DrMagnetoR - Your method of interconnecting Time Capsule with the Verizon FiOS router works beautifully. All the Apple Geniuses would tell me was to connect my TC WAN port to the VZ LAN port. Not enuf. Who knew I should go into the router settings and TURN OFF the Wi-Fi on the router? The newest router, incidentally, has the user name (admin) and the password (about 7 digits) clearly on the label -- not so on earlier routers (I've had four now in the past two years).
Your post is three years old, but it is still very timely. Thanks.
