I decided it was time to take the Time Capsule and one of the iPods to the local Mac Store, for repair of the Time Capsule. Everything worked fine! I came back home and rechecked the home for all the things in this article: http://support.apple.com/kb/HT1365 and once again found none.
The Mac technician's suggeston was to try specifying the channel, as opposed to letting the Time Capsule automatically choose the "best" one. It worked! (I chose channel 8, since I had not seen it used by my networks or neighbors' when I looked in System Profiler.)
Just adding this post in case it helps someone else.
