Can an AirPort Extreme (5th, last "flat" model) not be setup via WiFi?

both my gen1 and gen4 had to have WPA2 turned on and a password chosen
my gen4 got zapped by lightning
I may have set up the Gen1 by cable as my G4 laptop didn't have a airport card at the time but I don't recall the menu being any different because of it
