Dear Richard,

    RM> Sorry ... no clue.   
    RM> For my it always shows proper dualstack.   
      
   After a software update on the phone, a miracle happened:

   The only thing I don't understand is why the test says "SLAAC=no" while in   
   fact it *is* SLAAC (I don't have any DHCPv6 server on this network, just a   
   rtadvd).   
      
   OTOH, "after" does not always mean "in consequence of."
