Hi all, I just want to say thanks to everyone who chimed in on this discussion. I'm aware of the issues regarding the sharing of band width with cable modems and speed not usually matching the advertised speed, but still thought the time capsule wasn't doing what it should. I checked the network settings per Tim's instructions and they looked OK, so did a reset of the time capsule this afternoon, and our performance seems to have improved. At least now, we're in the ball park of the advertised speed, which is what I hoped for.
Again, thanks everyone.
