¿Han quitado los límites al fastpath? Es que activo el perfil fastpath y me sigue sincronizando al máximo que da la línea.

Me parece que el Fastpath no lo tienes activado ya que donde dice Traffic Type dice ATM cuando debería decir FAST o FASTPATH.

Sí que tengo el fastpath activado:

Otra cosa es que hayan modificado el funcionamiento del perfil y ya no activen el fastpath sino que dejan el interleaving con la menor profundidad posible, que sería lo mismo que hace Vodafone.

Me autocontesto. Efectivamente es lo que hacen. Mirando en las estadísticas del router:

pero eso solo ocurrre con el fasphat activado, o no hace falta activarlo?
