cm1000 power levels
Hello, I've been having issues with my Internet since switching to gigabit with Xfinity in May of 2019. I recently switched from an Arris SB8200 to the CM1000 and saw an almost immediate improvement....
You've got a lot of errors in your line. Something to keep in mind is that the cable connections page is a snap shot at the time you accessed it. The power levels can vary a bit. They should be withing 3.5dbmv of each other. You've got a range from -6.9 to -12. so roughly 5.1dbmv range.
What I'd do? move the modem (temporarily) to right where the coax enters the home. Then run the same test and repost back here. If the levels are good, its something within the home such as wiring/connector/etc. If the levels still aren't decent, then xfinity needs to look at the wiring external to the home.

After moving the modem, the power levels changed as shown ranging from 0.6 to 5.1 bringing it closer to the 3.5 but still not there. Upstream dBmV 46.3, 47.0, 47.3.
- No errors so far. Watch it for a bit and see how the errors do. Power levels much better
No more error messages so far. This seems to have fixed it. I extended the line to get the modem where it needs to be for now until Comcast can get out here to run the new cables. Power from -1.7 to 3.6! Nothing showing in the event log! Thank you so much!
