Orbi 872, IPv6 & Gigaclear

Question

Is there anyone on a Gigaclear service using IPv6 on this model Orbi and can help with the settings needed?

I've a case open with Gigaclear at the moment. I have a fixed IPv4 address.

Using a Linksys Velop router the IPv6 assignment was picked up quite happily (I think this was set to Auto or DHCP or similar but I don't have the router now as it had to be replaced and the Orbi took over, so can't check exactly) and the line based all the tests at

https://test-ipv6.run/

and

https://test-ipv6.com/

The Orbi however doesn't even see the IPv6 coming down the wire towards the WAN interface although Gigaclear confirm it's live on my line and the WAN interface stays resolutely blank (see the screen shot below)

I've tried all the various sensible settings under the IPv6 tab on the Orbi web interface but nothing works (ONT and router rebooted on each change and re-tested).

Anybody with this router and a Gigaclear line able to say "oh yes, it's this!" and has a working IPv6 setup would be really helpful?

TIA!

What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
Does Auto config or Static work?&nbsp;
&nbsp;
Does a ethernet connected PC see any IPv6 when connected to the RBR when Auto Config or DHCP is enabled for IPv6 on the RBR?&nbsp;

Thanks for picking up on this one.&nbsp;&nbsp;&gt;&gt; What Firmware version is currently loaded?&nbsp;V10.5.20.4_1.3.5&nbsp;&gt;&gt; What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?&nbsp;Adtran; the exact model is hidden behind a large desk ATM but the standard install from about 18 months ago.&nbsp;&gt;&gt; Does Auto config or Static work?&nbsp;&nbsp;Neither offer any IPv6 on the WAN, no.&nbsp;&gt;&gt; Does a ethernet connected PC see any IPv6 when connected to the RBR when Auto Config or DHCP is enabled for IPv6 on the RBR?&nbsp;&nbsp;No.

Would be good to get the Adran model# information.
Also can you connect one ethernet PC to the Adtran instead of the RBR and see if IPv6 is picked up by this one PC?&nbsp;
What region are you located?&nbsp;

I’m told that it’s an Adtran 621i XGS-PON ONT. There’s nothing obvious on the front of the unit.

I’m based in Cambridgeshire, but as far as I know, they Gigaclear system isn’t region specific.

Ok so UK region.&nbsp;NG is aware of current FW issues happening with IPv6. I recommend keeping IPv6 disabled for now until next FW update appears. Should be a v12 version that could have this fix included. Not sure when this new FW will be coming to your region. My region NA already has it and if all goes well, should be coming to the 870 series as well.&nbsp;

Might open a support ticket with NG support as well to let them know about this if you feel the need.
