Eu finalmente encontrei a solução. Pode demorar alguns loops para se conectar, mas no final end autentica. Ele funciona no OS X El Capitan 10.11.4, qualquer ajuste para versões anteriores do OS X (se necessário) ou Linux deve ser fácil.
Cuidado com o que precisa ter o "wget" instalado e no $ PATH.
Para iniciar o script como um agente do usuário do OS X no login verifique isso . Aqui está o script:

#
# OS X Script to automatically reconnect to a Vodafone Community AP
# when the connection drops.
#
# It's designed to support to be launched as an OS X login agent
# logging to the console.
#
# Tested only on OS X EL Capitan. It should also run on Linux without
# many modifications
#
# Version 3.0
# Author: Michele Dall'Agata
#
# CHANGELOG:
#
# v3.0: All connection parameters are automatically retrieved from the
# Vodafone Station.
# Force the use of Vodafone-WiFi APs.
# Cleaner log.
# v2.2: Check after restarting the WiFi if the connection is up and continue
# in case. It happens quite often.
# v2.1: All references to the WiFi interface now correctly use $WIFI_IF.
# v2.0: Reorganized the logic.
# Added section OS X specific.
# Loop waiting for WiFi connecting after restarting.
# Added $WIFI_IF variable for WiFi interface.
# Check if it is a Vodafone Community AP.
# Fixed all wget commands.
# Complete although stripped logging. Now it's clearer which step
# is executed.
# v1.1: Restarts the WiFi interface.
# v1.0: first working skeleton. Hey, it did the job! :)
