Can Airport Extreme be set up in client mode?
I've set up the Express in client mode before but I am having trouble setting up the Extreme. During set up it sees that I am on an existing network but it bypasses that and asks me if I would like to create a new one. When I try and force it to connect to an existing network it says that an unexpected error occurred. I also tried to set it up as a new network and then went into Airport Utility to force it to connect to the existing network. It takes the password and restarts and then never reappears in Airport Utility after I switch back to the existing network.
