The VM bod should have noticed that your downstream SNR is reporting 33/34 dB which is below spec. That said, the Hub is reporting no post-R/S errors (uncorrectable data).
Well if the 'VM bod' as you call them, were in any way 'technical' and actually had any real understanding of how the technology works, then yes, I would have expected them to notice it, but as they aren't then we really can't expect anything too far beyond 'have you turned in off and on again'!
Incidentally, are you as intrigued as I am by the fact that the Hub 4 appears to be able to measure the D/S MER values to six places of decimal? Furthermore, many of the values are identical to the same six places of decimal - which does seem to be stretching credulity somewhat, no?
Bottom line, and I have said this many times before, based on what we are seeing the values as displayed by the Hub 4 absolutely cannot be regarded as accurate - maybe it's just some oddball reporting issue and a bug in the firmware - but on that basis, can we be sure of anything else that the hub is claiming?
