No te puedo ayudar, pero si puedo aportar mas preguntas al post. Tampoco puedo navegar ni descargarme nada durante unos segundos, luego parece que la conexion resucita. En el system log me sale esto:

Nose si el amigo tanker nos podrá ayudar, o alguien que le pase lo mismo y le hayan dado una solucion.
Ya no se si es culpa del router, de jazztel, o de la linia.... Mi router es DLink G604. Mi central granollers. Y la atenuacion de la linia la tengo fatal a 63 US y DS.
El test de adsl4ever me da 420Kbps / 512. Lo que esta bastante bien.
Ayuda porfavooooooooooor!!!!!
