En el mismo día que se realizaba el UWC en Buenos Aires, la gente de Ubiquiti publicó una actualización de Firmware para el AirOS en su versión v5.5.2.

Los cambios y arreglos son varios tanto a nivel de funcionamiento como de la interfaz web de configuración. Se ve que Ubiquiti le esta dando mucha importancia al tema de la seguridad en sus dispositivos y es por eso que ha agregado certificados SSL en todas las interfaces web, encriptando toda la información que se trafica entre el dispositivo y el navegador. Ahora viene activo por defecto el acceso por HTTPS y se ha removido la funcionalidad admin.cgi (ésta era explotada por la vulnerabilidad de acceso).

Algo que encontré gracias a esta actualización es que Ubiquiti dispone de unos equipos especiales NanoStation M6 los cuales pueden trabajar en las frecuencias de 5.9 Ghz a 6.4Ghz, rango que tienen permitido utilizar los operadores de telecomunicaciones en Rusia (es por ello que ésta versión solo está disponible en ese país).

El listado de cambio completo es:
