Windows 7: Ipv6 doesn't work after waking up from sleep mode

Ipv6 doesn't work after waking up from sleep mode

Hi All,

I had a problem about ipv6 on windows 7 for a long time. I have a ipv6 & ipv4 dual stack network.
Every time I wake up my computer, the ipv6 cannot work. The appearance is that I can't ping and access ipv6 website.
But after some research, I realize that only the DNS part is broken.
When I ping the ipv6 site like, it tells me it find no host, but if I use nslookup, I can find the ipv6 address. And the following are my tries:
ping -- not work
ping 2a00:1450:8001::68 -- does work, the ip is the address
ping -6 -- does work like the above

Thanks for your reading, any suggestion will be appreciated.

Amazingly, well over a year later, this is still an issue ... this exact problem happens to me and has since I started using 7 ...

Does anyone know a fix for this yet? Is this a very long standing bug that has not yet been resolved?

Thanks ...

It's not great, but after reading some other things I got v6 working again by disabling it on the interface (via the interface properties in control panel under network) and then re-enabling it after the address had cleared. It's not great, but it's sure better than a reboot.
