Time Capsule cannot be accessed but Time Machine connects Ok
I have a time capsule to which I backup to via Time Machine.
This is working Ok, but I noticed yesterday that the Airport Utility app was saying the capsule cannot be found (Time machine still backs up to it). Today the capsule isn't showing in the Airport app at all (but Time Machine is still backing up to it). If I look in Finder > Network it shows the capsule cannot be connected to.
Slightly puzzled to say the least? What could have gone wrong?
