ADSL che funziona con tutti i router tranne Cisco 877

[mmarangon61]

Ciao a tutti. Ho provato la mia adsl con netger 834 e zyxel 660h-d1 e funziona. Con un Cisco 877 va giù il link di centrale in modo casuale. Ho una 20 Mega con Tiscali ma con profilo a 16 Mega. Noise margin circa 6.0db. Ho l'ultima versione IOS la *15T6 ed ho provato sia i firmware 3.xx che il 4.0.3 ma il problema persiste. Avete qualche idea? Qualcuno mi vende con ricarica PostePay i firmware versione 4.xx da provare? Oppure c'è una riga da CLI per dire al cisco "se rilevi errori non buttare giù il link"?

Da quello che ho capito si "disallinea la portante ADSL" (il Led CD lampeggia). A occhio la conf dell'interfaccia ATM sembra ok.
Puoi provare questo comando:

sh dsl int atm0 (posta il risultato, per vedere i parametri di allineamento)

Puoi anche provare sotto l' int atm0 a forzare la modulazione ADSL (che adesso é in automatico:

ROUTER#conf t
ROUTER(config)#int atm0
ROUTER(config-if)#dsl operating-mode adsl2 oppure adsl2+, ansi-dmt, itu-dmt

P.S.: cambia la password della tua registrazione tiscali e la prossima volta non postare i parametri del ppp perché il password-encryption di cisco é facilmente decriptabile

Ciao
Ho letto in giro che il 4.0.3 (che poi mi risulta l'ultimo per alcatel 20190) è molto più sensibile a disturbi di linea rispetto a quelli precedenti quindi se ancora non lo hai fatto prova a fare delle prove ad andare indietro nelle precedenti versioni sempre se improvvisamente il led del segnale adsl comincia a lampeggiare..

se però ti si disconnette per timeout fai questa prova:

vai in conf t sulla dialer0 e inserisci

Codice: Seleziona tutto

dialer idle timeaut 3600 either

significa che per 3600 secondi deve tenere la connessione attiva (either= dati in entrata e uscita)

naturalmente al posto di 3600 e cioè 1 ora puoi mettere il valore che desideri


P.S. - Ti ho mandato un messaggio privato

ho anche io un 877 con lo stesso problema...
ho provato sulla linea un DLink, lo fa anche ma MOLTO più di rado, mentre uno Zyxel rimane allineato sempre.
ho una ADSL alice 7 mega, i parametri di allineamento sono buoni, ho provato a ataccare TUTTO dall'impianto interno (prese supplementari e telefoni) ma senza soluzione...

stavo cercando di aggiornare il FW del modem ADSL del 877... mi sapete dare qualche dritta su come fare?
grazie!
