Hello,

Use a Time Capsule without attaching it to a router. Every now and then, you need to back up to a Time Capsule, but you don't have access to the router, or a wired network jack. You've got to go 100% wireless. I discovered a way to set it up 100% wirelessly, with no cables attached.

Thank You.
