Occasional loss of internet services

I apologize everyone, I haven't checked here in a while. I ended up getting a tech to come out and he checked my lines, replaced the ends of my cable connections internally, but didn't touch anything from the box or the line past it. He did multiple tests on his equipment to show I am connected and my signal strength is strong as well as my speeds, which is good, but since I wasn't having an issue right at that moment, I guess he took it as issue resolved. I tried to talk about what I see in the modem and show him the logs when I have my reported outages via my signal monitor, but didn't seem interested. I continue to have issues to this day, (it actually went down again as I was typing this) and they seem to happen mostly during the day, and it is steady and strong after midnight.
