Tengo un AP 1260 que actualicé esta mañana. Antes de la actualización, el sistema permitía ssh y respondería a pings en la red, sin embargo, ahora no responde.
Conecté un cable serial y navegué por la configuración. Parece que no puedo encontrar nada malo, y activar la depuración ssh no produce ninguna salida.
Intenté regenerar la clave RSA en la posibilidad de que ssh no se conectara, sin embargo, no ha afectado la incapacidad de contactar a la unidad a través de la red.
También intenté activar "enrutamiento ip" e "ip cef" pensando que podrían ser el problema, pero sin efecto. También agregué una ruta estática predeterminada a nuestra puerta de enlace de administración con la esperanza de que tal vez fuera un problema de ruta predeterminada, pero tampoco ayudó.
Aquí está la versión actual de IOS en la unidad:

Cualquier sugerencia sería apreciada, estoy bastante perplejo de por qué esto de repente saldría mal.
