I've been experiencing packet loss in the evenings during peak hours (see attached) and the cable company continues to imply that the issue is with my modem or my home network. I have an all-in-one modem/router (hop 1) and hop 2 (10.135.128.1) is not part of my local network per the Local Network Discovery feature of PingPlotter. So my question is, seeing that hop 1 is entirely without interference, is the problem on my end or theirs? I don't want to go down the road with them where they implicate every WIFI device, treadmill, fluorescent lighting, etc. as the cause of my issues.
