Trouble connecting Apple Time Capsule to existing wireless network

Having issues connecting my apple time capsule to my existing wireless network.

Last week the ISP came in a changed the modem. If I plug a computer (with LAN) directly to the modem, the Internet works. However, when I plug the Time Capsule into the modem, the Internet doesn't work. This is what I get:

NOTE: I have NOT gone through the airport utility to change anything yet. I assumed all should have been "good to go" with simply plugging the time capsule into the modem, but apparently not. I just to want to start re-configuring things and make it even worse.

Everything worked fine with the old modem. What would be my first steps to get back online? I'm using Yosemite on a Macbook Pro Retina.

Thanks!

What IP address do you get when you connect a computer directly to the modem? (You can find that out from the network preferences panel.)

If it is in the range

10.0.0.0 -- 10.255.255.255 or
172.16.0.0 -- 172.31.255.255 or
192.168.0.0 – 192.168.255.255

then your modem is also functioning as a router, and the Time Capsule needs to be set to Bridge Mode. Otherwise, it needs to be set to "DHCP and NAT".

Let us know which it is and we can send you instructions to set it up.

As well, make sure the cable from the modem is plugged into the WAN port of the Time Capsule.
