Please help with a dumb modem/router question

Im interested in the Time Capsule.

Right now Im using a Linksys modem/router combo. The Time Capsule has no coax in (because its not a modem).

Im assuming I would have to daisy chain the Time Capsule to the Linksys. Would this cause any problems or bottlenecks since both devices would basically be sending out WiFi signals?

How would this work?

All you need to do is disable the routing functions on the Linksys, and then you can use Time Capsule as usual.
