En determinadas condiciones (dependiendo del AP, del cliente, etc) el
WiFi se des-asocia del AP luego de un período de inactividad.
En uno de mis dos servidorcitos en casa, el que está en un lugar donde
no tengo UTP, tengo un ping al default gateway corriendo siempre.
Horrible, ya se, pero funciona :-D
(Hago mas cosas horribles, como remachar un prefijo IPv6 estático en el
rc.local, pero prefiero dejarla por ahí :-) )
