xfininty internet connection - f intermittent slowness and disconnects
We have "up to 1300 Mbps down/up to 35 Mbls up" service tier and are using an MB8611 modem.
Things look okay on diagnostics with the exception of a very high number of uncorrected vs corrected errors (roughly a 2.5:1 ratio) on the downstream channels:

We have no in-house splitter; there is a single continuous coax cable connecting our modem to the service box outside. The cable is RG6/U quad-shield cable that was installed before we moved in -- it used to go to a splitter but since we have not had cable TV service in so long, I connected it directly to our cable modem when we recently switched to xfinity internet.
