I will bet big money that something is not set quite right. I usually get that "unreadable configuration" message if I try to configure wirelessly, but can using an ethernet cable. So that's one thing. I've yet to be able to print wirelessly, primarily because I KNOW I'll have to mess around with the settings and I'm somewhat leery of doing so. But I will, one of these days.
My advice -- do a search not only on this forum but also on the Apple site discussion boards. I bet you'll find out what is wrong and -- more importantly -- how to fix it. And if you like/are able to troubleshoot on your own, I bet you'll find what you're looking for. And by the way, Apple just came out with upgraded firmware and software.
I am able to connect wirelessly and absolutely love it. (I'd love it even more if I could print, too!) Sometimes the AEBS connection is somewhat flaky, which is irksome. But it really is very, very nice to be able to connect without wires.
Good luck.
