Help with Time Capsule with a new modem

First off is the modem configured as a router, or just as a modem? You may not know the answer but if you look up the brand & model number of your modem we can make an educated guess on that.

In a nutshell, your Time Capsule can be configured as a router, or as just a wifi access point. You must have a router on your network, but ideally you only want one - so if your modem is also a router, you should enable the router feature only on one of them (the modem or the TC). On the TC that's done on the Network tab of the AirPort utility, set Router Mode typically to "DHCP and NAT" (to use it as a router) or "Off (Bridge Mode)" if your modem will be your router.

The other thing to check is the Internet tab in the AirPort utility, normally you set Connect Using to "DHCP" but there can be exceptions.

try unplugging your modem and airport (time capsule) for about 30 seconds, hopefully that should sort everything out.

if that doesn't work, go into airport utility open the internet tab, what does the "connect using" option say.

Then you've configured it as an access point. I'd suggest that you read the setup guide, page 13ff.
