How do I swap out an old Airport Express for a new one?
I am trying to replace my very old Airport Express with a new one (802.11n). I tried setting it up with AirPort Utility, but without success. I can't get past the flashing amber light. In what order do I disconnect the old Express and connect the new one? How can I use the "replace an existing base station" option if both the old and the new Express are not plugged in at the same time? TIA for any help.
AirPort Express Base Station, OS X Yosemite (10.10.4)
