Tengo un problema bastante molesto ya que cae la conexion PPP sin motivo aparente. La solucion que tengo es rearrancar el router.
Normalmente despues de haber sincronizado este (ambos leds siempre en verde) no hay manera de hacer ni un ping ni nada.
1) El router me da el siguiente log:
------------------------------------------------------------------------------------------------------------------------------------------------------------

2) Os copio y pego tambien los parametros que tengo cuando me funciona bien la conexion. Notar que aparecen errores de Bad VPI/VCI.
