Te pasaría el backup completo pero tendria que cambiar claves ya que las cifra y si las cambio a mano no te van a servir... espero que puedas sacar la info que necesitas para resetear el router y configurar la conexion de iplan.

donde figura la ip 123.123.123.123 es donde tenes que poner tu ip y despues cambiar tambien el gateway.

Espero te sirva, saludos!

Astor

tambien puede ser el pass iplan2948

saludos!
