R6120, IPv6 not working, tried Auto Detect, Auto Config and DHCP

I've tried Auto Detect, Auto Config and DHCP and none of them work for getting IPv6 access. My ISP fully supports IPv6 and I had no problem with IPv6 access from my previous Linksys router. Any suggestions would be greatly appreciated.

      Cable modem is Motorola MB7220, ISP is COX Communications, these are the same as when I was able to use IPv6 with my Linksys router. As for the Gateway, following is the information I get when I display the IPv6 routing table (Linux):

       

      Kernel IPv6 routing table
      Destination Next Hop Flag Met Ref Use If
      ::1/128 :: U 256 1 0 lo
      fe80::/64 :: U 600 2 0 wlp1s0
      ::/0 :: !n -1 1 0 lo
      ::1/128 :: Un 0 5 0 lo
      fe80::7351:7b10:7959:6626/128 :: Un 0 2 0 wlp1s0
      ff00::/8 :: U 256 6 0 wlp1s0
      ::/0 :: !n -1 1 0 lo

    My cable modem is a Motorola MB7220, my ISP is COX communications. These haven't changed since I was last able to use IPv6 with my Linksys router. Below is the IPv6 routing table:
