      Hello. I'm new at this ipv6 stuff. I managed to get native ipv6 through Comcast working. When I run the Comcast speed test, the ipv6 upload is really slow. The ipv4 is fine.

      This is on a Windows 7 PC.

      http://stage.results.speedtest.comcast.net/result/585946284.png

      Any ideas where to start?

      Thanks for any help you can provide.

      Todd

      Problem Solved

      Turns out it was a setting on my NIC.

      I needed to change "Large Send Offload v2 (IPv6)" to disabled.

      This is found in Device Manager > Network Adapters > <right click="" your="" adapter="">Properties > Advanced

      Hope this helps someone!

        Hi toddhigg

        Do you have traffic shaping enabled for the IPv6 Rules ?

        These problems you describe was also reported in the past in combination with traffic shaping and IPv6.

              This is the only ipv6 rule I have enabled, and it's on the LAN side:

              Proto    Source    Port  Dest  Port  Gateway  Queue  Shed
              IPV6*    LAN net      *      *      *          *        none

              Thanks!
              Todd

                  Have you tried the speed-test with a PC directly connected to your cable modem?

                    Yes, but that one only tests download speed.

                      Plugging my laptop into the cable modem works just fine. I get good upload and download on both ipv4 and ipv6.

                            I have determined that the problem lies somewhere with my PC.

                            I connected my laptop to the same switch as my PC and ran the test. It worked fine on the laptop.

                            This pretty much rules out the router as the problem.

                            Thanks,
                            Todd
