IPv6 still broken

[donawalt]

Well, this morning I turned IPv6 back on after having it off for around 2 weeks, as I was losing the connection even though all the settings looked fine on the RBR850 web page.  I turned it on at 7:30, less than three hours later I checked IPv6 again, and it's failing. The router web page shows a WAN and LAN IPv6 address, DNS is automatic from ISP,  IP address assignment is Auto Config. Everything else is working great on the network.

So I guess until or unless something comes down as a fix, I am leaving it off. And if we get to the point we must have IPv6 working, I guess I will be forced to go with another router?

What modem/gateway do you have? 

I've had ipv6 enabled on my RBK752 and RBKE963 systems without a drop. 

(don't have an 8 series to play with). 

What firmware version are you on?

Modem is Netgear CM1200. Firmware version is V4.6.8.2_2.1.9. It was fine for at least a year. Like I said, a number off people with Netgear on Comcast are having issues. Problem is, nobody its fessing up to the problem...
