AirPort Utility cannot find base station?
I've dug out an old AirPort Express 802.11/n base station, to use as a wifi provider from our work Cisco 800 series router (which has no wifi).
Connected to router, powered up, constant flashing amber light. Open up AirPort Utlity on my iPhone. Green light = Internet. Message at bottom of phone screen says "No AirPort base stations have been found. AirPort Utility will conntinue searching."
Phone is right next to bast station, shouldn't need ot look very hard!
So, I have good internet connection between base station and phone, but flashing amber on base station. On iPhone wifi settings , it shows the connection as an unsecured network.
How can I set the base station up with with security and password?
