Time Capsule unavailable
Why can't I connect to my Time Capsule? I see it in my shared network, but it says that its unavailable.
MacBook Pro with Retina display, OS X Yosemite (10.10.1)
This has been an ongoing issue with Yosemite. The latest release 10.10.2 still does not seem to resolve it. There are no known permanent solutions. The only work around is to restart the base station when the communication with it is lost. This could be daily or, if you're lucky, every 3-4 days.
