network Packet loss issues? Help please.

[PdaddySmalls]

So for the past month I have had constant packet loss going from 3-10% during the morning and afternoon. Then around 3-5pm everyday it jumps up to 10-40% constantly where it sometimes hard to even watch youtube and gaming is not even possible with that much packet loss. I've had my isp come over twice they switch the router/modem mix and tested it twice but it was in the morning.. and saw less than 1% packet loss. Then they said they would come by sometime to replace all the coax cables (sorry if im wrong) throughout the house but never gave a date but they said its most likely not the issue and I somewhat doubt it too since most people I know have had packet loss issues had there modem or router replace then it was gone.. But not me. Im not too sure if it is me or my isp I have 3 xbox consoles in my house and two computers and they all receive packet loss on games and live streaming. so I'm not too sure it is me since they all have the same problem but then my isp says they see "no packet loss".. So ive kind of been trying to see if I could find out if the issue really is me or not running tracerts and ping tests (hopefully im doing them right) and something i've notice it always and I mean ALWAYS says "request timed out" on the 7th hop idk if that could point out where the problem is or what lol. Ive posted about this like five times im just really tired of lagging everywhere when gaming and makes it very frustrating if anyone had advice on what to do I will DEEPLY appreciate it and love you forever. 

Heres a screenshot of one of the tracerts:
