using airport time capsule with at&t u-verse
I'm going to be ordering AT&T u-verse which requires the use of their gateway wi-fi modem. I want to continue to use my airport time capsule as my network router. How do I set this up? Do I disable the wifi in the AT&T gateway modem and if so how do I do that? Do I conntect the at&t modem to my time capsule the same way my current cable modem is connected, via the O ethernet port? How do I setup my time capsule using airport utility 6.1? It's currently setup with DHCP, does that need to be changed?
