zephyr83 ma è assurdo che non si riesca a trovare una soluzione
Io dal mio punto di vista vi riporto la mia soluzione passare ad Openwrt (se si è disposti a rinunciare alla possibilità di utilizzare telefono/rj11),
le disconnessioni continuano a capitare ma almeno nel giro di 1 minuto
viene ripresa la connettività (questo è un limite di crontab il minimo ed eseguire un script ogni minuto).
uptime 19 days (ovviamente riavviato in seguito a mia volontà di per se il router resta sempre acceso salvo perdite di energia elettrica che potrebbero comunque capitare)
logread (circa ogni 12 ore e sono su Iliad)
