Intermittent network disconnection for CM1000
Hello all,
I've been having issues with my network which started 3.5 weeks ago. I'm experiencing network dropouts within a specific timeframe. I've already had my ISP tech stop by and they've explained that it's the splitter/POE filter that's causing it and went ahead and replaced them as well as provided me with their own coax cables, they've tested it and said it's good. This was a 2-hour job and multiple tests were done at the same timeframe my internet usually dc's. This was Thursday (2/4) and fast forward to the weekend and the issue still persists. I have gigabit internet, I've read through multiple forums and majority are asking about the logs so I've attached a file, unfortunately I don't know how to read these and cannot determine if my connection is good or not. My modem configuration is on default since whenever the issue happens I go aheand and factory reset it. Any assistance is greatly appreciated!
Modem: CM1000
Firmware Version: V6.01.07

Your power is going in and out of spec from the logs.
Do you also have your cable connections page info? (shows the signal strengths)

Hello Plemans,
The system keeps removing my response. Not sure why that's happening, I do not see any errors/warnings. I post it and I see it for a couple of minutes then it disappears.

this website is broken. I cannot upload my downstream table. for some reason it disappers a few minutes after I upload it with no notification or errors. I've tried uploading it as a photo, screenshot, attached table in this response. Nothing seems to work.
