I'm still using the original FW version 2.00NA, and I'm very pleased with its overall performance since I don't have an immediate need for IPv6 compatibility at this time, although it is supported by Charter at this location and supported by my particular cable modem (Motorola SB6121).
I'm still wishing to learn from this forum about a updated rock-solid firmware release whereby IPv6 compatiblity is supported. If I upgraded at this time I'd use version 2.13NA.
What's latest firmware forecast pertaining to the DIR-655?
Mark.
