Packet loss starting at hop 2 through end destination.

I have been experiencing a lot of packet loss starting from hop 2 through the end being google dns 8.8.8.8 or a comcast server that's a few hops further in the chain verifying its something on there network side / local node. 

Using ping plotter to verify, and CMD prompt pings to verify packet losses. Used multiple devices, had modem swapped 3 times. 

Multiple techs have come out and 4 of the 5 found nothing. One found packet loss on his device but nothing further was done. 

Any help or support would be greatly appreciated this happened 7 years ago when we got the place than was fixed, now its returning.
