DSL-2640R problema connesione

[antonio32]

Ciao a tutti come da titoli ho un problema con modem router dsl-2640R . Il problema si è presentato una settimana o due fa quando ho notato che la connessione in download era molto lenta facendo il test su internet mi è risultato che in download avevo solo 2Mb mentre da contratto (con Infostrada ) ne ho 8Mb , ho provato a cambiare le impostazioni a resettarlo ma niente allora ho provato un vecchio modem e con quello funziona bene allora ho chiamato Infostrada e mi hanno consigliato di aggiornare il modem-router ma questo non mi ha dato nessun risultato . Ho provato a richiamare l'assistenza ma non mi rispondono. Il router funziona perfettamente provato su Linea Telecom e va al massimo. Queste sono le statistiche attuali del modem router .

Ho notato che se metto G.DMT la connessione migliora è facendo lo speedtest ottengo quasi 6MB. però in questo modo non sfrutto gli 8 mega non capisco quale il problema con l'ADSL2+.

Statistiche con Adsl2+ e speedtest (test fatti senza nessun altro apparecchio collegato alla linea telefonica)

Dalle statistiche ho notato che RS Correctable Errors ,RS Uncorrectable Error con Adsl2+ sono molto elevati mentre con G.DMT sono a 0(alcune parti del primo sono in ITA per colpa di google traduttore)

Re: DSL-2640R problema connessione

Ciao,
leggendo le statistiche che hai fornito noto che il valore in download di SNR margin risulta molto basso addirittura sotto i 10dB. Il segnale in queste condizioni risulta essere molto disturbato e di pessima qualità. E' per questo che nei test l'adsl risulta molto lenta in download mentre invece sembra andare molto meglio in upload (il margine di SNR in questo caso è di 22.8dB che è un buon valore)
Il valore di attenuazione della linea in download è un tantino alto (30dB) è buono quello in upload (20dB)

A mio avviso devi controllare la causa del disturbo presente sulla linea, magari verificando la presa dove collegato il router adsl ed eventualmente isolando la presa da altro circuito in serie collegato eventualmente alla spina.


Cordialmente
Marcello

Imposta la linea in G.DMT che la linea e ottima.
Con la distanza che hai non puoi prendere 8mb peni
