Ho un problema con la mia connessione: è lentissima, non supera mai i 900KB/s in download da qualsiasi server, il ping è alto, però aggancio la portante piena, ho 2,3 di attenuazione down e 1,5 in up e 30 snr in entrambe le direzioni, sono collegato al modem con cavo ethernet.
A cosa può essere dovuto? Al modem?
