Slow upload speed test through ipv6 ***SOLVED***

toddhigg

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.

Any ideas where to start?

Thanks for any help you can provide.

Problem Solved

Turns out it was a setting on my NIC.

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

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.

Nope. No traffic shaping enabled.

Mhh how many IPv6 rules are enabled at the moment ?

toddhigg

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!

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,
