I do understand the figures! Fabretti is right about mentioning work from home having no clout; reason for that is nothing about your personal circumstances will carry any clout. You are not breaking any of VM's rules by working from home.

It's always best to post the complete downstream, upstream and event log so that any correlations can be seen. You'll be surprised at what the downstream stats can tell you about why upstream is mis-performing.

In your case, the first thing I notice is QPSK modulation. This means that your upstream circuit (shared with others in your locality) is noisy. Normal modulation is 16QAM (4 bits/symbol) and your QPSK is 2 biuts/symbol. Thus the shared resource is sliced in half.

Is the upstream power more or less stable at 40 dBmv? Or does it jump around in 3 dB increments when you refresh the upstream stats page?
