Intermittent Packet Loss and Speed Reductions for 5 Straight Months

I have been currently experiencing intermittent packet loss and speed reductions since moving into a new apartment across town. To recap I have had 3 techs come out so far and they performed some of the following:

  • Tightening cables
  • Removing splitters and adding new ones
  • Undoing the last tech visits work
  • Opening my coax port and looking at it
  • Replacing modem

Of which none of these have fixed the issue at hand. Since the problem is so sporadic but daily, I assume it's hard for them to gain any information when doing signal tests. When doing packet loss tests myself by keeping different logs going it can happen anytime of the day but less in the middle of the night 12am-4am. However, during the day 10am-11pm it happens more often. Here are some sample images of the packet loss happening that I've managed to capture

And what it basically looks like when doing a ping -t 8.8.8.8 in the terminal when it happens

The above is when I tried to get the downstream signal strength when the problem was happening. During that time the upstream signal strength did not load. I will keep trying to grab them as they are happening and post updates. 

Edit to include upstream signals when problem is happening:

One thing to note as well, when this problem is occurring it happens on every device, wired or not. Another key note is that the public provided Wi-Fi by Xfinity (Xfinity Mobile) does not have this issue happen to as ive tested both at the same time. Only my personal connection has this issue.

So far, after three tech visits, the conclusion was that it was nothing to do with inside my apartment complex as everything looks fine. I've tested multiple coax cable connections, and both have the same issue. I have even tested plugging the modem straight into the feed that comes straight into my apartment before the 2-way splitter. I believe I have eliminated every potential problem on my end within my own unit. I am kindly requesting a line tech to check my lines for any damage or whatnot that can be the cause of this issue. I do not need another person to come and test my modem strength inside again and tighten some wires. Thank you for reading and your time.
