Technicolor/Cisco DPC3939 IPv6 ceases to route and Prefix Delegation changes

Hello,

The following post describes exactly what I am experiencing with my DPC3939.

https://forums.businesshelp.comcast.com/conversations/ipv6/newbie-guide-to-copper-business-static-ipv4ipv6-offerings-from-comcast/6084833f43a1b761d4e7f0e6

Specifically:

"DHCPv6-PD works immediately after reboot then stops routing later on until power-cycled again."

Also, it changes the Prefix Delegation periodically.  Really messes up my network.

When is there going to be a fix?  

Thanks

Kevin

Another very knowledgeable user has discovered that the Netgear CG3000CR is really the way to go.  It is older, but it it's IPv6 PD is more solid than any of the other CPE's you guys have.  How can I get a Netgear CG3000CR?

It looks like the ARRIS X5001 is also a cable modem (in addition to fibre).  Perhaps that might work...

Thanks

Kevin
