The uncorrected errors are indeed a matter for concern (a good number of post-RS errors is zero, and an acceptable number is the odd one or two per day), but the previously posted network log is an absolute stinker, and shows that the hub is repeatedly losing channels or the entire connection. Hopefully when that disgraceful mess of a cabinet is repaired things will improve, if not then there's an underlying noise issue that VM still need to fix.
Very, very infrequently, customers have problems that despite the evidence of network logs and BQM traces, VM claim they can't detect and that "all looks good from out side". In those cases, you need to have the patience and determination of a saint to force the company to resolve this, or may need to consider getting a new ISP. Hopefully it won't come to that.
