Salve a tutti,finalmente ho trovato un forum preparato che potrebbe risolvere il mio problema!
Premetto che prima di postare mi sono letto altri thread relativi al mio problema..
Allora..ho win xp,alice 640 e modem michelangelo usb digicom..
Circa un anno fa se non sbaglio,quando c'è stato l'upgrade da 640 a 1 mega ho aggiunto una presa rj dietro al pc,da qual momento (non so se è colpa mia o di modifiche telecom) ho spesso delle disconnessioni,soprattutto appena accendo il pc,poi possono succedere ogni ora con ogni 10 ore..
Per risolvere il problema (è da un anno che tento),dalla prima presa ho tirato una coppia che mi fa solo il pc e un'altro cavo che mi deriva in parallelo 4 prese telefoniche..
Nel modem ho trovato casualmente un'utility che mi fa questo log:

Ne posto solo una parte,perchè poi è sempre uguale..
Ho visto che rifacendo le giunte il valore di downstream è salito sui 28,per poi ritornare a 27..
Questi valori valgono più o meno per tutte le prese tranne che per una (che ovviamente fa parte della linea telefoni) che ha dei valori di downstream inferiori ai 20..
Dove sta il problema,se non sbaglio la centrale è a 200 metri da casa..
Ho pensato che fosse anche problema di modem ma non ho mai provato a cambiarlo..

Rispondi quotando
Anchio ho un Modem della Digicom il Michelangelo usb cx dove si trova questa Utility Ciao e Grazie
