Allora, parliamo di valori con linea telefonica NON attiva e parliamo di valori in "downstream"<br>Attenuazione: 12db<br>Rumore: 30/32 db<br>questi sarebbero i parametri ottimali.<br>Ora, disconnessioni, purtroppo ci sono passato anch'io quindi ti posso dire come avevo risolto temporaneamente.<br>Se navighi tra i menù del tuo Netgear, troverai alla voce (se non ricordo male) "ADSL Setup" il form "MTU" che di default è impostato a 1.500 (MTU indica le dimensioni dei pacchetti che vengono inviati), diminuendo un po questo valore (come già detto in precedenza) e impostandolo su 1.492 o 1.490 la connessione è risultata più stabile e anche la navigazione più veloce.<br><br><hr id="stopSpelling">Date: Sat, 17 Apr 2010 15:39:42 +0200<br>From: lorissuper@gmail.com<br>To: gl-como@lists.linux.it<br>Subject: Re: [gl-como] [semi-ot] Problemi di..linea<br><br>

aggiornamento: niente fruscio sulla linea, ma il router si è
disconnesso e riconnesso da solo(cosa che ha fatto spesso negli ultimi
giorni con la comparsa di sto problema), vi posto i valori con linea
telefonica aperta e chiusa, quali dovrebbero essere dei buoni valori di
"rumore"?<br>
