I was going with the c 7000 but would like to future proof myself and not have to get another routermodem combo in the future when the internal bits fail . I am currently on the rental combo from xfinity and even after port forwarding and changing the name of the second Xbox in the Xbox settings I still get one open and one moderate NAT . For me , it ' s time to upgrade to a more capable setup . Just so you know the CM 600 was replaced by the CM 700 . CM 700 is a 32 x 8 modem , DOCSIS 3 . 0 with max download speeds of 1 . 4 Gbps .
