I have bought a new Apple Airport Extreme router to extend the wifi network. After initial setup (security WP/WAP2 Personal) I cannot access it from any apple device (I've tried several iphones and iMac) saying "Incorrect password". I have verified, changed, reset everything: passwords, network connections, devices... The router works when there is no security but cannot be accessed when securized (both 2Ghz and 5GHz channels).
