My xfinity internet service has been steadily worse over time. Early last year, I bought a Docsis 3.1 Modem and received speed bumps to the current speed of 900mbps. Initially, the speedtests were blazingly quick and easily exceeded the target. fantastic. However, approximately a month ago, I began to notice disconnects and reduced internet speeds; a few weeks ago, it was around 400-500mbps, and in recent days, it has been around 100mbps+/-50mbps.
I began troubleshooting and discovered that the modem has low SNR values on various channels, as well as “uncorrectable codewords” that appear to be very high, indicating that there are numerous problems. Rebooting the modem appears to help for a short period, however this may depend on the time of day. I’m not sure about that. The appropriate modem tables are listed below.
I tried an older docsis 3.0 modem and observed that the SNR and errors were still out of spec, but comcast was taking too long to deploy the new modem, so I switched back. Everything is connected to an amplified splitter that has been in the house since we moved in, however connecting the modem and coax into a conventional splitter results in the same SNR/error/speed difficulties.
