Not quite-- I need the Express Setup Assistant too
Actually, law guy, you still need the Airport Express Setup Assistant if you want to configure multiple Airport Express units. At least, there is no way that I can figure out to do it otherwise.
I have the same problem that skyton has. I absolutely cannot get ahold of the Airport Express Setup Assistant script. It isn't in the Airport software, wasn't included in the CD that came along with either of my two Express units, and apparently cannot be downloaded from anywhere on the web. I am desperately hoping that someone will email me a copy of the silly thing so that I can get my second Express working.
Any kind souls out there willing to zip it up and send a copy to me, I'd really appreciate it! (spambait@seraphine.us)
