Windows 10: IPv6 Looses Connectivity on Reboot

Everytime I fully shut down my computer or reboot it, my IPv6 internet keeps dropping. I do have IPv6 from my ISP and I am using Google's public DNS servers for my IPv6. Everytime it looses connectivity, it still remains connected to the network but the connection then switches to IPv4. Can I get some information on how to fix this?

1511 update, lose IPv6 connectivity a few minutes after reboot

I've installed the 1511 update (threshold 2) on my desktop computer. It has always worked correctly with my dual stack IPv4 and IPv6 LAN, with both Windows 8 and Windows 10. Now, after the update, it
will initially have IPv6 working after I reboot. Then, after a few minutes, IPv6 will stop working, and I see "no internet connectivity" for IPv6 from the Network and Sharing connection properties, even though the other clients in my house still have IPv6
connectivity.

So far, I've tried using netsh to reset the winsock catalog and the tcp stack, and have installed the latest network interface driver from the OEM. I also tried disabling IPv4, and seeing if the network
troubleshooter could get the IPv6 connectivity going. That didn't help, either.

At this point, this behavior is a mystery to me. Right now, no IPv6 on this desktop. If I rebooted the computer, IPv6 connectivity would be restored for a few minutes...I have no idea how to troubleshoot
this one, it's just strange.

Any help or ideas on what directions to go with this?

Thanks!

 

Network Connectivity

Don't install anything else. Deactivate IPv6 on your network device, so in the end you use only IPv4 addressing. In 89% of all network connection problems it is a faulty IPv6 implementation. Do not forget to reboot.

 

What type router are you using? It may need a firmware upgrade.

 

I checked and none need a firmware upgrade. I am able to restore IPv6 connection manually but it becomes a pain.

I have two routers, the first one is a ARRIS Modem/Router TG1672G.
Then I have one upstairs that uses a bridging function, a Netgear R6200v2 to connect to the ARRIS one.

Both support IPv6

 

Yes, that can be a pain. How does it act when you set the DNS to auto configure, instead of google dns?

 

It gets the IPv6 DNS from my ISP. That doesn't change it from auto disabling on every reboot.

 

Have you considered using open source firmware, IE DD-WRT or Tomato?

 

Not really, I don't know if I want to replace my router's firmware. Is one of them not compatible with IPv6?

 

I think the netgear one is. The Arris one I belive come from your ISP and will not be supported.

I found this for the Netgear, I have to say it's use at your own risk. I flashed my Linksys router and it has worked great.

Does it have the same functions? I do need bridging support.

I don't understand why the router can't keep IPv6 up.

 

Yes it does
