Line issues can be challenging. Even the connections page doesn't always help that much as it takes a brief snip when the page is opened. the logs help because they show longer term (which indicate line issues by the t3 errors). but if there's something obvious on there it helps.
If the isp's checked the line, try moving the modem to right where the coax enters the home. they rarely look at anything in the home and just ensure the signal is good up to where it goes into the home. After that its on the home owner to ensure the cables/splitters/etc are all in good condition.
The tech checked the lines from the box outside, junction box attached to house, my tele box in garage, and then the line all the way through the house to the modem. He stated, which in previous experience could have been just to get done, that the lines were clean. He even said that testing past the modem was clean, however, same story same dance scenario.

Here is the current event log that corresponds with the cable connection page.
Also apparently my post from yesterday did come up and I can see it now in the thread showing yesterday.
Thank you again.

Your powerlevels look pretty spot on.
But your event logs are showing issues connecting back to the cmts.
You're caught in a problem.
The power levels do look good. but the logs dont. And the ISP has checked the line.
so is it still the line or is it the modem?
Unless you have a backup modem, its tough to prove either way.
I've actually rented a modem from an ISP for the $10 a month (only rented for a month) to check which is was.
right now I've got enough backup modems that I don't have to do that anymore.
Lol, this is where I figured that I am. I do have the spectrum provided modem, picked up a few days ago. I have been too prideful to accept that my modem could be the problem and wanted to check on here first before fully accepting defeat. I do plan to commission the spectrum modem to see if things become more stable which in turn will tell me I just need to get another modem.
Last question, would factory reseting the modem do anything? Or is this more hardware malfunction kind of thing and its a lost cause? Of course this is assuming the modem is the actual culprit and nothing upstream.
At this rate, I am just trying to find some piece of mind.
Thank you again
