Thanks @ComcastMichael for your help with troubleshooting arranging a tech visit. It turned out to be a signal problem with the Xfinity line before the main line coming to our house. SNR levels are now in the low 40's db (from the low 30's) and the speed is back where it should be. Thanks!

Hi, I've been having very slow internet speeds and frequent droppin/outages since April 2019 and wondered if someone on this forum might be able to assist. If I power cycle the modem and router, sometimes the download speed increases dramitically, but then degrades over a short time (a few mintues or hours). I've connected the modem directly to multiple computers (bypassing the router) and tested the speed and no improvement. I have internet service download speed up to 60 Mbps and am lucky to get over 2 Mbps on a consistent basis.
I had a Xfinity tech come over a few months ago and reset the modem and the speed temporarily improved and claimed it all looked good from their end. I contacted the modem Cust. Service (Arris) and they reviewd the power levels and said I have a signal problem from Xfinity. The signal levels and error log screenshots are below.
Xfinity Performance Plus Service: 60/5 Mbps
Modem: Arris SB6183
Router: ASUS AC1900
The status is from 07/04/2019 and the corrected/uncorrectables are from about 12 hours since last power cycle.
