High Ping. Traceroute high ms at 7th/8th hop.

I am trying to trace the source of my high ping issues. With a single device hardwired to my router, and with wifi turned off, I am getting a ping between 75-100ms to www.google.com.

My ISP came to diagnose the issue today, and said they had a ping of 35ms to www.google.com so the issue is on my end.

Here is my data from a traceroute, and I'm not sure how to interpret a high latency jump on the 8th hop (since I believe that is too far down the line for it to be my hardware). I did this test with my router broadcasting WiFi and with other devices connected, as I would normally have my network set up.

Any thoughts on what my issue might be?

Thank you in advance,
