Thanks for getting in touch - sorry to hear about your lag issues.
We had a chance to dig into the results you provided (thanks for sending over those .pp2 files!), and from what we can see - you've got some patterns of latency starting at hop #1 that are carrying through your entire route to your final destination. This pretty strongly implies that the culprit in your issue could be somewhere between your machine (the one running PingPlotter), and hop #1 (likely your modem/router).
Your next goal here should be to eliminate any variables (that you have control over) to see if you can isolate what the culprit is. If you're on a wireless connection, moving to a wired connection is a *great* first step. You could also try running PingPlotter on a different network all together (if possible), to see if the issue may be related to your machine (if you see the same results on a different network - this would be a pretty strong indicator). Anytime you're eliminating a variable, make sure to keep PingPlotter running so you can see if you notice any changes in your results (as this can help you identify what may be causing your problem).
We've got a great guide that goes over using PingPlotter to troubleshoot network problems like this one, which may prove helpful to you here:https://www.pingplotter.com/fix-your-network
