I had my IPv4 preferred over IPv6, via the Microsoft supported reg entry (http://support.microsoft.com/kb/929852). Win7 x64.
After upgrading the wifi driver for my Intel 6200 card to the latest (5.1.1, coming from 14.3.1),the preference is completely ignored it seems. No variation of the reg value seems to function.
It's as if IPv6 is permanently prioritized above IPv4.
I had IPv6 setup via a 6in4 tunnel, and config was operating acceptably until this driver change. Nothing else changed.
How can I get Intel support to answer to this?
