I have had a problem for a long time where my modem locks up or resets frequently due to high signal variations. Multiple truck rolls hasn't resolved. As the problem has dwelled, I have increased my data collection and understanding of broadband signals and I perceive the signal variations are caused by noise upstream of me created by human behavior.

This graph represents similar behavior as I saw over the summer - now in graph form. During lunch, dinner and after 9:00 p.m. I have internet again and the sweetest signal characteristics. This noise creating signal variability and my modem drop/locks can only be caused by human behavior. And upstream of me as the behavior doesn't mirror any activity in this house.
[att=2]
This graph represents a narrow time frame of signal variation (from what I could screen capture), and modem drops/locks, from 11:00 a.m. to 5:00 p.m. on New Year's Day. A friendly walking of the neighborhood, the only activity I could discern was the use of two way radios during a family reunion 20 feet off the next pole upstream. (This neighbor is not on Mediacom network.)
Given the patterns, I perceive I have at least two noise sources upstream. (The neighbor's children aren't on the two way radios all day from 9 to 5.) And planes aren't landing all this time at the small airport nearby. I perceive there is also an ingress noise source, or like.
Also, I know that in this neighborhood not one of the unused ports on taps is terminated with 75 ohm terminators. And the neighbor who I do share the same pole described above does not have his POE block bonded to power box.
Anyone have similar problems? And what is the fix?
Send help, please.
