The update you sent is lovely, except I can tell you that the one (also an Arris, running DOCSIS 3.0) which was 
installed in late October in my house in Washington simply does not run v6 with the pre-installed load.
In this particular case "C4 CMTSes" is the important bit of that update. The CMTS is what your modem connects to on the other end. You might be connected to a different type of CMTS which doesn't support or isn't configured for IPv6. You wouldn't be able to know that without contacting someone with a good knowledge of the network at Comcast though.

It could be as you say, that the modem only supports it when wireless is disabled and that is the only thing stopping it from working for you. If that was the case I would ask for a different modem, or go buy a modem that you think will work.
