eccomi qua...ho usato tutto il giorno il router Cisco per provarlo e per documentarti quello che intendevo....
la mia premessa è che abito in una zona dove quando arriva la notte (leggi umidità) sulla mia linea telefonica si presentano dei "rumori" del segnale...ho contattato più volte la Telecom al riguardo ma niente....mi sono abituato a ciò e per cui ci convivo....
il problema è che ogni tanto perdo il segnale della linea ADSL, succede sia con il router Cisco che con quello Netgear, ma il router Netgear dopo 30sec-1min ritrova la linea...si riconnette e riparte il servizio internet...il router Cisco, perde la linea--->ritrova la linea---->non riparte il servizio internet
ti posto i messaggi del router Cisco in fase di avvio router e connessione ADSL

ammetto di essere completamente a digiuno di queste tipologie di configurazioni Cisco ma ho notato che la connessione ADSL parte solo e solamente dopo la comparsa di questo messaggio

per questo chiedevo se era possibile far ripartire la connessione ADSL come se il router fosse stato accesso per la prima volta
