BN. That's interesting.
If I run the Airport Utility (Finder/utilities/Airport) the utility finds the Airport TC and offers me 3 options.
1. Create a new network (would not want this I presume)
2. Add to an existing Network (would want this I would have thought)
3. Replace an existing device (would not want this I would have thought)
If I select option 2, and hit 'Next', the next page has the heading 'This Time Capsule will create a Network'. Since I think I should be looking to join an existing network, or extend an existing network, this does not look right and I bale out at this point. Any thoughts?
PS. I have an Airport Express to be able to stream audio to my old, but nice, analogue hifi - it is currently switched off to ensure it is not affecting matters.
