I have Comcast in Kirkland, WA and I have been using the Motorola SB6121 modem. It works great, but requires a router to divide up the connection and create Wi-Fi access. So I looked into the SBG6580 and decided to get that for an all-in-one solution for my networking needs.
My SB6121 had been giving me IPV6 addresses and tested fine on the following website: »test-ipv6.com/
However, now I am using the SBG6580 and the same test says I don't have IPV6.
What am I missing here?
