said by EG:FWIW, that device does not yet appear to be on their *Approved Modems List*.
True, but there are no Netgear modems or gateways on the business class approved modems list, and apparently someone from Comcast has proposed using a Netgear box to solve the problem being seen by pflog.
It is possible that this Netgear box may be under testing and consideration as a replacement for the SMCD3G-CCR which is apparently not being very cooperative in working with Comcast's native IPv4/IPv6 dual stack.
