Anyone have any issues with Time Capsule and a ARRIS SURFboard SB6121 DOCSIS 3.0 Cable Modem?

I'm going to be getting Comcast. The modem I was told to purchase was ARRIS SURFboard SB6121 DOCSIS 3.0 Cable Modem.

Has anyone had any issues hook up the time capsule with this modem?

Thanks in advance!

Airport Time Capsule 802.11ac

From a cox rep named Askin6305B on DSLreprts.com "7.6.7 and 7.7.7 are the same thing built for different platforms. And no, none of those notes mention the specific fixes that went in related to IPv6 and DNS but they are in there. We've confirmed this with Apple." It wasn't just Arris/Mototrola's, it had to do w/ some IPv6 stuff between Cox/Apple. I've adjusted my IPv6 settings in network/airport utility, and I'll post if there's still problems.
