Dall'inzio del LOGl a connessione era 9999Kbps in Downstream ad ora invece senza mai aver riavviato il router o perso la linea ecc... mi ritrovo con 8386Kbps in Downstream, tutto questo senza perdere la linea! Non capisco come sia possibile, non ci sono filtri e il router è sulla presa principale. Il rumore quando il Downstream era 9999Kbps stava da 8.8 a 9.4 ora con 8386Kbps in Downstream il rumore sta a 12.1
