SB6580 arrived yesterday afternoon.
I installed it myself, first powering all things off (and removing the battery from the Arris modem). This included my PC, Arris modem, and my old Netgear WNR3500 router (which was being removed, to be replaced by the SB6580).
Then I disconnected the cable coax from the Arris modem and screwed it onto a splitter, and then fed the two outputs from the splitter to both the Arris modem and the new SB6580.
Then powered up things, with PC last.
Not surprisingly, I still had phone service (through the Arris modem).
And I was also able to use Firefox to communicate with the new SB6580 (via documented 192.168.100.1 or 192.168.0.1 as is shown by IPCONFIG). I explored around a bit in the Motorola firmware (it's clunkier than the Netgear firmware, but still usable) and changed a few settings per my setup.
Then I called TWC to get them to activate the SB6580 (and remove Internet from my Arris modem so that I would no longer be charged $3.95/month). They must be having thousands of these requests, because they actually have a special announcement on the recording offering "more info, if you've recently bought your own modem". At the end of this little blurb (which simply asks that you have your HFC MAC address from the bottom of the modem available for the technician) they even have a "press 1 if you want to talk to a technician to activate your modem"), which is all surprisingly thoughtful and convenient.
So, in just a few moments I was talking to a knowledgeable tech, who did everything he needed to do (which included sending out "reset" instructions to the SB6580, etc.). Within minutes my account had been updated to reflect the Arris modem now only used for phone, and the new SB6580 was now bonded to TWC and fully functional! Everything was now operating normally.
All of my home LAN devices are set for "automatic DHCP" lease assignment of IP addresses, so they didn't have a problem when powered on now that they were on a 192.168.0.* LAN scheme, rather than the 192.168.1.* scheme formerly used by the Netgear WNR3500.
And that's it! Up and running. I've run some Speedtest timings and it's absolutely top notch for what I'm paying for (Turbo, 15Mbps down, 2Mbps up). It actually does seem to be "snappier" when going to new URL's than it was when I was using my old Netgear WNR3500 through the Arris modem. Perhaps this DOCSIS 3.0 and latest-and-greatest modem/router technology from Motorola makes a small difference in high-speed performance. I don't think I'm connected to a different/faster DNS, but whatever the explanation I'd have to say that subjectively it seems "faster".
Whatever... I'M HAPPY! Up and running without a problem.
