To get ipv6 working, use the wan and DHCP settings below. the DNS servers are cloudflare and google and seem to be more reliable than the telus servers. you can get a list of public dns servers https://duckduckgo.com/?q=public+dns&t=hk&ia=answer
for ease of copy paste: 2606:4700:4700::1111 2001:4860:4860::8888

stateless for dhcp. statefull will also work but probably best avoided.

Save your settings. Then REBOOT THE ROUTER.
then reboot your computer, or at least ipconfig /release and reconnect to the wireless .
