Deleting old wifi address
When I got our new time capsule, the Apple Care guy said that we had to set up a different WiFi (Apple Network) address than we had been using for the old Time Machine. The problem is that the old WiFi address won't go away - it keeps showing up on my iPhone, so that even when I'm using the new WiFi address, a message will pop up asking me whether I want to be on the old (defunct) wifi address. I've tried "forget this network" in WiFi settings but that doesn't help. This is more an annoyance than a problem but if there is a way to banish the old WiFi address forever, I'd love to do it.
