Re: 50mb Broadband Upstream gone down

Not many people would worry about 1.75 moving down to 1.65! But I do see anomalies in your stats.

1/The modem reports a maximum upstream rate of 1.072 meg. So that can't be right, particularly as your upstream is modulating at the full 16QAM.

2/
At 58.21 dBmv your upstream power is maxing out. Can we see the event log please? This might throw light on what's going o. What other bad experiences occur?
