Non stop packet loss when gaming

I have been experiencing nonstop packet loss while gaming and streaming for weeks now. I have restarted the modem, upgraded to a new modem, updated my drivers, and had a technician come out twice to check the connection. Both times, I was told that everything was good on their end and that they weren’t seeing any packet loss.

However, when I showed the technician the packet loss I was experiencing, I was told there was nothing they could do. I don’t know if this is related to maintenance or updates being done in the area, but the issue has been unbearable and has been going on for weeks. I would really appreciate it if this could be investigated further and resolved.
