IPv6 and WiFi routers

Hello,

I have been trying to deploy IPv6 for a few months now, to all our direct clients. The first problem I have faced is that 99.999999% of them use WiFi routers that don't have IPv6 support. Those that do support IPv6 are disabled and clients would much rather be on a private IP (that is masqueraded) than have a public IP.

Is it the case everywhere? Meaning do WiFi routers in Europe, Australia, united states have that function by default or no?

I have been trying to get a few vendors to talk to their supplier in China to enable v6 on the cheaper routers (all they need to do is upgrade the firmware) but China doesn't care much for V6.

I know that most places will have minimum requirements for equipment to be imported and IPv6 is one of them.

IPv6 has certain security function over ipv4, would that be a reason why Chinese companies won't include it? Allegedly blocks their access?

Those who connect directly to PC are fine though but that number is really small.

I'm doing it through pppoe though by assigning a /64 per access router; clients are meant to get a private IPv4 and IPv6. How are the rest of you doing it? Why is dhcp better? Or is it?
