I posted in a new thread as the old thread has been closed, but I wanted to let everyone know that it's been 7 weeks of perfect availability for IPv6 - not once have I had to auto detect/get a new IP address because IPv6 was down! This all coincided with 4.6.14.3 coming out,. I have no way of knowing was this Netgear, Comcast, or both collaborating to fix it - anyway, I feel confident now saying this is fixed. I hope others who were suffering are seeing similar results!
