Titolo: 827 PPPoE passaggio da 4 a 8 mb

Ieri Infostrada mi ha fatto l'upgrade della linea da 4 a 8mb con il 
risultato che non arrivo a 8192 di velocita', nel download
si e no arrivo a 500kb/s,....... c'e' qualcosa nella configurazione che ho 
sbagliato??

 sbagliato??
Potrebbe essere una cosa di "profile" e non di configurazione.
L'ultima volta che la mia linea telefonica e' stata aggiustata mi sono
connesso sempre a 8192 ma
per due giorni non otttenevo piu' di 2mbit di roba. Aspetti un paio di
giorni?

A mio avviso la modulazione DSL � errata (T413???? ) dovrebbe essere G-DMT
inoltre ha un valore di portante bassissimo
 


il fatto che ti dia 7680 come velocità in download, forse dipende
dalla qualità del sengnale per cui non riesce a negoziare gli 8mbit
per il resto sembra configurato giusto prova solo a inserire questi
due comandi sotto l'interfaccia ATM0:
bandwidth 8192
max-reserved-bandwidth 100
il comando bandwidth è sempre consigliato sulle interfacce wan, oltre
ad avere un valore descrittivo utilizzato soprattuto dai protocolli di
routing ha un significato "nascosto" nella definizione dei buffer di
memoria interni del router/ios (almeno questo è quello che mi disse
tempo fa un omino Cisco)
Il secondo ho imparato a mie spese che va sempre inserito sulle
connessioni ATM soprattutto quando entrano in gioco i pcv con valori
definiti di pcr/mcr.
