Included in what I have tried is two other mesh router systems from Asus and TP-Link and IPv6 support is rock solid on both and do not give me "not available" messages when the IP is renewed by the ISP. Please do not suggest I try anything except fixed firmware for my otherwise great RBR850 system.

    Thanks The download link for the router FW 4.6.14.3 doesn't work. The one for the satellite does.

        Got the firmware updated. Same IPv6 problem: IPv6 becomes "Not available" after a few hours, sometimes a couple of days and in rare occasions up to a week. Again, I think the problem is DHCPv6 not working correctly on Netgear routers so when the ISP updates the router fails getting the new IP.
