities/. If you don't have any Airport utilities, try installing the Airport software, URL below. In general, you don't need the software CD that comes with most Apple accessories - be it Airport cards or base stations, iPods, iSight, displays, etc. etc. etc. Most of the time, the necessary software is part of a default installation. http://www.apple.com/support/downloads/airport401formac.html "Invasion of Piracy" <LOREN at flash.net> writes: > Does anyone here use an Airport Express?
