Hi,

 

I've been tearing my hairs out with trying to get this ER605 working on my ISP's IPv6. The IPv6 worked just fine on my former TP-Link AX55 WiFi router, but never on the ER605. I tried it with and without the Omada hardware controller but it just won't go.

 

The following pic is from my AX55 router, which I reinstalled just now as a sanity check. It still works fine on IPv6 and tests ok on the net...

 

 

BUT when I try the same settings on the ER605 either directly or via the Omada Controller it never connects to the ISP's IPv6 and remains unrecognised by the ipv6-test site. And I've tried every thinkable option I can find. I'm no expert, but I really think the ER605 is broken... Never get any joy. See screen shots:

Paul

On my ER605 V1, I used the same settings as you, except Prefix - Get from Prefix Delegation, Prefix Delegation - WAN.

 

Note, by the way, as best I can tell, there are no IPv6 firewall features in the 605's.

  @Gary_E Thanks, and yes I've tried that as well as many other configurations. I was talking with my ISP's 2nd level support and they can't figure out why it's not connecting either. So maybe it's a bad box or firmware? I'll have to follow up with a formal support ticket with TP-Link when I return from vacation.

Cheers,

Paul

  @paulrob So weird. Maybe ISP binded your AX55's mac address of ipv6?

No, they haven’t. They’re fully BYO router so have no locked-down hardware.
