Also, go back to your Quic portal and check on that popup where you can see your active connection for the delegatedIPv6Prefix. This will tell you if it's setup on Quic's side:

What happens if you change IPv6 LAN Assigned Type to SLAAC+Stateless DHCP?

Have you restarted the router and the client machine after the change?

Do you see the IPv6 Geekzone logo at all when you visit our pages, like my one?

Did you buy this TP-Link router to replace the previous TP-Link model you had? Or borrowed it?

You could plug a computer directly into the ONT (swap the router and computer) and see if you get IPv6 on the client.

Just make sure to configure the client correctly as needed (VLAN10 if in use, PPPoE if in use).

You have to be sure the TP-Link router is not the problem.

Thanks, got the PM. PC not on IPv6 direct to ONT. Do you have another device to test, like a phone via WiFi to router to rule out the client?

Plugged a second computer into ont-no ipv6. No ipv6 for that computer either once connected via router. Same with phone via wifi.

Maybe this will help to see what is happening. Tests to ipv4 and then ipv6 sites.

The issue is nothing to do with speeds. My routers also loses its IPv6 connection every few days on Quic. Same Edgerouter worked fine for years on Vocus and for several months on Quic. Started playing up in ~Jan and was recommended by Quic Discord to invest into a better router -- Mikrotik -- as the consensus was that the Edgerouter was the cluprit. Got that and still seeing the same IPvb6 drops after a few says so am now more confident it is not a router issue given the config I'm using on the Mikrotik is the same as what other Quic customers are using.

Someone in the Quic Discord kindly let me know of a Mikrotik script that can automatically bonce my IPv6 connection. Not a great solution and no help to the OP of this thread. Quic really need to own up to whatever issues they are having and give us a timeframe for when it'll be fixed.

Yeah, same here with Mikrotik. DHCP lease seems to expire and not able to renew until router restart.

This is off-topic but I've got 2x Mikrotik's on Quic connections and they both have zero issues.

However, I'm statically assigning my pools and are not reliant on DHCPv6. I think this more affects people who do not have a static /56.

One awkward thing about Quic is the lack of an official compatibility list of routers & configuration instructions. There's no "this router model + configuration is guaranteed to work."

Ironically in your case, the only router models mentioned on their support page are ASUS routers, and the EdgeRouter... yet you've had advice from other customers that the Edgerouter doesn't work properly with Quic v6!
