I've got an issue with this firmware reporting my cable connection as "Poor" even though I'm getting full upstream bandwidth (41+ Mbps of a theoretical 40 Mbps max).

nsne have you started your own thread?
Make sure to include a screen snip of the cable connections page and event logs.

Hey, plemans. No, I haven't started my own thread (yet). FURRYe38 signed off saying, "Let us know how it works for you..." so I was obliging that request.
I'm attaching a screenshot of the text output from the Cable Diagnostics. I didn't include the event logs, as they seem to have some MAC info in there that I'd rather not post publicly.

Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to power OFF the modem for 1 minute then back ON.

I have the same issue. This is recent and I do have a splitter which was installed by the cable guy (Comcast). I recall him actually swapping out the previous splitter because he told me that the old one was causing signal issues, so I am very confident that this issue is the cable modem itself (perhaps due to a recent FW update). The splitter was replaced in early 2021, so it also isn't that old.

What issue are you seeing?
Can you remove the splitter and run the modem with out it temporarily and see if the problem continues?
Please post a copy and paste of the modems connection status page.
