BUON NATALE a tutto il Popolo dei 6db!!!! :)
buon Natale e felice anno nuovo a tutti voi ;)

Ciao a tutti,
stavo cercando di capire se effettivamente un passagio ai 6db potesse aumentare la mia banda in downstream.
Ecco i valori della mia DSL:

se abbassi l'SNR Margin, guadagni un botto, saresti mooooolto vicino ai 20Mb/s
una volta che entri in modalità telnet sul modem
ricordati di usare il comando adslctl configure --snr 65450
tenendo presente la tabella di conversione in base al SNR che aggancia il modem
