I'm using NetworkManager with its internal DHCP client. I have working IPv6 autoconfiguration support in my home network with 7 devices with different operating systems. When I plug a USB network card into the laptop IPv6 is configured sucessfully. But with the wireless card IPv6 autoconfiguration doesn't work. When I manually add an IPv6 with "sudo ip -6 addr add

/64 dev wlp1s0" I can ping IPv6 targets. So there seems to be an bug either in the driver or maybe in NetworkManager which prevents autoconfiguration from working, can sombody look into this? I'm glad to help and provide further informations or test things out.
