Re: Slow WiFi with Android Marshmallow & IPv6?

I think it's important to keep in mind this issue is really minor for most people. For most end users all they care about is that their Spacebook comes up in their browser. Once the system admin is able to implement a hack/workaround, no matter how sick it is, and no matter how unfriendly to the

Re: Slow WiFi with Android Marshmallow & IPv6?

Because Android's IPv6 implementation is straight out of the standards books. There are no hacks in there that mask problems when a network manager makes any mistake with IPv6. Strict standards interpretations always force people to clean up their networks. Now you see how nefarious the IPv6 s

Why Android doesn't support DHCPv6 is detailed here: https://code.google.com/p/android/issues/detail?id=32621#c53 They say to use SLAAC and RFC6106. I happen agree with their reasoning. It is Microsoft who needs to change, not Google. The IPv6 standard does not require DHCPv6 and it's a mod
