I just replaced an aging Airport with a new TimeCapsule. Installation was fine. MacBook (OS 10.6.8) recognized the TimeCapsule, and started backing things up on TimeMachine. The backup "timed out". And now, Airport no longer detects TimeCapsule, ALTHOUGH every machine in the house, including my MacBook and my Android phone, are feeding off of the internet via the TimeCapsule. (On the other hand, one of the syncing functions between my phone and the computer no longer work).
The TimeCapsule's light is "green", and has never strayed from that.
In addition, my wife's MacBook Air DOES see the TimeCapsule (including the "Data" file from my original attempt to backup my computer -- we've not tried enabling Time Machine on her computer yet).
I'm stumped and frustrated! Any ideas?
