Early report after 12 hours, 

 

came from .31 firmware. Flashed dirty with latest version. After several manual reboots, I still have IPV6 working. I had a few times that it disconnected and reconnected, but still working, confirmed.


RBKE964

IPV6 enabled.


I will update the report after 48 hours or if something should happen.

Sad to report...

 

IPV6 issues starting to show around the 16 hr. mark for me.

 

I then performed a factory reset including fresh firmware flashes w/30 sec. resets for all 4 sats, and 1 router.  Setup from scratch(2.5 hrs)

 

After all that, (IPV6 still broken) for me, only on android devices now? IDKY..

 

So for security reasons, I have chosen to disable IPV6 for now.

 

Here's my repost update....

 

So close.....

    Thought so, sorry to hear that actually but expected. I have tried and tried to troubleshoot only to conclude Netgear needs to repair it. Since last February with the release of v.7.2.7.15 it has been broken. Figured they would have this resolved by now...

    Whos your ISP? 

    Were you using ISP Detected IPv6 DNS or custom DNS?

    Which IPv6 mode were you using for IPv6?

      Were you using ISP Detected IPv6 DNS or custom DNS? ISP detected 


      Which IPv6 mode were you using for IPv6? 6to4 tunnel (my local ISP says that our IPv6 is semi functioning)

        Ok.


        Something you can try, select a custom IPv6 DNS service for addresses, something like Cloudfare or Quad9.

         

        Ya, all this IPv6 stuff is two parts, ISP and router Mfr. Been a problem for a while now. NG is working on there side. 

         

        Does Auto Config or DHCP modes change anything?
