Hi HELLO_wORLD,
Thanks for your assistance.
Setup is RBR50 and RBS50 wired back haul. Router mode. IPv6 WAN side is Auto Config. Router's IPv6 address on WAN displays Not Available. In the past I could click Apply and it would find and IPv6 IP and start working again.
I have tried using Get Automatically from ISP and manually adding Cloudfare IPv6. LAN is set to DHCP. Below is the returns from the commands.
