I just complained again and they said they would check again, i watched over the modem and noticed they changed the modulation to QPSK and cycled through various power levels just to end up locking back to 16QAM at 61dBmV?! Is this normal and is QAM or QPSK better i was under the impression that QPSK was the better of the two but i dont know much

Thanks again
Adam
